What is the best way to insulate our new home?
After reading several of the articles on insulation of walls and vaulted ceilings lately, I am a bit confused. We live in SW Montana. Part of the home includes a vaulted ceiling in the great room, the rest of the ceilings are standard 8′ heights. The plan calls for 2×8 rafters in the great room. My plan was to 6″ bats in the ceiling, then cover with closed cell rigid board (up to 2 “) then gyp rock to achieve a decent R value. Likewise, the walls are 2×6 so planned on batts with closed cell on outside and then installing cedar board/batten.
Any suggestions on what is best (foil wrapped iso board ….) Spray foam for us is out of the question due to the cost. Our primary heat is an outdoor wood boiler with underfloor radiant heat and baseboard in upper floor including a wood stove in great room.
