Complete spray foam insulation for St. George's real desert summers

We're not a general insulation company that also happens to offer spray foam — spray foam is the only thing we install, which is why we do it better than anyone else in Washington County. But we don't narrow the scope to match: residential and commercial, new construction and correction of prior spray foam work, all under one crew. Whether it's a 130°F+ attic pushing your AC into overdrive, an uninsulated crawl space, a metal-building shell, or a new build to St. George's Zone 3B code, every project starts with a free, no-pressure assessment.

Attic & Roof Deck

Roof-deck and attic-floor spray foam that shuts down the single hottest surface on a Washington County home, pulling attic temperatures down and taking real load off the air conditioner from May through September.

Closed-Cell Spray Foam

Dense, rigid, R-6 to R-7 per inch spray foam that St. George Foam runs across the toughest applications on our schedule - roof decks, exterior walls, crawl space perimeters, rim joists, and metal building interiors - anywhere moisture resistance and structural add-on matter as much as R-value.

Open-Cell Spray Foam

Lighter, more affordable spray foam built for interior wall cavities and attic floors, where air-sealing and sound control matter more than raw density - and where St. George Foam specs it deliberately, not as a discount substitute for closed-cell.

Exterior Wall Spray Foam

Open-cell or closed-cell foam sprayed into exterior wall cavities on new-construction framing and open-wall remodels, sized to hit IECC Climate Zone 3B performance targets without over-building the assembly.

Crawl Space Spray Foam

Closed-cell spray foam applied to crawl space perimeter walls and rim joists, sealing the vented crawl space out of the thermal envelope and cutting off one of the more overlooked energy-loss points in a Washington County home.

Garage & Shop Spray Foam

Spray foam for attached garages, detached shops, RV garages, and home workshops across Washington County, aimed at turning a space that's unusable half the year into one you can actually work, park, or train in year-round.

Commercial & Metal Building

Closed-cell spray foam engineered for metal buildings, warehouses, and commercial shops across Washington County - stopping panel condensation, cutting HVAC load in large-volume spaces, and dampening monsoon noise on metal roofs, work most residential-only crews in this market don't take on.

Removal & Correction

St. George Foam removes and corrects failed spray foam installs from other contractors - off-ratio chemistry, wrong product for the application, missing code-required coatings, and lingering odor complaints - and re-sprays it right.
