hey ! the thinkness of 12inches and R-Value 3.5 hope this helps.

happy you enjoyed it! we are manufacturing CLT and also doign a high performance framed wall. Agreed on needing a local woodfiber insulation. We actually order ours from Germany but there is a new factory in Maine @timberhp who we are hoping to be able to get our product from!

@@fab_structures Thank you. Do you find CLT an overkill for most applications (except as a replacement for concrete slabs?)

Yup you are right! We generally apply a clear or whitewash finish on the wood depending on client's preference.

@@fab_structures Can you fur out the CLT Wall with 2x4 & put drywall + paint? All the houses built with CLT that I’ve seen on the internet all have one thing in common, exposed CLT. Nothing is drywalled & painted. Can it cause issues because I know Wood is hygroscopic so the CLT Wall would absorb moisture & in my mind that might trap moisture between the CLT & Drywall? Exposed wood is beautiful but for me it would feel like you’re living in a wood box or crate.

@wd8005 you can totally cover it up with Drywall. We just completed a project which we will hopefully be able to shoot soon using industrial CLT so not a finished CLT since we covered it up. insulated it with woodfiber board and high performance SIGA majvest as a membrane.

@@fab_structuresThis is what I'd like to consider for our next build: CLT walls on T-Studs (or steel), wrapped in a vapor membrane, insulated behind the interior CLT wall with Rockwool or Hempcrete, and plastered on the inside (over the CLT) with hydraulic lime or Termorasante (new Italian aerogel + lime plastering, super insulating). Does that sound possible?

Sorry it took so long to respond to this! better late than never :) partly because of the interior layout, (both gable walls are bedrooms so the idea was to keep those walls solid for the beds... and also partly because there isn't much happening on the outside.. One gable faces the garage/driveway. Instead, the bedrooms have the big southern windows to get that solar gain.

@@fab_structures No worries! UA-cam comments can be hard to keep up with. Appreciate the reply.

Hey! good question. Research shows the benefits coming from wood fiber board as a fire retardent which we believe is higher than for rockwool check out some of this reasearch bioresources.cnr.ncsu.edu/resources/combustibility-and-characteristics-of-wood-fiber-insulation-boards-prepared-with-four-different-adhesives/ Also Timber HP has a lot of info on WFB fire this check them out here: ua-cam.com/video/14u5MnKj_p8/v-deo.html

It’s in Wakefield, Quebec

Ok

What’s the cost compared to a traditional timber frame garage

@@rickybarratt535 Pretty much out of sight, due to a lack of builders being comfortable with the material. Turns out that there's a big price adder if you ask a builder to do things they are not comfortable with.

@@rodshop5897 yeah but what about just timber vs clt material cost comparisin

Great catch! Since we made that video it’s actually been proven not to be 1 tonne and much less. Here is some data that might help explain the actual process of what’s occurring and it’s calculations! www.woodworks.org/resources/calculating-the-carbon-stored-in-wood-products/

@@fab_structures thanks, these calculations are much more convincing 🙂 so I can see 0.6 tonne of wood can store about 0.26 tonne of carbon, that actually relates to one tonne of CO2 equivalent. Thanks!

Hey! thanks for the feedback. we are working on new content ! As you know these types of homes take almost a year to build so getting the footage also takes the same amount of time. And a few new ones will be coming out this year :)

thank you!

@@fab_structures Size ?

@@lawsonspedding6136 1500sqft

@@fab_structures Just the size I’m hoping to build 👏👏👏👏Any plans available ?

@@lawsonspedding6136 get in touch info@mchqc.ca and our sales team will connect with you!

Thank you! The panel was rabbeted to leave a gap and then painted black.

Industrial grade CLT is not as nice a finish as an architectural grade CLT. It is hence, less expensive and makes more sense if it's going to be covered up with drywall in the end.

Yup you're right there is an engineering pattern of screws through the Wood Fiber Board insulation into the CLT !

@@fab_structures Amazing wall! do you worry about thermal bridging through those rain screen screws into the CLT?

@@everettk333 Thank you! In our experience no matter what you do there there will always be a weak point in the wall system and if an 8 mm screw is the weakest point we’re pretty happy with that :)

your looking at maybe a 15%-20% difference.... a lot of their budget went into interior finishing which regardless of passive or not would've stayed the same.

@MCH Group I suppose the mentality of going a bit smaller would potentially offset some of that difference. Think better, not bigger!

Thank you! good question and no it doesn't seem to be an issue for our clients. The insulation in the ceiling is huge which might have a positive impact there for sound absorption.

No we really don’t have any issues with the acoustic or echo.

@@yousis758 Thank you for confirming this! :)

M-Sora! We supply a lot of our windows from them for our projects. Very affordable as well compared to others.

Great question and yes it is a little hard to see. There is actually capillary break between the two materials ! Hope this confirms your questioning.

mainly more expensive

@@fab_structures makes sense. any thoughts on putting the WRB membrane onto the exterior of the wood fiberboard vs onto the exterior of the CLT assuming the wood fiber board is treated and rated to serve as a WRB?

@@tubulartuber you are not wrong and yes you could do it onto CLT. We mostly do residential and our inspectors need to see WRB to satisfy code which is why we do it that way.

We use a specific polyurethane glue that glues the Styrofoam together. Hope that makes sense.

hey! thank you! best thing would be to send us your project through our online client form (contact us page) so we can give you a rough idea.

Thanks! We'll be doing a video just on those specifics but for now yes majority would be through interior walls. However, when needed on the outside walls, the electrical chase-ways are CNCed in the manufacturing stage.

Yea that’s one way to look at it. Other advantages are sound, fire, it being an interior finish, more carbon sequestration in building, sismique strength. But the technology is more used in the commercial field to compete against concrete and steel. Thanks for your question !

Frame houses are considered "paper houses" by many ppl and can't compete with brick (ceramic block, Ytong, etc) so the, point in clt is that u have real solid hard walls! I'd never built a frame house or sip panel house. Clt I would consider.

it's 2.64 per inch of WFB

Dang that’s not good at all rockwool is 4.2 per inch

Love the backward cap Principle

Thank you!
