Closed-cell spray foam for Orange County commercial buildings, metal warehouses, truck fleets, and homes — with free on-site estimates county-wide.
Orange County's building stock leans heavily on tilt-up concrete and metal commercial buildings — the two construction types where closed-cell spray foam outperforms everything else. Foam bonds directly to concrete and metal, stops the condensation that coastal marine layer humidity drives on cool panel surfaces, and delivers R-6 to R-7 per inch where interior space is at a premium.
For coastal-adjacent buildings from Huntington Beach to San Clemente, the closed-cell structure matters: it will not absorb moisture, so salt air and marine layer humidity don't degrade its performance the way they do fiberglass.
Warehouse and distribution roofs and walls in Anaheim, Santa Ana, and Irvine business parks. Refrigerated and dry-freight truck bodies for OC fleets. Metal shop and hangar buildings. Residential attics and garage conversions where Title 24 energy compliance and limited framing depth make high R-per-inch foam the practical choice.
Every job starts with a free on-site estimate anywhere in Orange County, and most residential applications finish in a single day.
Yes — AAU Foam serves all of Orange County, from Fullerton and Anaheim down to San Clemente, alongside our Inland Empire and Los Angeles County service areas. On-site estimates are free.
Closed-cell foam runs $1.00–$2.00 per board foot; a typical 3-inch application is $3.00–$6.00 per square foot. Exact pricing depends on area, access, and prep — the free on-site estimate gives you a firm number.
Especially there. Closed-cell foam is a vapor barrier and cannot absorb moisture, so marine-layer humidity and salt air don't degrade it. It also stops condensation on metal buildings that coastal temperature swings cause.
