Is chip-wood boards as effective for sound insulation as normal wood?
Probably. Maybe even better. What matters most is thickness and mass.

nobody here seems to have a fire problem with it. There are not fire regulations here and beside this the escape from the studio outside is easy.
Of course they are just using it as a bed and not as something hanging on a wall. Escape might be difficult if one the cotton treatments were ablaze, producing thick smoke and accelerating the fire up the walls to the ceiling. What the "Mattress" is encased in could contribute to it's combustibility as well.

You might also want to consider room dimensions when building your studio. Non square/rectangular rooms are best and dimensioning to minimize room modes is worth its weight in gold.

Re: Mattress Sponge as sound insulation and absorption?

Would compressed, nonwoven polyester fabric work? I can get my hands on plenty of resin bonded or needled for free. The needled stuff is soft and fluffy like poly batting, only denser, and the resin bonded stuff is more rigid like a scrubbing cloth, only more dense as well. I'm thinking of using some combination of the two, and I can go plenty thick.

Re: Mattress Sponge as sound insulation and absorption?

Anybody?

I went ahead and brought home a roll of the resin bonded polyester fabric today - I'm thinking I will probably do a combo of both that type and the needled, which is much softer. It seems this material should work ok.

Yes/No? Am I wasting my time with this material?

Re: Mattress Sponge as sound insulation and absorption?

Regarding the multi-pane window, the windows we got for our house are two layers maybe 1/2" or 3/4" between them, but each layer is a different thickness. The reasoning was the different thicknesses would result in different transmission modes, IIRC.
