From San Diego to Sacramento, Prestige Insulation supplies ASTM-compliant fiberglass batts and mineral wool direct to California contractors. We navigate Title 24 requirements — and we stock what you need.
California spans Climate Zones 1–16 under Title 24. Requirements vary significantly by county — from R-13 walls in Zone 1 coastal areas to R-21 and above in inland and mountain zones. We can match your project's exact spec.
Kraft-faced and unfaced batts in standard and high-density grades. Available in R-11 through R-49 across all widths. ASTM C665-compliant.
AFB and SAFB mineral wool for walls, floors, and sound-party assemblies. Non-combustible, moisture-resistant, and dimensionally stable.
