Rigid Foam · Scripps Ranch, CA

Rigid Foam in Scripps Ranch, CA.

Rigid Foam for Scripps Ranch 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.

Scripps Ranch: Scripps Ranch older master-plan attics are reaching the point where SDG&E rate pressure plus rising summer temperatures make the R-19-to-R-49 upgrade pay back in three to five years. Class A fire-rated assemblies and ember-resistant venting are now standard after the 2003 Cedar Fire.

Central San Diego rigid foam shows up under flat roofs and over slabs on older La Mesa and Lemon Grove homes.

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.
