use a staple gun (small holes in the wall tho) or u can pick up sum insulation board from home depot or wherever and staple, glue, tape etc, the panda film to the insulation board and stick it in the room. downside is u lose about an inch of each wall. (the insulation board can be cut to ur room size) this mite help with ur climate control as well. u dont need to go any higher then the lights with the panda film either. the other suggestions above are good as well. this was just another option but prob more costly then anything. hope shit works out! -boom
