6 Replies

I am working on a 1950's colonial with attic insulation consisting of 2"x6" joists filled with loose fill fiberglass. The fiberglass is covered by 1" x 6" decking with 1/4" between the boards. I am…Continue

"Your last two statements, "The upfront cost of retrofits is a big barrier to comprehensive weatherization. Anything I can do to reduce the cost of installation will help," are compelling. You need a solution that makes sense, given the…"

"In order to do make a substantial difference in the air sealing of your home (this is possible!) you have got to be able to access the ceiling and do some caulking, foaming and rigid batting of air leaks.  While I feel for you and all the work…"

Enclosed Attic Insulation - Uncover or not?

I am working on a 1950's colonial with attic insulation consisting of 2"x6" joists filled with loose fill fiberglass. The fiberglass is covered by 1" x 6" decking with 1/4" between the boards. I am recommending adding cellulose to improve the air barrier and insulate. My question is whether I can get away with not removing the old boards, or maybe removing every third one? How much area is needed to ensure moisture can dry to the outside? It should not get damp because of proper ventilation.The…See More
