Rigid Foam in Tecate, CA.
Rigid Foam for Tecate 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 Backcountry San Diego?
Backcountry rigid foam handles freeze-thaw exposure and adds thermal mass. We use it on under-slab and slab-edge applications in Julian and Pine Valley cabin construction.

How does Tecate's climate affect this service?
Tecate is small US-side rural border community , very limited population (~100 US-side), inland heat with fire risk, and scattered residential parcels. Most insulation work is full-scope rural property coverage with ember-resistant ventilation mandatory.. Backcountry rigid foam handles freeze-thaw exposure and adds thermal mass.
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.
