Closed Cell Spray FoamClosed-cell foams resist water penetration and moisture build-up. Moisture can eventually attract bacterial growth, promoting mold, which can eat away at wood and compromise structural integrity.- Open Cell Spray FoamOpen-cell foam is characterized as being composed of many air bubbles held within a polyurethane matrix. As with many insulation’s such as fiberglass, it is this trapped air that lessens the heat transfer through the foam.
- Retrofit Foam InjectionRetrofit Foam is identical to our open cell spray foam, except that the expansion reaction is slowed down
- Spray Foam RoofingBecause the foam is sprayed onto the roof as a liquid, it forms a single continuous membrane that is seamless and very stable.
- Concrete Slab InsulationInsulating under foundation and basement slabs using spray polyurethane foam offers certain advantages.
- Blower Door TestingWe use blower door testing to check building tightness and air infiltration.
