I’ve watched dozens of videos on this exact topic, and always wondered why no one was trying to cover the rigid fibreglass without a frame. You get my subscription based on that alone, but then the fact that you went way over and above and were so thorough and so detailed and did such an excellent analysis that I’d get two subscriptions if I could! This was the first video of yours that I’ve seen. I will be watching more. Thank you so much!
Disagree. The corning 703 NRC is only good if unfaced, and you're left with dealing with naked fibreglass that you need to paint to make safe. Even in his own video, look at 12:45. There's a ton of loose fibres all over the weed barrier. That's a big red flag that could lead to lung and eye irritation in the future. I agree this is one way to create frameless panels, but other materials exist. Open cell foam is a much better material, in both performance and safety, but it's incredibly expensive compared to fibreglass. Another option is recycled cotton, which is already very stiff and has amazing NRC properties. You could sure it up with simple precut battons and glue if you don't want to use any tools. Again, I think he's made a good video and this is certainly a good option for a no-tool project, but I don't think it's the best as fibreglass is quite a hazardous material which is often glossed over.
This is the only DIY acoustic panels that I would actually consider making. Like idk why so many other UA-camrs are like "Hey you can do this yourself!" but then go to their professionally equipped workshop and wip out their table saws, staple guns, and work benches. Like bro I don't have any of that and never will.
Going with the 703, but have an idea to fix the imperfections or at least hide them...frame the panels with Cardboard. Salute to you Walt, I've done overly extensive research on and off for the last few years, never quite finding a perfect/cheap DIY solution...until watching this video. You answered every question I had before i got a chance to google it. Thank you Thank you Thank you
You make good points. I was impressed that you were not steered by opinion and bias towards mineral wool for sound absorbing panels (where fireproofing and soundproofing density it's not a strong factor), but use the NRC rating for sound absorbing quality. I liked your idea of keeping things simple, for a garage or working shop area, where bumps and rigidity for moving around isn't needed.
Really good video. I'm building a large garage, 30' x 40', with 10' walls. We used a scissor truss to give us a vaulted ceiling. The walls and ceiling are plastered. You would not believe the echo. I'm going to have to do something to address it. This looks like an excellent solution.
GREAT! Thanks so much. I finished my (rockwool) traps , now moving to panels. You just convinced me to skip the frames & go with rigid boards. Much easier.
A note for anyone making this in the future (Especially if you arent in USA) once you factor in price of Impaler clips, Cloud anchors, a few cans of Spray adhesive and the Fibreglass paint this isnt cheaper than going the wood panel route
Great content man. My 2cents from experience: the frameless coating works. Yes u gonna need more than suggested. Also 705 dont come in 4 in thick from most sellsers...i coulbe wrong but its hard to find. . Also u sprayed the whole panel with adhesive. 😂. Spay just the sides with adhesive.
Wow, thank you. This is exactly what I'm looking to do. My kids are starting up a garage band in our garage and I need some simple diy sound panels that I can make myself without tools, so this is awesome. You explained everything so well, thank you!
Regarding at time 9:30, NRC is the noise reduction coefficient. Reason conflicting data is that in ASTmC423 the RC rating is always rounded up to nearest 0.5, reason why it has NRC 1.05. Anything above 1 is 100% absorbing average, between 250 Hz to 2000 hertz. First NRC results, 250 Hz was at 0.71, whereby the 2nd NRC detail 250 Hz was at 0.78 which is why the first detail has a lower NRC at 0.95. This most likely from two different tests, showing that test retest reliability is off by about 10 but in reality the difference is negligible. Depending on the application, I look at the lower frequencies, with the thicker the absorptive material, the better it has at lower the frequencies. AS you had the panels on standoffs also increased their absorptive efficiency and NRC.
Cool video if you don't mind my suggestion but when your working with spray glue you must let it tack up prior to adhering it for future reference and for others let it sit for a few min and then put it on it will last much much longer appreciate your time making the video great ideer frameless
Agree with others this is the best video on this topic. Where can I find information on the impact of distance from wall or ceiling? I need to place panels on a ceiling to reduce standing waves, but space is limited.
Been thinking of DIY acoustic panels, and wondered why there couldn’t be a solution without a frame. Not that I couldn’t make one, but why would I mess with it if I don’t have to? Thank you!
Amazing. Absolutely awesome. Thanks to you, I just purchased two packs of 705 from acoustimac! I can't thank you enough. I have one question, what size print did you buy from Big Wall Decor? The fabric you got from them fit your panel perfectly.
Approximately how much does each panel weigh? Do you think they would stay up using a few of those 3M plastic velcro type tabs to avoid the need to put holes in the wall? Thanks! Great video!
Great video! The black fabric you put on the back, is that acoustically transparent too? One huge thing (you may have mentioned) is when you put these away from the wall/ceiling surface you can get twice the absorption as the sound passes through twice (provided that black fabric is breathable)
Hello Walt Could you test out how to Reduce the DB levels on a mitre Saw one Source besides the motor is the Blade which is like a Cymbal from a Drumkit which rings every time you lift the Blade after cutting your cut.
Hey Walt, thanks for an awesome video! I'm thinking of making some for my new place but I have one fear: Do the panels "leak" any glassfiber/stonewool through the fabric over time?
You mentioned puncturing with spikes for hanging. Are you puncturing all the way into the slab and is it sufficient to hold the panel from falling from the ceiling? Thanks
This is a really helpful video! I have textiles from all over. Is it possible to use hand woven cotton textiles, for example, something like bogolan mud cloth from Mali or Kente cloth from Ghana?
Thanks for the video. I want to make a frameless acoustic panel like yours but I'm thinking of sewing the fabric onto the fiberglass, rather than glueing it with adhesive spray. I know it will be a lot of work with the needle and the thread, but wouldn't it be better that way? Because glueing all sides of the fiberglass would make it stiffer and maybe reduce its absorbing quality... What do you think??
I don't think stiffness effects the acoustic properties. I say that because fiberglass boards and way stiffer than mineral wool but comparable in noise absorption. So not sure if the extra time is worth it for functionality, but if you prefer the look or method, its not a bad idea.
How is the smell? I have noisy apartment neighbors and want to make some for my bedroom. Does this method result in a panel with a strong "chemical" smell?
Please clarify a mistake made around the 12:12 time of the video comparing the edges of two different panels, when you call them both OC705. Did you mean to say the panel on the left is OC705 without edge coating and the panel on the right is OC703 with edge coating?
And thank you @Waltsreviews for the correction; I noticed there were a couple of other slip ups that you didn't correct too. Just a friendly suggestion to listen critically before final uploading. Cheers and thank you for the weekend project!
The cost of these has more than doubled since this great video was made. Amazon has the 703 at $125 for 12 one inch with free shipping. Considering gluing two together making it two inches thick. Any thoughts on this?
GREAT video! I will be building panels this weekend based on this video. Question - I would like 4" panels for better low frequency treatment. Can I sandwich two Owen's Corning 705 2'x4'x2" panels or would I be better off with Owens Corning 703 4" panels? I am unable to find 705 panels 4" wide, but I'm thinking the 705 panels being more dense would be better than a 4" 703 panel?
Opens with "save money while being lazy" I'm in. I'm building a frame type because and I've come to find out you can usually ask the lumber department in your local lows-type store if they have any scraps for sale on discount... Step zero: material acquisition XD
Sooo... how safe is this, though? Fibreglass is nasty stuff. I can see a ton of yellow fibres that are stuck to the outside of the weed barrier at 12:45. You don't want those loose fibres in your space. Also, since the boards are very stiff, doesn't this cause some high-frequency reflections and reduce it's performance as a good studio panel? Looking at the NRC, over 2k has a big drop in performance. I've seen people using recycled cotton (jeans) as a high-density filler that offers the same properties as fibreglass. It's more expensive, but it also comes in quite rigid boards. I imagine you could glue some thick card to the corners and achieve a similar build with no hazardous materials and no need to paint it.
Is it safe to install these panels in a bedroom? I noticed that you were wearing a mask when handling the fiberglass panels. Does the fabric do a good job at containing the fibers?
We didn't notice much fiberglass getting kicked up. Masks were largely worn because we were using spray adhesive. It's still probably a good idea to wear a mask when dealing with fiberglass panels, but you should be safe once they have fabric wrapped around them.
Do your health a favor and don't use unsealed fibre glass in your living room. You can also achieve great results with natural dampening materials like hamp or coconut.
Both the edge-coating and spray are actually quite detrimental to the acoustic qualities because they don't absorb sound, it reflects and bounces off. I don't recommend doing this, omggg. You defeated the insulation's own purpose 😂🤣 And, no air gap between the wall and the panel? There should be an air gap that's the same depth as the acoustic panel for maximum efficiency - you did it on the ceiling, but the gap is too large. Even though your room may sound better to you, it has probably lost 80% potential absorption
@@MrStupidHead Yes, of course, and I always shake my head at the amount of wood that people bring into the room for "soundproofing". If these people were to lay flat all of the wood that they bought, they will be able to see that it will take up a large amount of square footage - a wooden mirror, if you will. My idea is less than perfect, but what I do to combat the wooden mirror effect is put tiny spots of glue onto my frames and then place foam on top to at least help minimise any sound waves that could bounce off by absorbing some of them instead. I then wrap the fabric over the top to conceal the acoustic foam. I’m no rocket scientist, but I’m sure that I was able to create a far better room for myself than having any wood exposed. Any smooth surface will reflect sound, and so I recommend periodically assessing the room because new objects keep appearing because, let’s face it, we like buying toys 😂

This is better and cheaper ua-cam.com/video/pABvTWSxOes/v-deo.htmlsi=nJErYN4eOJlyCAam
Commenting for the algorithm cause this is by far the best video out there on sound panels.
Agreed. And I’ll be using the methods at the start of the video for ceiling panels cause it just makes sense.
Agreed, commenting for the same reason

Hands down, best video in this category! I will be using these materials and techniques in my upcoming project. THANK YOU
I really appreciate you putting this video together. Super helpful.

Agree with others this is the best video on this topic. Where can I find information on the impact of distance from wall or ceiling? I need to place panels on a ceiling to reduce standing waves, but space is limited.
Thanks . For sure the best and most cost effective method .
What measurements did you use for the fabric on those panels? I was confused when you were saying by the yard, is that the width?
Brilliant!. Could I used these as Bass Traps by mounting them in a corner at a diagonal leaving the air space behind? Thank you.
Was also thinking about this.. maskes sense. very good !
Been thinking of DIY acoustic panels, and wondered why there couldn’t be a solution without a frame. Not that I couldn’t make one, but why would I mess with it if I don’t have to? Thank you!
Holy hell where do they have awesome garages like this? Those on exist in multimillion dollar homes where I live.
The cheapest and best at absorbing sound are folded towls in a simple timber frame.
Amazing. Absolutely awesome. Thanks to you, I just purchased two packs of 705 from acoustimac! I can't thank you enough. I have one question, what size print did you buy from Big Wall Decor? The fabric you got from them fit your panel perfectly.
Same question. Was just on their site and it looks like the sizes don’t align exactly.
An excellent informative video. All the info anyone would need so subscribed & will using for my panels. 💯

The 703 / 705 edges are always damaged so this works if you're ok with janky edges that aren't clean
Great video but really tough to find this stuff in western Canada.
Can you send the link to solid gray fabric and for the black on the back you used to make it, please ?
Hello Walt Could you test out how to Reduce the DB levels on a mitre Saw one Source besides the motor is the Blade which is like a Cymbal from a Drumkit which rings every time you lift the Blade after cutting your cut.

Did you compare this to using a 3" EPS insulation board? Also rigid and fairly inexpensive...
No1 hidden factor is safety. Rockwool is fibrous & you defo don't want loose fibres floating in the air to breathe in.
Beyond Excellent 😊
That´s great. Let me as you something. It´s a good idea to put it in the ceiling to reduce echo? =)
Thinking of building a wall above a wall lots of notching maybe tape maybe paint after? foil backed might look ok Easier than fabric
Can you paraphrase? I think you doubled up some words.
Please clarify a mistake made around the 12:12 time of the video comparing the edges of two different panels, when you call them both OC705. Did you mean to say the panel on the left is OC705 without edge coating and the panel on the right is OC703 with edge coating?
Thanks for pointing that out. Yes the softer one was the 703 with edge coating on it, and the firmer one was the 705 without edge coating.
Thank you, was just going to ask for clarification on this!
And thank you @Waltsreviews for the correction; I noticed there were a couple of other slip ups that you didn't correct too. Just a friendly suggestion to listen critically before final uploading. Cheers and thank you for the weekend project!

The cost of these has more than doubled since this great video was made. Amazon has the 703 at $125 for 12 one inch with free shipping. Considering gluing two together making it two inches thick. Any thoughts on this?
It would work just as well as single 2” thick pieces. And if you’re thinking of using frames you wouldn’t need to bother gluing it.
Great tips!
I saw you had a OC 703 4" panel in there at 18:06. Is that also frameless? Can it be hung to the ceiling?
About how many spray cans of adhesive did you need?

Hey what did you end up going with and how'd it work out?
I posted what I did in another comment a few days later. I did build 4” panels. They seem to work well but I don’t have a way to validate with data.
Excellent vid full of useful info. The best I have come across. Thank You!
new sub here!
Does the glue decrease the acoustic performance at all?
That's a good question. I have a hunch that it does affect it.
Thanks for the video. Will it help insulate your house too?
a little bit, but not much IMO
Opens with "save money while being lazy"
I'm in.
I'm building a frame type because and I've come to find out you can usually ask the lumber department in your local lows-type store if they have any scraps for sale on discount...
Step zero: material acquisition XD
They stopped doin that I was just there
is the fiberglass board more rigid than the rockwool board?
How many cans of 77 for say...5 panels do ya think?
What's the Black backing on those Owens Corning panels?? Is that material allow sound through it
Weed barrier fabric
So no need for the edge coating on the 705?

is this same with rockwool ?
I like this video
🔥🔥🔥
Its been my experience that you are going to have to use at least2 coats of M77
Couldn't you just mix black dye with alcohol and spray it! The glue for wrapping it will block the absorption to some degree
Is this Viggo Mortensen's son or brother ? 😀
Do your health a favor and don't use unsealed fibre glass in your living room. You can also achieve great results with natural dampening materials like hamp or coconut.
No way rockwool or fibreglass are the top choice..the cheapest and have highest nrr is the humble EPE or polyester fiber
That room has a lot of echo LoL
Ikea finnsby + rockwool sonorock eco + fabric = bargain broadband absorber

This stuff is prohibitively expensive.
