Hello all, new member here, love the forums and the great articles all around! So now that I have found you, perhaps you can help in my search for soundrated drapes? Really have an urgent need hang serious sound dampening curtains in front of 3 sets of doubledoors (bedroom, roomates room, livingroom) in order to separate the home theater in livingroom from our bedrooms, and to keep my musicmaking in my bedroom out of the hometheater etc. Any advice on where to buy or fabricate heavy pro stage drapery for this application at a discount is also much appreciated... Was thinking we need serious weight, but Im rather uneducated about drapes. Obviously I wanted 21oz. velour all around, but I cant afford that. Theres a fellow who wants to sell me 16oz. commando cloth, but from my experience on stages I was thinking thats too thin. Am I just missing the mark here? For instance: does typical matte black commando cloth come double-sided and filled, and hence would be fine for sound dampening? If anyone has a link to some sort of sound rated per fabric type or ounce wieght chart sort of thing, that would be awesome. Thank you kindly and happy friday!
