Rigid Foam in Chula Vista, CA.
Rigid Foam for Chula Vista 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 South County San Diego?
South County rigid foam is mostly new-construction and ADU work, continuous insulation on exterior walls and slab edges in EastLake and Otay Ranch builds.

How does Chula Vista's climate affect this service?
Chula Vista is San Diego County's second-largest city, split sharply between older west-side stock (55-plus years old, original underperforming insulation) and newer east-side master-plan developments (Otay Ranch, EastLake, Rancho del Rey from 1995-2015). Different scope on each side , full upgrade west, ductwork and air-sealing tightening east.. South County rigid foam is mostly new-construction and ADU work, continuous insulation on exterior walls and slab edges in EastLake and Otay Ranch builds..
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.
