1" ductboard with foil back/should I remove?
I have quite a lot of 1" ductboard (compressed fiberglass), which seems to be similar in appearance to OC703.
I have cut these into 2X4 panels to be stacked 4"(or more) to make about 10 acoustic panels, and or bass traps. They all currently have the foil on the back.
I'm aware that, when using 703, leaving the foil on one side of a completed stack/panel will help to reflect some high frequencies back into the room.
My question is, can I leave the foil backing on ALL of my 2X4 panels when stacking. I only ask due to the pain in the A element of removing the foil. It also seems that removing the foil from all but one panel, would result in my losing some thickness in the process as well.
So, will leaving the foil back on all of my 2X4 panels result in less bass absorption, and/or too much reflective properties?
