We live in a split-level home built in 1964. It has cathedral ceilings in the LR/dining area. The roof is gently sloped and it appears there is only about a foot or so space between the ceiling(s) and the roof. Is it possible to insulate this space. I have had a couple of contractor in and they suggested it would be more trouble than it's worth..that is the R-value wouldn't be increased enough to cover the cost of the work even over 10 years.
We have already replaced all windows/doors. Our heating/cooling costs are reasonable (we're in Quebec, the power generating capitol of Canada :) ) so I am now wondering whether it's even worth the trouble.
