well i've been a member of this forum for quite a while and have never posted because I quite frankly have had nothing intelligent to contribute. To continue with that theme I have decided to ask a dumb question. I am moving my mother in law out of her old house (dry rot, termites, black mold) and into her detached concrete block garage. I have studded the walls with 2 x 6's, intending to take the almost new 6" fiberglass insulation out of her old attic (2 layers) and insulating the walls of her new garage/home with it. Now; after the walls are studded I have discovered that the insulation in the old attic is actually 8".
Question: If I go ahead and stuff the 8" fiberglass into the 6" walls I know i will not get the full R value of 8" but will it be less than the R19 i would get if I bought 6"?
