Insulating a Cape roof

trguitar | Posted in Energy Efficiency and Durability on

Hi All,

I’ve been upgrading the insulation in the house, and have noticed that the roof insulation in my cape is only R-19. I believe code here in Massachusetts is R-38. The rafters are 2×8. There are soffits, but no air channels up the roof — just R-19 batts shoved in there.

What are my options for getting to R-38? Not fiberglass, I’m pretty sure!

I’m looking for education on all my options before deciding what to do.

Thanks!

Alex
