Attic in Granite Hills, CA.

Why is attic different in East County San Diego?
El Cajon, Santee, and Lakeside attics are the highest-return zone in the county for insulation. Summer temps hit 150–160°F and most original tract-home insulation has settled to R-15 or worse. R-49 blown-in plus air-sealing is the standard scope.
