How to insulate the ceiling/roof?
I have a chalet-style house in Virginia which needs insulation. Built about 1970 as a Linden model, it is hard to heat in the winter. We installed a propane fireplace to help the heat pumps in the two stories plus basement. Summers are not such a problem because the surrounding trees give shade.
These houses have no attic. The second story ceiling is about 10' on a good slope. Exterior walls are tongue in groove and interior walls are cedar. I am replacing all the windows, but the roof is the worst problem. The frame on these types is tied to the roof, so it can not just be changed at will. It can only support modest additional weight.
i had thought of spraying solid core foam 4" over the existing ceiling. This would add R24 to whatever is there now, maybe R19. That would damage the look but help with the heat loss, I hope.
Does anyone have any experience with such a situation?
