Attic in Rancho Santa Fe, CA.
Attic for Rancho Santa Fe homes, done by a vetted local insulation crew. Most San Diego attics top out at R-19 or less. California Title 24 wants R-30 minimum on a re-roof and R-38 to R-60 on new and remodeled work.
Why is attic different in North County Inland San Diego?
Escondido, San Marcos, and Vista attics hit 130–150°F in summer and that heat soaks into ductwork running through them. Going from R-19 to R-49 plus air-sealing typically drops afternoon cooling load 15–25 percent.
