My “stick-built” home has an R-19 rating. What makes a SIP home so much better?
“Standard” fiberglass insulation has the ability to settle, allow air infiltration and can actually allow for air circulation within the wall, thus reducing the actual “R” factor of the wall, usually to an actual 9 to 12 “R”-factor, NOT R-19. The SIP’s we use in BAI Homes offer an “R” factor of 22. There is no settling and no air infiltration, so this is a “real” and fixed “R” factor. Plus there are fewer studs to conduct cold into your home, this is refered to as a “thermal short”.
