Question
i have a room above my garage that i am finishing. i want to vault my ceiling. the rafters are 2x6. do i have enough room for the proper insulation?
Hi Shane, it really depends on where you live and the type of insulation you use. A 2x6 cavity filled with fiberglass batts will only provide you with an r rating of 19. Most zones in the US recommend at least R-39 or higher for roof insulation. However there are some insulation companies providing spray foam closed cell insulation which would give you a high enough r value within your rafter space. I hope this info helps feel free to write again regarding this or other matters sincerely Bruce Johnson..bejohnsonconsulting.com
