Rigid Foam · Del Mar, CA

Rigid Foam in Del Mar, CA.

Rigid Foam for Del Mar homes, done by a vetted local insulation crew. Rigid foam handles thermal bridging, the heat that bleeds through studs and rafters. The crews we send install EPS, XPS, or polyiso continuous insulation on exterior walls, under flat or low-slope roofs, on the underside of slabs, and as a thermal break under siding.

Del Mar: Cost depends on access, square footage and scope, and the pro quotes after seeing the home. Marine humidity plus salt spray make air-sealing more important than raw R-value, and discretion plus daytime quiet-hour scheduling are non-negotiable.

EPS, XPS, or polyiso, which board?

EPS is cheapest and vapor-permeable; good for exterior walls and below grade. XPS has higher R per inch and resists moisture; common on roofs and under slabs. Polyiso has the highest R per inch but loses some R in cold weather, fine in San Diego where it rarely gets that cold. The pro picks based on assembly and budget.

Will adding rigid foam mess up my windows and doors?

It pushes the wall plane out. The pro extends window and door jambs with proper trim, flash to drainage planes, and detail water management. This is normal exterior-insulation work and the pro plans for it on the quote.
