Closed-Cell Spray Foam in Katy, TX
Closed-cell spray polyurethane foam is the highest-performing insulation product available for Katy's humid Gulf Coast climate. At R-6.5 per inch, it delivers more insulating value per inch than any other product, while simultaneously acting as an air barrier and vapor retarder. For moisture-exposed assemblies, metal buildings, and crawl spaces, it's the definitive choice.

What Makes Closed-Cell Different
Closed-cell foam gets its name from its cellular structure — billions of tiny closed cells that trap insulating gas inside and prevent moisture and air from passing through. Unlike open-cell foam (or fiberglass), closed-cell foam doesn't absorb water, doesn't allow moisture vapor to pass through at typical thicknesses, and doesn't compress or settle over time.
Highest R-Value
R-6.5 per inch means you achieve R-13 in just 2 inches — critical where space is limited.
Built-In Vapor Retarder
At 2 inches, closed-cell foam meets IRC vapor retarder requirements for Climate Zone 2A. No poly sheeting needed.
Complete Air Barrier
Stops air infiltration in all directions — more effective than any other insulation type.
Structural Contribution
Closed-cell foam adds racking strength to wall panels and roof structures — documented in testing.
No Moisture Absorption
Closed-cell foam exposed to flooding or high humidity doesn't absorb water and doesn't lose R-value when wet.
Permanent
Doesn't sag, settle, or degrade. A closed-cell installation is a lifetime upgrade.
