This soundproof enclosure is amazing. Excellent project, so you can have a CNC at home without your wife expelling you to the street. This sound isolation is absolutely excellent. It has completely blown me away. I have subscribed to your channel because I have a lot to learn from you. I hope you will publish the construction step by step, since I will be very vigilant to try to achieve something similar. Thank you very much for sharing with us
Thanks! I also hope to find time to make video edit about step by step instructions but I got so much to do those past few months as I'm starting my own business :)
Thanks! I used some simple eccentric latch to close&tighten the door. They look like those: www.fruugo.se/4-pieces-right-angle-adjustable-buckle-vertical-quick-clamp-box-buckle-latch-clamp-right-angle-buck/p-190084075-405949283 I got those from Bauhaus, I'm sure you can find in any local similar shop.
Great results Damian. Kudos. Quick question. You've said you set up the layers as follows from the outside in (correct me if I'm wrong): OSB (what thickness) > Green Glue > drywall (what thickness) > Rockwool (I'm assuming 3" batts? > MLV (what thickness) > closed cell foam (what thickness). Did you build from the outside in, or vice versa? Thanks, and great job!
Thanks, here are few more details: OSB (15mm) > Green Glue > drywall (12mm) > Rockwool (45mm) > MLV (4mm / 7-8kg/m2) > closed cell foam (4mm) I first built separately the side panels OSB-green-drywall (size adjusted with max. 0.5mm accurancy - an important detail I believe). Then I put those panels together with screws in the OSB edge to form a 5 sided box (I built the door - the 6th side - at the very end). When putting the 5 sides together, I took particular care of not leaving any air gap between each OSB/drywall panels: on the edge of each panel I have added a fin foam tape of 1.5mm ( www.affixit.co.uk/single-sided-foam-tape.html ) which got squeezed when tightening screw and filled any potential tiny air gap (if air can pass - sound can too) => I believe those details play an important role in the soundproofing efficiency. Just with OSB&drywall, each panel is about 20-25kg so nearly 100kg once the 5panels are put together => this is to take in consideration for practical handling of the parts. Then after I had an empty OSB/Green Glue/drywall box, I have built inside a simple wood structure to hold the Rockwool & MLV (without putting any screw in the OSB/drywall part - this to prevent screw to transmit sound vibration - I even put some foam tape ( www.affixit.co.uk/green-glue-tape-50mm-x-30m.html ) between wood structure and the inside panel of the box to dampen vibration). For the MLV/CCF part, I found a roll from www.carinsulation.co.uk where the MLV&CCF where already glued together, they don't have this particular article available anymore but you can still see it from the google cache: webcache.googleusercontent.com/search?q=cache:O0QHLYJWtkAJ:www.carinsulation.co.uk/product/peacemat-xxxx-6kg-vehicle-floor-sound-deadening-noise-barrier => on the description it said 3mm MLV & 3mm CCF and 6kg/m2 but when I received it and measured it, it was 4mm MLV & 4mm CCF and ~8kg/m2 - I did not complain :)
Hello Damien, Awesome job on this. I've read through the comments and got the construction details, one item missing is the viewing window you've added. I'm guessing that it is plexiglass and that you've added the foam tape between the plexiglass and the wooden outer layer, but please advise what you've done here and what the thickness of the plexiglass is that you've used. Thanks and looking forward to your feedback.
Thanks! For the window, I have put 4 plexiglass window of 5mm each on top of each other. And yes, each plexiglass window is encircled by foam tape (no direct contact between plexiglass&wood - to dampen vibration transmission). There is about 3mm of air gap between each plexiglass windows - I have used some regular door seal tape to hold the spacing between plexiglass windows - the idea is just to avoid wood or hard material between parts to make it harder for vibration&sound to propagate.
Hi Damien, I need to build a sound proofing enclosure for my compressor and would love to know more about the materials you used and how you built the layers.
Great example of an efficient box, but an even better example of how important it is have the door air tight. That was very impressive, well done! What is that window made of? I am planning to build a box for my PCs, but I want windows to show them off still.
Thanks! The window is a "sandwich" of 4 Plexiglas of 5mm each separated by adesive foam tape* to dampen vibrations between plexiglas layers. To prevent sounds vibration to propagate too easily, there is NO rigid structure (wood/screw) directly in contact with plexiglas even on the side, there is always foam tape/material between rigid parts of the structure and plegsiglas. * I used regular door noise seal isolation foam tape you can find in any house/build materials shop (got mine from Bauhaus).
@@damiendd09 Thank you for the reply. I am only trying to isolate noise from PCs, so I might try using just two pieces, but I was wondering whether to screw holes through them or not, but seeing as you haven't , I don't think I'll do it either, no need to over complicate things, or risk breaking the plexiglass.
I used OSB, drywall with green glue on the outside and rockwool with MLV (Mass Loaded Vinyl)+CCF (Close Cell foam) on the inside. There are also quite few details I paid attention while making this build. I will do some video but I cannot promise when, will try to do it as soon as I can!
@@damiendd09 I build one like yours for myself. But im having a litle problems with in temperatures. How are you dealing with that. Thank you soo much and good job til now.
@@damiendd09 Do you mean: OSB Green Glue Drywall Rockwool Sonorock MLV CCF? Unfortunately, here in Germany "Green Glue" is really expensive to import (~120€ for 2 bottles and the gun). I guess the trick is to have something elastic that doesn't dry out between the two shells, without screwing through them. Maybe I can find an alternative acoustic glue somewhere.. what did you use to seal the door?
@@SuperJecd sorry for late reply, I somehow missed your comment.. yes temperature can be an issue if too much heat is generated inside the box and you leave it close for extended period of time. If it ever become an issue for me, I thought about adding some water cooling system with an heatsink right behind the airoutlet of the vaccum cleaner. However at the moment it has never been an issue as rarely leave the box closed with spindle on for more than 30minutes.
@@drRazor1111 sorry for late reply, I somehow missed your comment.. I think I saw some alternative to green glue but not as efficient from measurements&tests of my research I did back then. I bought the Green Glue for fairly good price from this UK webshop: www.affixit.co.uk/green-glue-noiseproofing-compound.html It was not possible to ship outside UK by placing the order directly from their web interface but I sent an email to ask them about delivery in EU (Sweden) mentioning the list items I wanted, I did wire transfer as per their instructions and received everything few days later.
Windows is made with 4layers of 5mm plexiglass in sandwich with foam on the edges between each layers. This to prevent transmission vibration/sound from one plexiglass layer to the next one😉
Yes after 1h non stop, it gets warm inside but it has not been a big issue for my use so far as the temperature drop quite fast as soon as I open the door.
oh yes, it definitely heat up inside when I run my CNC router for 20min with door closed especially when the vacuum cleaner/dust collector is running! I just open the door for less than 1minute and most the hot air is gone!
I haven't kept a very good track of all expenses for the enclosure build but I think something between 500€ and 1000€ + a lot of time!! Most expensive was the MLV (Mass Loaded Vinyl), Green Glue, foam tape, plegsiglass.
