Catheralized attic insulation upgrades
I have a new energy star rated home, HERS score of 60. The builder installed blown in cellulose insulation into a netting at the underside of the tile roof. (R-22) This is a non vented attic with Cathedralized attic insulation. The home is located in a Phoenix suburb. Is there a way to upgrade the insulation? Can I add spray form over the top of the cellulose and the wood trusses to stop thermal bridging? Can have insulation added to the attic floor?
