Sweet! Those guys rock, we had such good fun with them.. can’t wait for our next get together! Thanks so much for the compliments, it’s so nice of you to get in touch 👍👌
Duca and Roberta sent me! I look forward to following your channel. The sprayed cork seems like a great idea, for condensation especially. An acrylic binder is much better than 100% expanded plastic, whatever the resin.
A Previous Owner, (PO), patiently fitted cork panels of various thickness, in my Presto 36, in order to conform to the compound curves of the inside of the hull, both ceiling and overhead. Incidentally, He (they) did an excellent job, an act of love, for sure.
Hey Paul, cheers for that. Regarding the cork, for sure, just give me a shout and I can help you out with what to buy and where, just get my number off Steve👍
After tearing out loads of closed cell spray foam in the steel boat, as well as some open cell that was added later, we can confirm with full confidence that closed cell keeps the moisture out much much better and is def worth it on a steel hull. That cork product seems super cool too though! My only worry on a boat would be that cork is known for holding in moisture. Is the spray stuff better that way?
Hey! Good to hear from ya! Thanks for the info on foam! I’m pretty sure cork very little moisture, although it can of course hold some, however when surrounded by acrylic resin it is completely waterproof and acts as an unreal insulator. We will put an episode out in the summer about the testing we are doing before we choose the insulation for our boat, so far it’s been really really good.
Just FYI, both sides of the test sample you were touching in the show are at room temperature. The reason the metal feels colder is because it is a good conductor, where at the cork is not. Same as walking barefoot on a carpet and then onto tile, the tile feels colder even though both surfaces are the same temp.
P.s Jenni here. The sheep wool was so nice to work with and has so many benefits and just feels nice to have natural materials surrounding us I guess 👍🏼 🍃
Thanks, let’s see how it goes! We have some interesting testing coming up too. We wanted to try before we put it on a boat, there some other options we are looking into as well although I’m not sure they are available as a product yeti.
@lewisoverdorp8405 termites, yeah I can imagine they could be a problem. I would love to know more about spray cork and termites, we’re looking at spraying our new hull but you’ve got us thinking now!
@@kenf1445 I'm trying to load some pictures, can't figure it out. I'm Portuguese and my grandma had a cork farm. We brought boxes of tiles back to Florida in our suitcases and thought that would do the trick. Then I was absent for a few years and got termite infested. 50' Prout , solid fiberglass. She had partially sunk from a previous storm so I had to rip out the original vinyl backed foam. Glued the cork directly on the glass and wood walls. Worked great for the sweating but the termites devoured the cork. I never thought they'd eat the glued cork tiles. Perhaps when you spray, you can add diatomaceous earth to the mix. Id try it out on a piece of wood and throw it on some termite hill for an experiment first.
@lewisoverdorp8405 hey Lewis, thanks fella! That’s superb advice! We’re thinking about insulating the boat and termites have quickly become a concern! Diatomaceous you say 👍👌
Darn it! UA-cam recommended this video from 9 months ago and it's full of great info, well presented and interesting. Looks like I'll have to watch your whole back catalogue to make sure I haven't missed anything. I'll be back in 90 days or so when I'm done 😇😂
Love your work - we sailed the Indian Ocean in a steel boat - it had 3 inches of fire retardant polystyrene insulation in deck to water line - cool as a cucumber.. upgraded to an HR - closed cell foam core - but with a teak deck in Greece in summer - it was as hot as hell - do not know how it will go in Scotland in winter with condensation...
Ooooh, that’s sounds fun! So which HR have you got? The first cored ones. We’re the 382 and the 352, they were pretty good, when they changed to davinicell foam things got better - I can confirm a Najad from 2000 is fantastic in a Scottish winter! (They use the same techniques as HR) Cheers for the compliment too!! 👍🤟
I have been wondering about spraying cork in my camper for years, but the only one I could find was 'corksol' and you have to do their course so you can buy the stuff! Thanks for this, I will now have a look at 'sea cork' Will deffo check some of your other vids 😊
Chris - this is really cool - sailed the Indian Ocean in a steel boat with 25mm polystyrene insulation -it was cool as a cucumber - now have an HR with closed cell - sailing in the Med - and it is as hot as hell - an oven in here. So cork sounds good to me. great stuff.
Hey Dirk, the Med is HOT! yeah, the cork is looking like our choice for the boat build however there is another option we’re looking into which I think is better again… just the cost to figure out though. Aerogel…. Seems to good to be true! Btw, sounds like you’ve done some amazing sailing fella!!
On the subject of that flax fibre boat you were stood next to at the trade show. I absolutely adore that look and have been wanting to try and bring that into my interior van furniture design ever since I saw the easy composites channel make that canoe with it.... Do you have any thoughts as to how in the hell I make composite cupboards work in my van build as I'm struggling to think of how to implement it
Sure man, there’s a ton of ways. We will be doing some of that in the boat. Question is, do you want to mould them, buy sheet material or make your own sheets? SaMe for corner mouldings? Mould your own or buy them? What’s your thoughts?
@@SailHub After trying to figure out how to to mould the cupboard, curved corners and everything, I couldn't really get my head round how to make them that way so that they had enough ribs and general structure to hang the doors and runners off of, so my brain sort of copped out and said perhaps it would be easier just to capture flat panels of the stuff in a normal wood frame... Undecided really but would love to figure out how to make the entire curved cupboard in one seamless structure, much like the wood veneer in your current van build (which I only just fell over this evening so will have a lot of catching up to do by the looks of it )
Hi , very interesting, cork tiles were all the rage back in the 1960,s on floors in block of flats and houses , and yes when empty they always felt a little warmer , when empty before the people moved in .
Did you get hands on with the seacork decking sheets? I wonder how they compare to the spray? Do you think the spray would hold up as an exterior decking, or is the sheet/plank material fundamentally different somehow? Also, I wonder if you have weight or density specs, if it's on the seacork website then I couldn't find it.
Hey, I don’t think you will get those specs from Seacork bug give them a call - they are sure helpful. It’s fairly durable, but not enough for a deck that’s for certain. The decking is pressed and bonded under pressure and steam. It’s completely different. The spray cork comes in 12kg pots of which I believe around 75% will evaporate as it cures. We used 9 buckets for 3 layers inside our van. (A Lwb High to Crafter - Don’t forget the roof and windows were not done though)
Thats really interesting stuff! Micro pores right? I will need to learn more to be honest but it’s super interesting… may need to do some testing there too! Cheers 👍
@@SailHub yea nanometer sized pores filled with air so it's light weight as well. I'm not a fan of permanent foam. Aerogel panels have the potential to be the best insulation for boats. Really want to try them. Also look into vibration damping tape this reduces sound from vibrations. The only downside of these is going to be the price.
@@SailHub should first get a thermal camera. Being able to quantify the current thermal performance and find the weakest zones is wizardry. You could save money if addressing the worst parts was all you needed. Verifing your insulation actually works afterwards is also nice, might have missed a spot. Plus thermal cameras are just cool that's enough reason to get one.
@XArthieX your right! We should! I’m game for anything like that.. such a geek 😂 we used one years back for tracking leaks in wooden boats - I could track the water up the planks and it was awesome. There’s more testing coming soon, let’s see if we can afford a camera, the prices are INSANE!
I always thought about filling the hollowspace with cork granulate. It will settle over time into every cravice and then you can refill it from the top.
Sounds simple enough, we’ve actually done that behind the fridge in the van. As it’s open to air for the vent I decided if may get a bit damp at times and the large surface area of granules could help it evaporate easier?!
Would be interesting to do a side by side comparison with a similar van but with no insulation. And another one with a different (typical insulation like foam spray or PIR boards) and do sound tests from inside and outside. Like decibel wise. That way we would better understand how well this setup performs from a soundproofing point of view. Having said that, I never knew that this cork spray (paint) was a thing. And I am considering just ditching the whole insulation, and instead soundproof the van. Since like you stated the insulation of the cork isn't bad either (and sheep wool).
Hi, yeah that would be fab! I can tell you the difference from an uninsulated van has been amazing. It’s a shame we can’t compare the decibels but I may find a way yet as my brother has a traditionally insulated sprinter. I guess it’s just finding a sound meter to borrow..we could do this with a mic and show the results in our post processing software but I’m sure people will say it’s been rigged. I will think on this one.
@@SailHub Yes, a decibel meter would be better, along with the sound comparison side by side in the UA-cam video. I am currently working on layout and wiring etc before I need to pull the plug on the insulation so I will try to wait for the video. But this method looks great. Thanks guys! ♥️
@renstillmann I would crack on if you want a video as we have a lot on our plate. Check out our website and feel free to send us an email through the contact us page. I can happily sort a call out to let you know what we know in a more sensible time frame.
So the question is how waterproof is the spray cork? Is the glue toxic in any way, and does it break down ? Is it easily removed in case of rust or repairs needed? Love the idea, love wood based products, so very interested. I have a 1972 VW Transporter that would benefit greatly from a product like this, but worried about rust.
Hey! You’d have to talk to SeaCork as I’m not going to take responsibility for this! Mind you, I understand it’s fine for all of your worries, I asked them all too. It’s also super common on mental boats where these same issues are also there, just with greater cost implications and it’s often regarded as the best option. Hope this helps, cheers
@@SailHub Those cork sheets looked like they crumbled SO easy. I'm also rebuilding an aluminum boat (Canada) and trying to find an alternative to sprayfoam. It currently has 80's fiberglass insulation bonded to some kind of 5mm board with aluminum foil on the cabin-facing side
@jeffd7976 sounds like an interesting project! The cork board, yeah, it’s male cork and it’s pretty crumbly. When it’s in it’s not messy though. Mind you it’s not all that light and it’s not generally used on boats, we’re mainly using it for its sound insulation properties given the van is to be a podcast suite.
1. What's the R value? 2. Is the cork "open cell" and does it absorb water? 3. Is it flammable? 4. How much heavier is it than closed cell foam? Thanks!!!
Hey, you would need to find out about U values and yourself. We can’t find all the info. The cork is pretty danned fire proof and is closed cell to our testing though. We are found some testing. Weight, not sure to be honest, I would guess heavier. But then you don’t need sound deadening or carpeting etc.
Would have been good to see the finished job inside the van. Also a breakdown of costs would be useful. I've been looking into cork insulation and have found it very expensive compared to other forms of insulation. I love the finish of cork thought hat has significant advantage over other insulation. Would be good to fins out what you spent.
Hey, It’s all dependant in where you are and why you want. I will add this to an upcoming video where we test the cork for you. I’m short, it was €190 per cork bucket:m. We used 10. That was for sufficient to do the van for the arctic as we are testing it to see if it’s good enough for our boatbuild that we are taking up there. You could generally get away with 1/2 to 2/3 of what we used. It is expensive but you do gain in areas; there is no need for sound deadening and there is no need to line the walls with anything such as carpet etc. Another note is that we used a marine based product, ‘Seacork’ it’s expensive as it’s developed for the humid marine environment, there are much cheaper options out there with similar insulation benefits however the overall performance (longevity, mold resistance etc) is generally reduced. Hope this helps. Cheers 👌
Excellent video, insulation is a major issue for yachts, seriously major and one that I've been researching for quite a while without success. You have solved this perfectly. Thank you!
@@SailHub You deserve the gratitude. I'm not sure if you realise all the issues you solved. It was brilliant! We are designing and building a largish trimaran to be constructed using carbon fibre. Which you must know has a "booming" issue in choppy to rough seas. Also there's a conductive issue. The spray cork solves both these issues, the sheet cork between ribs in living/social areas solves both noise and temperature issues very well. Then the wool fibre is pure genius for those hard to insulate internal and external corners. Then the added bonus is the spray cork uses a water based "adhesive" meaning less toxic smoke in case of a fire giving you extra time to fight it. It's the best solution by far that I have seen. So thank you very much! 🍻🍻
@user-hv8ir2ef6r ah, cool. So pleased it was useful for you! There is another thing worth looking at too, aerogel. Not sure if it is financially sensible yet but it is mind blowing!
We used 10 buckets, I think there’s are 12kg each?! Mind you we did 4 coats which is enough to live in through a northern Scottish winter. I believe the usual is 3 coats.
@@SailHub thank you for posting the video ! Not really into boats or campers but always technical curiosities call my attention. Your info was clear and entertaining !
😂 maybe… but does it really make ay sense to most people anyway? I mean, what does 2.5db or 20db reduction mean to the average sailor? I rekon a nocking stick works just fine?!
Hey Daniel, thanks mate. Thanks for the feedback too, much appreciated. Our next video is up this evening at 6… I think we’re getting better with sound levels, it would be great to hear your thoughts.
Hey James, so far it seems ridiculously robust. I suppose we’ve just got to look at a cork stopper, they kick around for years and not much happens to them.
Cork gets moldy in a damp and dark corner. I have 5yrs liveaboard experience in cool climate; Armaflex closed cell sheet is the thing. Stays clean and dry.
I can see your ponts for sure. Mind you are you taking sprayed cork here? If you are how much of it is there? It sounds like there is not enough. We’ve met many boats now that have been around the world without trouble and it’s also the go too for arctic vessels (hence our interest). The ones that have had any condensation have had to little thickness. When topped up to a hood thickness the problem goes away. As for the armaflex, it is great but I’d have to do some tests, I would actually really like to do some testing on it, at the end of the day we’re just looking to inform people of their options and we can only recommend what we can personally trust. So cheers, here to hoping we can test some sometime 👍👌
I made a Sandwich of wood and cork for my campervan floor. 9mm Each side of 19mm queenly. With natural ventilation underneath. Did the sides with 6mm of a roll. And 60mm recycled PET. Thought off spraying. Just, it's so messy.
Sounds fab. It all makes sense, I guess your just missing out on the sprayed ‘skin’ that prevents any condensation on the metal where boards and the likes don’t touch. Small price to pay and a lot cleaner than the spraying like you say.
I have been wondering how cork would perform on a vehicle like a van. Use of cork on houses have been on the rise where I am, and I was always curious when someone would spray a vehicle
So far it’s been fab! But then we’ve not had a winter in Germany to take notes. As soon as we’re out in the finished van we will be in doing some winter testing in the Swiss Alps! Stay tuned…
Yeah, I would agree it seems good for both. Ballast is a big factor in boats, as specified design weight. Ideally we don’t want to add much weight if possible and if we want extra ballast we can add more useful things of greater weight such as tools and spares etc.
feeling the temperature is same as standing on tile floor in bathroom with or without slippers.. Temperature is in both cases same but bare feet "feel" colder due to heat extraction/conductivity..
@paulsinclair3401 sure. We used 11 pots of Seacork in total. We could have done 10 easily as we cut more of the roof out than expected. We also are only cutting out two windows so there’s a lot used there which many people would not need. Second to that we put 4 layers in there as we are testing it for arctic cold climates that we are building the boat for. I belive 2 coats is common for vans. Price is relatively high at around €190 euro per pot when we bought it, the pigment was super cheap but I can’t temember exactly. I suppose the good thing for us is that we don’t need acoustic insulation too as the van is a podcasting suite.
@@SailHub do you have an update on long-term of this Cork insulation?? I am looking for tiny home, RV, shipping container and semi trailer conversions...our primary concerns are: 1. Mold 2. Toxic off gassing 3. Longevity 4. Duration of resistance to termites, ants, etc...
Hey, we’ve going to make a video after the next winter so we actually have some good data. To answer your questions sheets I can though; Mold, cork naturally inhibits this and it prevents the due point and therefore no moisture means no mold. There are people who say that they have experienced mild but when I have seen their installation, there is too thin a layer of material and this not enough insulation. 2. Toxic gassing, I’ve not got a gas meter of sorts but I am told by SeaCork that their product is organic and there is nothing toxic. 3. The longevity seems to be fantastic. There has been many boats using SeaCork for arctic expedition for well over 10 years without trouble. 4. Termites, I have no clue, sorry. The only thing I can say is the manufacturer stated it was no problem and we received a comment from an architect who suggested they used a similar product in their housing designs as it was resistant to termites. I am personally not sure at all but I would live to see some testing on this! Hope this helps!
Yeah, the flickering was a real shame. It wasn’t like that on our computers editing software so I’ve no idea what happened there. It’s mega annoying! 😆 As for the sound, what can I say, we’re getting better!
@noah786 yeah it’s pretty cool although it ones tracks the dust. That’s being said we have ends it flat in part of our van build so we will show that soon. It works quite well
Interesting product, not come across spray cork. Is it vapour permeable? I guess it must be, as applied wet, once it dries it will leave pores. If so moisture will build up, though the cork is naturally mould resistant, whatever it is fixed to is a possible issue. Cork board is know has a much lower insulation value to the plastic foams. So if overall heat loss is important perhaps not best. But just for condensation maybe. I don’t think there is a really closed cell spray foam, I have never come across one. Most are polyurethane, they definitely aren’t, well certainly after a few years…and hell to remove. I would be very wary of any spray product below waterline or where water could collect. If you are mainly in a cold damp climate, all these products that do absorb some moisture should not be used. If only for short periods of time, they can absorb a bit then dry out. (The same for building flat roof insulation, which I do know about)
Hi Mark, a lot off hood points there of which we will need to contact the manufacturer about, we are doing some testing at present ourselves so stay tuned to see what we find. As for water absorbing. I belive it’s lded good, it’s commonly found below waterline on boats such as the Garcia exploration etc. I’m told it doesn’t take on water which sounds great. There appears to be no U value present but the difference in our van was to be quite honest, unbelievable. We were very impressed. The sound deadening is also exceptional, so let’s see what we can test and find out!
@markthomasson5077 right, that kinda makes sense but I also think it’s a problem I’m done areas. I.e fridge insulation is often crap based on the sand theory and they then remain the biggest electrical consumer onboard. Mind you, as a generalisation I rekon your bang on👍
Sorry my friend, if we had the budget for it that’s exactly what we would do. Maybe we could have done it with a phone but then we would get comments stating it’s not valid… where do we go with that? Anyhow, we’re gonna do a follow up after the or part way through the winter based on what we think so far. Do you think we should do it with a phone or not?
@@SailHub Any type of comparison measurement would be appreciated. I am planning on soundproofing my bedroom wall, was thinking about using 1/4" cork sheets between sheets of drywall as a vibration dampener. What do you think?
@JP5466 sounds good, I know some friends who used similar on a moody 44 yacht to sound insulate an office room to work from home. It worked a treat! I will pop some comparisons in the overview video in some way or form for you 👍
I can see your thought process for sure. The cork is like a skin, so in theory it should stop damp getting in. I’m pretty happy with it and I’m aware that steel boat builders use it too, which has to be a worse situation than a van or a car on the roads. Anyhow, that’s my 2 cents 👍
It does not last, cork sheet or granules break down over time. Many villas in Portugal have it and if you open a hole in the middle of the wall the cork has dropped down so no value above maybe a metre height.........and that is where you need insulation.
Really? I’m not so sure about that. Cork granulated breaks down when encapsulated by a waterproof membrane. Let’s not forget this is a marine product here, not a housing product. I’m aware of the types of product you are talking about but this is different.
@CarlosAlberto-ii1li hey up chap, It’s Seacork, as ne roomed in the video. Now, we’re all up for honesty and that’s what our channel is built on. Just I think it harsh to slam a product if you’ve not used it and also wrong to suggest it’s the same as a domestic product. There’s a lot of R&D gone into this, I just don’t want to reduce their sales based on false knowledge. I hope you understand.
Thats all rainbows and unicorns until ..... a panelbeater has to try and fix it, how do you find spot welds and drill them out to separate panels for replacement, I can't imagine a better way to conceal spot welds ever.
😂unicorns aren’t real! In all seriousness it appears It peels off if you need access. We found that when cutting up the roof for the poptop instalation.
@@SailHub Haha ! I haven't tried it yet due to a lack in any apartment (browsing endlessly for the optimal boat)... But I remember that ready made concrete 'council flats' had as much sound isolation as a mini van... The cork layer may also help with unheated walls where moisture condensates and forms mold - cork wallpapers or sheets used to be a practice, I think - but an evenly sprayed and even colored cork coat may be more thorough.
@@SailHub I am supportive. It is a way to improve your videos. You do quite well in other areas. Like you never use the word "what" as a filler instead of for asking a question. None of the "What this does is it...." or "What you wanna do now is you wanna.." that litters so much DIY video.
@charlesspringer4709 ok, I will bear that in mind. We’re all up for constructive criticism it’s just not that pleasant when it comes across as more of a rant with non positive word alongside them. Cheers, we will work on it 👍
Yup. Mind you you still get a few point with most foams and they often wick water which isn’t great either. Oh, and you don’t need sound deadening or carpeting so the finished product is not 3x the cost, which is at least one thing! As sad as it is, most environmentally friendly products do come with an added cost, usually due to the small sales quantities, I guess we can hope it gets better. One last point, where do you get your data from, I’m interested in the 1/3 performance. From my understanding I would actually suggest it could be better than foam, we’re doing some testing soon so we will find out I guess!
@jwstout007 hahah! Now I get it! You see I’m just not that well educated about fine wines and the likes. Welders, saws and boats though…. Ohhhhh yeaaaah!
It must have a lot of chemicals added to it to be sprayable. Cork does not just stick to things, as if compressed only, it will easily break. That thing seems like ESG box ticking bs
It’s a water based bonding agent with it. I imagine you could find the details if you search, being CE approved it should be there for all to see Let’s not forget it’s a hopper gun too. Hardly a fine mist. There is a 6mm hole in the end of the gun!
Orange boat?! Ahh you mean Odd’s boat? Obviously that’s not ours but they sold up to build a new one. 👍 We’re like twin channels, Sail hub and Odd life, both building a camper van and both building a boat!
Yup, I can see why this comes to mind, it did me too. The thing is, it uses a different method. You can see that we taped up all of the holes in the structure and sprayed over it. There is complete skin around the inside of the van, so we don’t need to fill the gaps.
Late comment because I’ve just watched the episode = so at least a tiny bit of logic obviously need glasses to see it or should it be sea it , whoops humour not required, sorry digress on steroids, looking at the cork spray thought about why it’s not used on concrete floors for insulation from the cold , thinking this because the having concrete floors myself definitely feel the cold coming from the especially in winter here in the UK, crazy thought maybe , take care guys = me .
Hey Kavan, Thank ls for your comment fella, yeah we’re no dude why either. It could be due to the entrapment of moisture in the concrete as it’s porous. Mind you, it was originally developed for insulation of house walls so maybe you could try it? Corksol would be your suppliers and installers to call in the UK 👍 If you do it let us k own how you get on mind!!
Bizarre strobing light flashes and loud rock music making hearing the narration difficult is a guaranteed way to alienate viewers. As interested as I was in these forns of insulation, I don't want to be subjected to strobing light flashes and loud rock music drowning out narration. I will obtain information from a credible source rather than this unfocused one.
You do that my friend. We really don’t need feedback from people in a rude manner anyhow. We prefer genuine people who want to help us grow in pleasurable way. Theres really no reason to be rude.
@@SailHub Your unfocussed presentation of strobing light flashes and loud rock music played over your narration undermines your channel credibily as it negatively affects the video. This is objective criticism, not rudeness! Perhaps consider the points I made rather than your easily hurt feelings. I wasn't the only viewer to point out the strobing light flashes.
Thanks for your clarity here. We value supportive criticism for sure! And we’re always trying to improve on this. We hope you find some value in our other/future videos 👍🏼
@@SailHub That was slightly tongue in cheek. I suspect that cork that's been shredded, then reconstituted probably won't explode. It's the air trapped inside raw natural cork that goes pop when heated.
Can’t imagine it from raw cork. Maybe alcohol impregnated variants. The thing is, cork trees we’ve seen in bush fires are the only thing that survive and the cork is still harvestable.
Coming From Odd Life Crafting. You guys truly did amazing content as well. Really Enjoyable.

Thanks, let’s see how it goes! We have some interesting testing coming up too. We wanted to try before we put it on a boat, there some other options we are looking into as well although I’m not sure they are available as a product yeti.
Could be the right stuff. I covered my catamaran with cork tiles and keep it in Florida. Termites ate it up, had to tear it all out.
@lewisoverdorp8405 termites, yeah I can imagine they could be a problem. I would love to know more about spray cork and termites, we’re looking at spraying our new hull but you’ve got us thinking now!
@@kenf1445 I'm trying to load some pictures, can't figure it out.
I'm Portuguese and my grandma had a cork farm.
We brought boxes of tiles back to Florida in our suitcases and thought that would do the trick.
Then I was absent for a few years and got termite infested. 50' Prout , solid fiberglass. She had partially sunk from a previous storm so I had to rip out the original vinyl backed foam.
Glued the cork directly on the glass and wood walls. Worked great for the sweating but the termites devoured the cork. I never thought they'd eat the glued cork tiles.
Perhaps when you spray, you can add diatomaceous earth to the mix.
Id try it out on a piece of wood and throw it on some termite hill for an experiment first.
@lewisoverdorp8405 hey Lewis, thanks fella! That’s superb advice! We’re thinking about insulating the boat and termites have quickly become a concern! Diatomaceous you say 👍👌
Darn it! UA-cam recommended this video from 9 months ago and it's full of great info, well presented and interesting. Looks like I'll have to watch your whole back catalogue to make sure I haven't missed anything. I'll be back in 90 days or so when I'm done 😇😂
😂 Thanks Wagner! Glad you enjoyed it 👍
Love your work - we sailed the Indian Ocean in a steel boat - it had 3 inches of fire retardant polystyrene insulation in deck to water line - cool as a cucumber.. upgraded to an HR - closed cell foam core - but with a teak deck in Greece in summer - it was as hot as hell - do not know how it will go in Scotland in winter with condensation...
Ooooh, that’s sounds fun!
So which HR have you got? The first cored ones. We’re the 382 and the 352, they were pretty good, when they changed to davinicell foam things got better - I can confirm a Najad from 2000 is fantastic in a Scottish winter! (They use the same techniques as HR)
Cheers for the compliment too!! 👍🤟
@@SailHub HR 43 - 2003..we want to do Ireland the Outer Hebrides - Shetland and winter in Scotland.
@@DirkJacobsz sweet, we did that a few times, give us a shout if you need help planning the trip - check out Erik from NBJS who recently did it too 👍

I have been wondering about spraying cork in my camper for years, but the only one I could find was 'corksol' and you have to do their course so you can buy the stuff!
Thanks for this, I will now have a look at 'sea cork'
Will deffo check some of your other vids 😊
Hi! Thanks for your comment, yeah corksol I belive can be trick to work with. If you get stuck send us an email and we will try to help 👍
Chris - this is really cool - sailed the Indian Ocean in a steel boat with 25mm polystyrene insulation -it was cool as a cucumber - now have an HR with closed cell - sailing in the Med - and it is as hot as hell - an oven in here. So cork sounds good to me. great stuff.
Hey Dirk, the Med is HOT! yeah, the cork is looking like our choice for the boat build however there is another option we’re looking into which I think is better again… just the cost to figure out though. Aerogel…. Seems to good to be true!
Btw, sounds like you’ve done some amazing sailing fella!!
@@SailHub Chris - still have to hit you up for advice on Scotland - heading there next year - if we can get past the Orca's..
I like his Safe-Tea glasses!
😂 love it 👍
On the subject of that flax fibre boat you were stood next to at the trade show. I absolutely adore that look and have been wanting to try and bring that into my interior van furniture design ever since I saw the easy composites channel make that canoe with it.... Do you have any thoughts as to how in the hell I make composite cupboards work in my van build as I'm struggling to think of how to implement it
Sure man, there’s a ton of ways. We will be doing some of that in the boat. Question is, do you want to mould them, buy sheet material or make your own sheets? SaMe for corner mouldings? Mould your own or buy them?
What’s your thoughts?
@@SailHub After trying to figure out how to to mould the cupboard, curved corners and everything, I couldn't really get my head round how to make them that way so that they had enough ribs and general structure to hang the doors and runners off of, so my brain sort of copped out and said perhaps it would be easier just to capture flat panels of the stuff in a normal wood frame... Undecided really but would love to figure out how to make the entire curved cupboard in one seamless structure, much like the wood veneer in your current van build (which I only just fell over this evening so will have a lot of catching up to do by the looks of it )
❤️🔥Great shout on the Cork and sheep's wool van insulation. I'll be looking into that for a future build for sure. Thanks 🤙🤙
Cool, glad you approve! We will be testing it soon so stay tuned for the results! Cheers for commenting too! 🤟🏼
Hi , very interesting, cork tiles were all the rage back in the 1960,s on floors in block of flats and houses , and yes when empty they always felt a little warmer , when empty before the people moved in .
Yeah, our fiend rhys from the YT channel sailing yacht Zora has old school cork tiles on the floor of his boat. They’ve worked a treat for him👍
Cork insulation is Brilliant for a lot of interior insulation tasks.
Couldn’t agree more. I believe it’s used for a lot of houses externally too in Europe 👍🏼
Did you get hands on with the seacork decking sheets? I wonder how they compare to the spray? Do you think the spray would hold up as an exterior decking, or is the sheet/plank material fundamentally different somehow? Also, I wonder if you have weight or density specs, if it's on the seacork website then I couldn't find it.
Hey, I don’t think you will get those specs from Seacork bug give them a call - they are sure helpful.
It’s fairly durable, but not enough for a deck that’s for certain. The decking is pressed and bonded under pressure and steam. It’s completely different.
The spray cork comes in 12kg pots of which I believe around 75% will evaporate as it cures. We used 9 buckets for 3 layers inside our van. (A Lwb High to Crafter - Don’t forget the roof and windows were not done though)
@@SailHubGreat info, thanks!
@@SailHubWondering why you didn't spray the roof? Would it not be better for soundproofing to spray the ceiling?
@renstillmann ah, simple! We are cutting the roof out and replacing it with an elevating roof.
Did not know about spray cork. Bought some thin sheets of cork and put it in my Camper Van a couple years ago. Mostly for sound
Cool, how did it work out for you?
@@SailHub It works great for the Van and to soften sound of walking and the road.
@prophetseven728 well, thats a winner then 👍😃
Coool! And in Mediterranean Spain, Nice property!
Yeah, what a cool spot! We spend a lot of time in the EU dining, this year we’re concentrating on the UK a bit more, can’t wait!
love the content guys ,, might cork my shed
😂 megashed! I’ve got a sweet recipe for you matey, we’ve been working on it…
I want to try aerogel insulation. It's fireproof, great with moisture. Good sound and heat insulation.
Thats really interesting stuff! Micro pores right? I will need to learn more to be honest but it’s super interesting… may need to do some testing there too! Cheers 👍
@@SailHub yea nanometer sized pores filled with air so it's light weight as well. I'm not a fan of permanent foam. Aerogel panels have the potential to be the best insulation for boats. Really want to try them. Also look into vibration damping tape this reduces sound from vibrations. The only downside of these is going to be the price.
@XArthieX sure, price… that’s always an issue but the tech sounds amazing… hmmm…🤔
@@SailHub should first get a thermal camera. Being able to quantify the current thermal performance and find the weakest zones is wizardry. You could save money if addressing the worst parts was all you needed. Verifing your insulation actually works afterwards is also nice, might have missed a spot. Plus thermal cameras are just cool that's enough reason to get one.
@XArthieX your right! We should! I’m game for anything like that.. such a geek 😂 we used one years back for tracking leaks in wooden boats - I could track the water up the planks and it was awesome.
There’s more testing coming soon, let’s see if we can afford a camera, the prices are INSANE!
I always thought about filling the hollowspace with cork granulate. It will settle over time into every cravice and then you can refill it from the top.
Sounds simple enough, we’ve actually done that behind the fridge in the van. As it’s open to air for the vent I decided if may get a bit damp at times and the large surface area of granules could help it evaporate easier?!
Would be interesting to do a side by side comparison with a similar van but with no insulation. And another one with a different (typical insulation like foam spray or PIR boards) and do sound tests from inside and outside. Like decibel wise. That way we would better understand how well this setup performs from a soundproofing point of view.
Having said that, I never knew that this cork spray (paint) was a thing. And I am considering just ditching the whole insulation, and instead soundproof the van. Since like you stated the insulation of the cork isn't bad either (and sheep wool).
Hi, yeah that would be fab! I can tell you the difference from an uninsulated van has been amazing. It’s a shame we can’t compare the decibels but I may find a way yet as my brother has a traditionally insulated sprinter. I guess it’s just finding a sound meter to borrow..we could do this with a mic and show the results in our post processing software but I’m sure people will say it’s been rigged. I will think on this one.
@@SailHub Yes, a decibel meter would be better, along with the sound comparison side by side in the UA-cam video.
I am currently working on layout and wiring etc before I need to pull the plug on the insulation so I will try to wait for the video. But this method looks great. Thanks guys! ♥️
@renstillmann I would crack on if you want a video as we have a lot on our plate. Check out our website and feel free to send us an email through the contact us page. I can happily sort a call out to let you know what we know in a more sensible time frame.
So the question is how waterproof is the spray cork? Is the glue toxic in any way, and does it break down ? Is it easily removed in case of rust or repairs needed? Love the idea, love wood based products, so very interested. I have a 1972 VW Transporter that would benefit greatly from a product like this, but worried about rust.
Hey! You’d have to talk to SeaCork as I’m not going to take responsibility for this!
Mind you, I understand it’s fine for all of your worries, I asked them all too.
It’s also super common on mental boats where these same issues are also there, just with greater cost implications and it’s often regarded as the best option.
Hope this helps, cheers
VERY interested in seeing a followup on this one. I wonder how spray cork under unbonded foam sheets would fare
Sure! We’re working on it!
I don’t think you would need the foam to be honest.. but we will hopefully find out in some upcoming tests! 👍😀
@@SailHub Those cork sheets looked like they crumbled SO easy. I'm
also rebuilding an aluminum boat (Canada) and trying to find an alternative to sprayfoam. It currently has 80's fiberglass insulation bonded to some kind of 5mm board with aluminum foil on the cabin-facing side
@jeffd7976 sounds like an interesting project!
The cork board, yeah, it’s male cork and it’s pretty crumbly. When it’s in it’s not messy though. Mind you it’s not all that light and it’s not generally used on boats, we’re mainly using it for its sound insulation properties given the van is to be a podcast suite.
Cork seem like an alternative under sleeping bed cushions on sailboats as well.
Sure, why not?!
1. What's the R value?
2. Is the cork "open cell" and does it absorb water?
3. Is it flammable?
4. How much heavier is it than closed cell foam?
Thanks!!!
Hey, you would need to find out about U values and yourself. We can’t find all the info.
The cork is pretty danned fire proof and is closed cell to our testing though. We are found some testing. Weight, not sure to be honest, I would guess heavier. But then you don’t need sound deadening or carpeting etc.
Would have been good to see the finished job inside the van. Also a breakdown of costs would be useful. I've been looking into cork insulation and have found it very expensive compared to other forms of insulation. I love the finish of cork thought hat has significant advantage over other insulation. Would be good to fins out what you spent.
Hey, It’s all dependant in where you are and why you want. I will add this to an upcoming video where we test the cork for you.
I’m short, it was €190 per cork bucket:m. We used 10. That was for sufficient to do the van for the arctic as we are testing it to see if it’s good enough for our boatbuild that we are taking up there. You could generally get away with 1/2 to 2/3 of what we used.
It is expensive but you do gain in areas; there is no need for sound deadening and there is no need to line the walls with anything such as carpet etc.
Another note is that we used a marine based product, ‘Seacork’ it’s expensive as it’s developed for the humid marine environment, there are much cheaper options out there with similar insulation benefits however the overall performance (longevity, mold resistance etc) is generally reduced.
Hope this helps. Cheers 👌
Excellent video, insulation is a major issue for yachts, seriously major and one that I've been researching for quite a while without success.
You have solved this perfectly. Thank you!
Oh wow, thanks. We’re glad you enjoyed it 👍
@@SailHub You deserve the gratitude. I'm not sure if you realise all the issues you solved. It was brilliant!
We are designing and building a largish trimaran to be constructed using carbon fibre. Which you must know has a "booming" issue in choppy to rough seas. Also there's a conductive issue.
The spray cork solves both these issues, the sheet cork between ribs in living/social areas solves both noise and temperature issues very well. Then the wool fibre is pure genius for those hard to insulate internal and external corners.
Then the added bonus is the spray cork uses a water based "adhesive" meaning less toxic smoke in case of a fire giving you extra time to fight it.
It's the best solution by far that I have seen.
So thank you very much! 🍻🍻
@user-hv8ir2ef6r ah, cool. So pleased it was useful for you! There is another thing worth looking at too, aerogel. Not sure if it is financially sensible yet but it is mind blowing!
@@SailHub Thanks for that, I'm heading straight to Google now! Hahaha
@user-hv8ir2ef6r great stuff👍
How many kgs of the seacork mix did you use for all the coats?
We used 10 buckets, I think there’s are 12kg each?!
Mind you we did 4 coats which is enough to live in through a northern Scottish winter. I believe the usual is 3 coats.
Great video . Thank you for the all the info .
Hey David! Thanks fella 👍
@@SailHub thank you for posting the video ! Not really into boats or campers but always technical curiosities call my attention.
Your info was clear and entertaining !
For some reason I thought before/after sound tests would involve a dB meter for a video making crew.
😂 maybe… but does it really make ay sense to most people anyway? I mean, what does 2.5db or 20db reduction mean to the average sailor? I rekon a nocking stick works just fine?!
I've never seen Duca so quite! 🤣🤣🤣❤❤
😂 I’ve never seen him quiet! What a legend 👍❤️
Thanks for the tips.Great informative video. BTW music covering up the voice too often...
Hey Daniel, thanks mate.
Thanks for the feedback too, much appreciated.
Our next video is up this evening at 6… I think we’re getting better with sound levels, it would be great to hear your thoughts.
how does cork hold up in general? understand its positive traits, but how about durability, given that its an organic material?
Hey James, so far it seems ridiculously robust. I suppose we’ve just got to look at a cork stopper, they kick around for years and not much happens to them.
Cork gets moldy in a damp and dark corner. I have 5yrs liveaboard experience in cool climate; Armaflex closed cell sheet is the thing. Stays clean and dry.
I can see your ponts for sure. Mind you are you taking sprayed cork here? If you are how much of it is there? It sounds like there is not enough.
We’ve met many boats now that have been around the world without trouble and it’s also the go too for arctic vessels (hence our interest). The ones that have had any condensation have had to little thickness. When topped up to a hood thickness the problem goes away.
As for the armaflex, it is great but I’d have to do some tests, I would actually really like to do some testing on it, at the end of the day we’re just looking to inform people of their options and we can only recommend what we can personally trust. So cheers, here to hoping we can test some sometime 👍👌
I made a Sandwich of wood and cork for my campervan floor. 9mm Each side of 19mm queenly. With natural ventilation underneath.
Did the sides with 6mm of a roll. And 60mm recycled PET.
Thought off spraying. Just, it's so messy.
Sounds fab. It all makes sense, I guess your just missing out on the sprayed ‘skin’ that prevents any condensation on the metal where boards and the likes don’t touch. Small price to pay and a lot cleaner than the spraying like you say.
I have been wondering how cork would perform on a vehicle like a van. Use of cork on houses have been on the rise where I am, and I was always curious when someone would spray a vehicle
So far it’s been fab! But then we’ve not had a winter in Germany to take notes. As soon as we’re out in the finished van we will be in doing some winter testing in the Swiss Alps! Stay tuned…
I feel the weight to thermal and space ratio of cork arent greatly suited to a van. Boats sure as they need 'ballast' to keep stable..?
Yeah, I would agree it seems good for both. Ballast is a big factor in boats, as specified design weight. Ideally we don’t want to add much weight if possible and if we want extra ballast we can add more useful things of greater weight such as tools and spares etc.
feeling the temperature is same as standing on tile floor in bathroom with or without slippers.. Temperature is in both cases same but bare feet "feel" colder due to heat extraction/conductivity..
Exactly, we can feel that the cork is not a heat sink. 👍
Can 4 way stretch headlining be applied over the sprayed cork insulation? If yes it will change the direction of the projrct I am working on.
Oooh, what’s the fabric? I presume you will need a backing of sorts due to the texture of the cork?
Did I miss a breakdown of the total cost of insulating the van with cork? It would be helpful?
You did! It massively depends on the brand of cork and of course the size of the van hence why we didn’t go into it.
@@SailHub - Yes, but as we can see both the size of your van and you specified the cork you used, it would give us a general idea of cost?
@paulsinclair3401 sure. We used 11 pots of Seacork in total. We could have done 10 easily as we cut more of the roof out than expected. We also are only cutting out two windows so there’s a lot used there which many people would not need.
Second to that we put 4 layers in there as we are testing it for arctic cold climates that we are building the boat for. I belive 2 coats is common for vans.
Price is relatively high at around €190 euro per pot when we bought it, the pigment was super cheap but I can’t temember exactly. I suppose the good thing for us is that we don’t need acoustic insulation too as the van is a podcasting suite.
@@SailHub - Many thanks for that...... gives me a general idea. 👍👍
@paulsinclair3401 no problem chap 👍
actually is great for a boat as cork is bouyant
Love it! Never even thought 😁
Camera effect taking pictures at 228 is absolutely annoying. I skipped this part, I wonder how many just turned it off or moved on
How weird! It seems to be flickering - it didn’t do that previously!
@@SailHub do you have an update on long-term of this Cork insulation?? I am looking for tiny home, RV, shipping container and semi trailer conversions...our primary concerns are:
1. Mold
2. Toxic off gassing
3. Longevity
4. Duration of resistance to termites, ants, etc...
Hey, we’ve going to make a video after the next winter so we actually have some good data.
To answer your questions sheets I can though;
Mold, cork naturally inhibits this and it prevents the due point and therefore no moisture means no mold. There are people who say that they have experienced mild but when I have seen their installation, there is too thin a layer of material and this not enough insulation.
2. Toxic gassing, I’ve not got a gas meter of sorts but I am told by SeaCork that their product is organic and there is nothing toxic.
3. The longevity seems to be fantastic. There has been many boats using SeaCork for arctic expedition for well over 10 years without trouble.
4. Termites, I have no clue, sorry. The only thing I can say is the manufacturer stated it was no problem and we received a comment from an architect who suggested they used a similar product in their housing designs as it was resistant to termites. I am personally not sure at all but I would live to see some testing on this!
Hope this helps!
I agree. Also the 'background' music making the speech inaudible.
Unfortunately I gave up watching around half way through. Shame.
Yeah, the flickering was a real shame. It wasn’t like that on our computers editing software so I’ve no idea what happened there. It’s mega annoying! 😆
As for the sound, what can I say, we’re getting better!
How many coats did you end up spraying?
We did 4, our friends did 3. We were told 2 is enough for the Med and 4 for northern scotland.
@@SailHub Thanks for sharing.. I like the way it looks as a finished surface for all of the rounded metal corners and doors.
@noah786 yeah it’s pretty cool although it ones tracks the dust. That’s being said we have ends it flat in part of our van build so we will show that soon. It works quite well
Interesting product, not come across spray cork. Is it vapour permeable? I guess it must be, as applied wet, once it dries it will leave pores. If so moisture will build up, though the cork is naturally mould resistant, whatever it is fixed to is a possible issue.
Cork board is know has a much lower insulation value to the plastic foams. So if overall heat loss is important perhaps not best. But just for condensation maybe.
I don’t think there is a really closed cell spray foam, I have never come across one. Most are polyurethane, they definitely aren’t, well certainly after a few years…and hell to remove.
I would be very wary of any spray product below waterline or where water could collect.
If you are mainly in a cold damp climate, all these products that do absorb some moisture should not be used. If only for short periods of time, they can absorb a bit then dry out. (The same for building flat roof insulation, which I do know about)
Hi Mark, a lot off hood points there of which we will need to contact the manufacturer about, we are doing some testing at present ourselves so stay tuned to see what we find.
As for water absorbing. I belive it’s lded good, it’s commonly found below waterline on boats such as the Garcia exploration etc. I’m told it doesn’t take on water which sounds great.
There appears to be no U value present but the difference in our van was to be quite honest, unbelievable. We were very impressed. The sound deadening is also exceptional, so let’s see what we can test and find out!
@@SailHub great.
In small spaces r values are not that important as they soon heat up. A house might need 30cm, whereas a boat / van 3cm
@markthomasson5077 right, that kinda makes sense but I also think it’s a problem I’m done areas. I.e fridge insulation is often crap based on the sand theory and they then remain the biggest electrical consumer onboard.
Mind you, as a generalisation I rekon your bang on👍
Fiberglass boat needs foil bubble insulation next to the hull and overhead to block solar radiation. After that insulator then upholstery foam.
Oh my goodness. That’s cave man talk! It works, but it’s hardly efficient. I would live to know where your confidence comes from in the modern world.
Flammability?
Well, I just blasted 130amps of tig welding through it and it smoulders a little but it won’t ignite. A further testing video will come soon 👍
I was hoping for a real sound db/transmission loss test, but you didn't do it.
Sorry my friend, if we had the budget for it that’s exactly what we would do. Maybe we could have done it with a phone but then we would get comments stating it’s not valid… where do we go with that?
Anyhow, we’re gonna do a follow up after the or part way through the winter based on what we think so far. Do you think we should do it with a phone or not?
@@SailHub Any type of comparison measurement would be appreciated. I am planning on soundproofing my bedroom wall, was thinking about using 1/4" cork sheets between sheets of drywall as a vibration dampener. What do you think?
@JP5466 sounds good, I know some friends who used similar on a moody 44 yacht to sound insulate an office room to work from home. It worked a treat! I will pop some comparisons in the overview video in some way or form for you 👍
Very enjoyable..
Cheers! Thanks for letting us know! 👍
If a deck doesn't have beams under it, it's cored.
Yup, but would also depend on the crown.
I think you mean in theory. I mean in actual boats. @@SailHub
?Interesting , however if you spray this on the inside of a metal yacht won't it hide corrosion & potentially be dangerous in that way?
I can see your thought process for sure. The cork is like a skin, so in theory it should stop damp getting in. I’m pretty happy with it and I’m aware that steel boat builders use it too, which has to be a worse situation than a van or a car on the roads. Anyhow, that’s my 2 cents 👍
@ 12:48 let's go check the comments. 😅
Exactly 😂😬
It does not last, cork sheet or granules break down over time. Many villas in Portugal have it and if you open a hole in the middle of the wall the cork has dropped down so no value above maybe a metre height.........and that is where you need insulation.
Really? I’m not so sure about that. Cork granulated breaks down when encapsulated by a waterproof membrane. Let’s not forget this is a marine product here, not a housing product. I’m aware of the types of product you are talking about but this is different.
@@SailHub I have been building in Portugal since 1988, it is just the knowledge I have. If you have a different cork then it's ok.
@CarlosAlberto-ii1li hey up chap, It’s Seacork, as ne roomed in the video.
Now, we’re all up for honesty and that’s what our channel is built on. Just I think it harsh to slam a product if you’ve not used it and also wrong to suggest it’s the same as a domestic product.
There’s a lot of R&D gone into this, I just don’t want to reduce their sales based on false knowledge. I hope you understand.
Thats all rainbows and unicorns until ..... a panelbeater has to try and fix it, how do you find spot welds and drill them out to separate panels for replacement, I can't imagine a better way to conceal spot welds ever.
😂unicorns aren’t real! In all seriousness it appears It peels off if you need access. We found that when cutting up the roof for the poptop instalation.
Nice
Cheers! We end some gear re-editing with it recently, should have it up soon.!
Spraying the stripped down walls of a concrete built apartment...
TREE HOUSE.
@christophmahler Amazing! I can imagine the difference must be outstanding?!
@@SailHub
Haha !
I haven't tried it yet due to a lack in any apartment (browsing endlessly for the optimal boat)...
But I remember that ready made concrete 'council flats' had as much sound isolation as a mini van...
The cork layer may also help with unheated walls where moisture condensates and forms mold - cork wallpapers or sheets used to be a practice, I think - but an evenly sprayed and even colored cork coat may be more thorough.
@christophmahler for sure, I think your right. The only downside is the rough texture but you can of course sand it flat or cover it
Please stop telling me what you are going to tell me! It is a 15 minute video, just tell me!
Hey Charles please stop telling me what you think if your not going to be supportive.
@@SailHub I am supportive. It is a way to improve your videos. You do quite well in other areas. Like you never use the word "what" as a filler instead of for asking a question. None of the "What this does is it...." or "What you wanna do now is you wanna.." that litters so much DIY video.
@charlesspringer4709 ok, I will bear that in mind. We’re all up for constructive criticism it’s just not that pleasant when it comes across as more of a rant with non positive word alongside them. Cheers, we will work on it 👍
wow you can get 1/3 the performance of spray foam for 3x the price.
Yup. Mind you you still get a few point with most foams and they often wick water which isn’t great either.
Oh, and you don’t need sound deadening or carpeting so the finished product is not 3x the cost, which is at least one thing!
As sad as it is, most environmentally friendly products do come with an added cost, usually due to the small sales quantities, I guess we can hope it gets better.
One last point, where do you get your data from, I’m interested in the 1/3 performance. From my understanding I would actually suggest it could be better than foam, we’re doing some testing soon so we will find out I guess!
14:50 the pros call it “cork sniffing” ;)
Your gonna have to help me out here… I’m a bit slow sometimes. 🤷♂️
@@SailHub wine reviewers / tasting afficionados are sometimes called cork sniffers. Just a little tongue & cheek in anticipation for your review :)
@jwstout007 hahah! Now I get it! You see I’m just not that well educated about fine wines and the likes.
Welders, saws and boats though…. Ohhhhh yeaaaah!
It must have a lot of chemicals added to it to be sprayable. Cork does not just stick to things, as if compressed only, it will easily break.
That thing seems like ESG box ticking bs
It’s a water based bonding agent with it. I imagine you could find the details if you search, being CE approved it should be there for all to see
Let’s not forget it’s a hopper gun too. Hardly a fine mist. There is a 6mm hole in the end of the gun!
Where is the orange boat gone…
Orange boat?! Ahh you mean Odd’s boat? Obviously that’s not ours but they sold up to build a new one. 👍
We’re like twin channels,
Sail hub and Odd life, both building a camper van and both building a boat!
sprayfoam fills the gaps in the paneling, this obviously did not. not convinced on the insulation of that van...
Yup, I can see why this comes to mind, it did me too. The thing is, it uses a different method. You can see that we taped up all of the holes in the structure and sprayed over it.
There is complete skin around the inside of the van, so we don’t need to fill the gaps.

Don't forget that this foam exudes toxic chemicals for a period of time after it hardens ot sure how long ?
Interesting, I never knew that👍🏼
Late comment because I’ve just watched the episode = so at least a tiny bit of logic obviously need glasses to see it or should it be sea it , whoops humour not required, sorry digress on steroids, looking at the cork spray thought about why it’s not used on concrete floors for insulation from the cold , thinking this because the having concrete floors myself definitely feel the cold coming from the especially in winter here in the UK, crazy thought maybe , take care guys = me .
Hey Kavan,
Thank ls for your comment fella, yeah we’re no dude why either. It could be due to the entrapment of moisture in the concrete as it’s porous. Mind you, it was originally developed for insulation of house walls so maybe you could try it?
Corksol would be your suppliers and installers to call in the UK 👍
If you do it let us k own how you get on mind!!
@@SailHub thanks for reply, if I do it I will definitely let you know , take care guys.
@@KavanOBrien cheers,
Likewise kavan!👍
Hi @KavanObrien, we have used Revecorck and Suberlev over floors and topped with SPC floor boards... so far so good in Northen Spain
@@cynthiamejia526 Never heard of those items, I will look into them , thank you for the information. Take care kind soul.
Bizarre strobing light flashes and loud rock music making hearing the narration difficult is a guaranteed way to alienate viewers.
As interested as I was in these forns of insulation, I don't want to be subjected to strobing light flashes and loud rock music drowning out narration.
I will obtain information from a credible source rather than this unfocused one.
You do that my friend. We really don’t need feedback from people in a rude manner anyhow. We prefer genuine people who want to help us grow in pleasurable way. Theres really no reason to be rude.
@@SailHub Your unfocussed presentation of strobing light flashes and loud rock music played over your narration undermines your channel credibily as it negatively affects the video.
This is objective criticism, not rudeness!
Perhaps consider the points I made rather than your easily hurt feelings.
I wasn't the only viewer to point out the strobing light flashes.
Thanks for your clarity here. We value supportive criticism for sure! And we’re always trying to improve on this. We hope you find some value in our other/future videos 👍🏼
The flashing at 2 minutes in is very distracting ... first video of yours I have seen, it will probably be the last.
Yeah, it’s a real shame. It wasn’t intentional either. Certainly wasn’t in our render, must be some upload issue. sorry about that.
Next time you're at a barbecue, toss a used cork onto the fire, and see what happens. (SPOILER, don't do this. It will explode.)
I rekon your going to find our next video on the cork insulation quite interesting!!
@@SailHub That was slightly tongue in cheek. I suspect that cork that's been shredded, then reconstituted probably won't explode. It's the air trapped inside raw natural cork that goes pop when heated.
Can’t imagine it from raw cork. Maybe alcohol impregnated variants.
The thing is, cork trees we’ve seen in bush fires are the only thing that survive and the cork is still harvestable.
Fiberglass and plastic is flame proof?
Plastic? No, that’s flamable. Fibreglass? Yeah, it’s what fire blankets are made from, it’s the resin you need to be wary of.
Great. Now tell me the EXACT chemical content of the glue!
Oh right. Of course I will 🤣 I mean, let’s face it, your so polite!!
Go find out yourself.
Just use aerogel insulation, everything else is a waste of time.
Bang in fella. If you’ve got the cash that is! It’s super expensive!!
