Rigid Foam in Carlsbad, CA.
Rigid Foam for Carlsbad 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.
Why is rigid foam different in North Coastal San Diego?
North Coastal rigid foam goes on siding redos in Carlsbad and Encinitas, adding 1–2 inches of polyiso under new siding gives a continuous-insulation upgrade that pays back on cooling.

How does Carlsbad's climate affect this service?
Carlsbad spans coastal Village to inland La Costa and Bressi Ranch master-plan. Older Village beach bungalows have settled underperforming insulation, La Costa and Aviara HOA tracts mostly need ductwork and air-sealing work, and the affluent demographic supports premium spray foam and energy-modeling-driven scope on remodels..

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.
