gtblum Posted January 4, 2010 Report Share Posted January 4, 2010 How long does fiberglass insulation last before it is no longer doing it's job? The right side of my house has a vaulted ceiling with new insulation and rock. The left side still has an upper bedroom with the original fiberglass and rock. Looks to me like gravity wins again. Thought I'd get away with a fresh paint job in that room. Who says you can't learn much about a house with a snow covered roof?
