i love negative rep
i built a frame the exact same size as the (in my case) rock wool
1: put material on floor
2: put rock wool on material
3: put frame on back of rock wool
4: pull material tight, staple to frame
then you have a trap with exposed sides, and an airspace behind it that's the thickness of the frame you made.
