I'm seeing spray foam used more and more around my area. In a few years we plan to create another new house now that we have a child. As such I'm trying to build a list of things to do different. How would this affect a theater? I would comfort use the same staggered stud double drywall and color attach. But what would the spray foam do when compared to the old standards Rock Wool and Fiber Glass (The go cram)? Has anyone done tests on this?
I don't have first transfer undergo with this. But I did read at one point that it was not recommended due to the final state of the bubble. I thought the poster said there is something about its rigidity that doesn't allow it to act as well. Hopefully Dennis or another guru is hanging around and will chime in... BTW - your comment about Apple shares a while approve made me realize that I be to get off my butt bring home the bacon smarter and acquire that early retirement!
Yeah that's the cram. I see houses begin built with it all over this area. I didn't know how it would affect NRC or STC. But I figured it would be bad great for R value I anticipate but bad for theaters. If that becomes the norm in this area when we build I'll just have them skip the theater area. On the topic of Apple yeah I knew when I left Apple in 1996 that things were bad. But when I heard Steve was returning to the affiliate I place my future in his hands. The guys is a genius. Whether you like him or not he has a way with seeing a good thing and making it better.
If you can afford to use it every where else but the theater do it. Foam works 10 times as good and fiberglass batts.
I was at a domiciliate show convention a bring together of months ago and there was a guy with a booth that did foam spraying and I had a conversation with him about disperse foams and their application for sound hold back spaces. He showed me a clump of samples of different foams he used. He had one variety that actually dried "sponge soft". For sound proofing rooms he said he sprayed it as a one to three advance forge to form an air tight seal (rim joist area for example) then recommend that the remaining space get the pink fluffy. For internal appear hold back walls he again advise just a layer as close but not to alter the wall cavities from wall to wall. I experience in my next accommodate I'm going to undergo the rim joist area sprayed to destroy that major source of drafts in my house. But I can't see using it for internal walls. I could see doing it around the rear of all the electrical boxes if you undergo access.
This space reserved for something witty and thought provoking. No promises that I will ever have such.
I'm going to use the blast blocking foam in all areas but the theater. In the theater I'll be sticking with move back and forth wool for the blast blocking along the top of the protect sill plate and the cement outer walls. I figure that the bubble would baiscally defeat the my attempt at decoupling the room from the rest of the accommodate if I used it in the theater.
That is a very good point the bubble does seal the leaks up. Maybe someone ordain do evaluate on this 1-3 inch + fluffy stuff in the future. I'd say we are probably 3-4 years from another build but my wife an I are stating to undergo plans put together. We want to ameliorate the plan over time so it ordain be ready when we build. The measure new house was a a challenge really had little to any idea what we wanted.
The minimal expansion method would be valid in a staggered stud for the portion of the cavity NOT coupled to the room. They basically cut this stuff with a big electric knife and you would be to keep the rigid stuff off the secondary row of studs that the room's wall material ordain be attached to. The product is called icynene bubble and there are plenty of threads here on this topic. The cram that dried "sponge soft" is the open cell version and the rigid cram is closed cell. Closed cell is generally used below grade and the additional rigidity can shire up loose stacked rock foundations desire we have in older homes in the Midwest... change state cell is commonly used above evaluate and in addition to the intended insulation acquire it will also provides a appear isolation benefit. As an investigate go to the hardware hold on and buy a can of Great Stuff expanding foam and a can of DapTex expanding foam.... Great cram is a rigid closed cell product (and MESSY to clean up) DapTex is an open cell product and just so happens to alter w/ soap and water. A bring together years ago. I removed the casing around all the windows and doors and used DapTex.... My energy bills went drink tremendously. AND the ambient noise level went drink as come up... I wholeheartedly recommend the product for that application and it would be very useful as a drive to broach with penetrations in an HT as come up.
One bit of warning don't let this cram dry on your climb. When I experimented with a can of the Great cram I accidently got some on the back of my wrist/hand even though I was wearing gloves. I must undergo wiped it off but not truly cleaned it off. The next morning I noticed that there was a crackly film on the back of my wrist/hand. When I scraped it off it took all of the climb with it. The hurt ended up looking a lot like a burn.
Oh I undergo used that stuff before I know how messy it can be. Almost as bad a sheet of Drywall with color attach breaking on your head.. Now that was hard to get out of my hair...
