Arizona’s Trusted Experts in Closed-Cell Spray Foam

What Is Closed-Cell Spray Foam?

Closed-cell spray polyurethane foam (SPF) is a high-density insulation and air barrier system. It expands upon application to seal cracks, gaps, and voids, creating a rigid, durable surface that bonds to wood, metal, concrete, masonry, and most roofing substrates.

Unlike traditional insulation, closed-cell foam is waterproof, structurally reinforcing, and offers a superior R-value per inch—making it ideal for Arizona’s extreme temperatures.

Application of Closed Cell Foam

​

Why Choose Closed-Cell Foam?

✅ Maximum Energy Efficiency

Closed-cell foam has an R-value of 6.5 to 7 per inch, which helps maintain indoor comfort and reduces heating and cooling costs year-round.

✅ Moisture Barrier

Unlike open-cell foam or fiberglass, closed-cell foam acts as a vapor retarder, helping protect your structure from mold, rot, and moisture damage.

✅ Structural Strength

Closed-cell foam adds rigidity to walls and roofs, improving durability against wind, vibration, and settling—perfect for flat roofs and metal buildings.

✅ Seamless Air Seal

Every inch is sprayed directly onto the surface, sealing even irregular shapes and hard-to-reach places—eliminating drafts and improving air quality.
