Is it practical to create an airtight barrier within a scissor truss?
First off, I would like to again thank you Martin and others helping me take my large home from using literally thousands of gallons of oil to last season using 8 tons of pellets. The advise was hard to take but true, people maybe questin but follow. I am building our retirement home in zone 2 in hurricane prone area and want to build a ventless roof to avoid windblown rain entering soffits and ridge. I would like to a 2 inch layer of closed with rockwool but can i create a good enough barrier within the truss or just use all foam, expensive of course thanks again
