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. We 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.
Why is rigid foam different in Coastal San Diego?
Coastal rigid foam is most common on flat-roof and low-slope reroofs in Coronado and Del Mar, closed-cell board over the deck handles thermal bridging and adds water-tight margin against marine moisture.

How does Del Mar's climate affect this service?
Del Mar is custom beach-estate territory with home values typically over $3M , full-envelope spray foam, energy modeling, and integrated HVAC right-sizing are the working defaults on most projects. 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. We pick based on assembly and budget.
Will adding rigid foam mess up my windows and doors?
It pushes the wall plane out. We extend window and door jambs with proper trim, flash to drainage planes, and detail water management. This is normal exterior-insulation work and we plan for it on the quote.
