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
"I consider my market anyone that spends more than $1500/yr on energy. I try to write different messages to get different segments to respond. I recently mailed 1000 flyers to home owners living in buildings with 2-4 units. I used "Can't…"
"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…"

"Thanks for asking this question - I've actually been wondering the same thing for personal use. I hadn't thought of the every-third-board idea (seems a good thought), but was instead pondering how far sideways I could shoot sprayfoam (the…"
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?
