Cheap backer for Insulation
Hey guys. I'm in the process of finishing off a bonus room(500 sq.ft.) over my garage and master bedroom. I'm almost done the framing and had an insulation contractor here yesterday to give me an estimate. He said that
I need to consider my kneewall(5 ft. high) an outside wall and that it needs some sort of backer on ths back side, behind the insulation, to stop
any drafts. Makes sense to me, so, anyone have any ideas of a cheap material that I can nail to the back side of these studs?
