What's the best way to insulate cathedral ceiling? Where I live (central NJ) attic R49 insulation is recomended. I don't see how to achive this with fiberglass insulation even if using 2 X 12 ceiling joists. Of cause it is possible to use rigid foam insulation but it seems to be expensive and also will create thermal bridging where joists are. I wonder what's the best and optimal way of insulating cathendral ceiling to required level>
