What is the best option for insulating a vaulted ceiling?
Hey guys this is my first question ever on any forum so let me know if i need to supply mor info or not and i’ll apologize in advance if i sound stupid because i’m far from carpenter. I live in northern saskatchewan and am building a new 1500 square foot home. I have had it in my mind from the begining of the build i wanted to use spray foam to insulate the house because i am heating the house with an electric forced air furnace and want it pretty tight. The problem is there is a vaulted ceiling in part of the house and I’m not sure what is the best way to insulate that part of the house and i’m a little confused on my spray foam options besides spraying six inches of foam to get close to my r40 value i need. I also kinda wanted to know if i’m wasting money if spray foaming the walls and using convention fibreglass in the attic space.
