Inquiry (采购产品): 4' Acoustical Foam I have a home studio and I have 3 windows approximately 3' x 7'. I need a foam insert that I can insert in to the windows when I am recording and mixing, then take out whent I'm not using the room as a studio. I am guessing a 4" thick panel of acuositical foam would work. Your thoughts and suggestions would be appreciated, along with an approximate price for the panels. Thanks.
