i need to sound proof the house i am building?

Question

i need to know where to find large sheets of 1/4 inch thick Styrofoam, yes i am taking the cheap out

Answer 1

You would be better off to buy the new sound-proofing gyproc on the market it is like putting up 10 sheets of gyproc on the wall and really sound-proofs a house.

Answer 2

First- you will get minimal benefit from that approach; I wouldn't consider it worth the effort or cost. If you insist on it, you could use the 1/4" fan-fold foam insulation trypically placed under vinyl siding. It comes in bundles 3' x 50', so it goes us fast. It's more durable than beadboard styrene, and most all lumberyards have it.

Since you are building, you are probably planning to insulate. For the same money it will cost you to add the 1/4" foam, you could upgrade your insulation. Instead of using basic fiberglass batts, use sprayed in bonded cellulose. This is very efficient as insulation because it fills every nook and stops convective circulation, but it also has wonderful sound control characteristics. You get both utility savings and great accoustics.

I build large custom houses, and customers are shocked at how well the homes shut out noise.

Answer 3

ok, first of all, a quarter inch won't do much.

second of all, real styrofoam does not come that thin
reall styrofoam is blue, not white, is denser and has a layer of plastic on it.

a quarter inch of the cheap white foam won't do enough to be worth the bother. do it right, or do not bother. Dead Air is what blocks heat, cold and sound. normal fiberglass insulation will do better than the foam. the surface covering it has a lot to do with it too.

if you want to use foam, use real foam, not the white stuff, but soft foam the least density you can find, and seal it up insid the walls some how. jeesh...ameteurs...study up before you try such things.

Answer 4

What is going on top of the styro that u want to install?
Use 7/16 OSB sheathing on with tyvek wrap and Hardie siding and u get just as much insulation and a quality exterior look.
Use R13 for 2x4 wall and R19 if u are using 2x6 walls

Answer 5

ive been putting the HVAC system in a movie house thats going in locally, and i was amazed to learn that they are using 9 layers of 5/8 sheet rock on the walls to sound proof them. they have two parallel walls that are insulated, and one side gets 5 layers, the other side gets 4. if that is good enough for in between two theaters in a movie house, im sure a double layer on the walls of a house would do a great job there.

Answer 6

Your best bet that will make the most sense is to insulate the interior walls as well as the exterior walls. Also install double pane glass windows and solid core doors. I think your foam idea is great but you'll probably find that it would be messier and more time-consuming than batts of faced fiberglass.

Answer 7

Well, are you soundproofing to reduce inside noise or outside noise. Aside from the styrofoam and insulation suggestions, if your carpet your walls inside, it will absorb alot of sound and prevent that echo you get from a large empty room...just my unprofessional suggestion.

Answer 8

It is probably cheaper to double skin the drywall,
I think it is cheaper and more effective than foam.
It is all about interposing mass, plus transiting sheet to sheet.

It will kill the high frequency better and soak up more low frequencies.

Answer 9

The Gyproc company have a product called Gyprock® Soundchek™ it seems to have the properties your looking for.
