Why Choose Closed Cell Spray Foam?



Superior Insulation Performance

Closed cell spray foam offers one of the highest R-values per inch, providing exceptional thermal resistance. That means better energy efficiency, lower utility bills, and stable indoor temperatures no matter the season.



Air and Moisture Barrier

This foam creates an airtight seal that eliminates drafts and blocks moisture infiltration. By keeping outside air and humidity where they belong, you’ll enjoy cleaner indoor air and reduce the risk of mold and mildew growth.



Structural Strength

Closed cell foam hardens as it cures, adding rigidity to walls, ceilings, and roofs. This extra strength increases structural durability, making it especially valuable in storm-prone or high-wind areas.



Water Resistance

Unlike traditional insulation, closed cell spray foam does not absorb water. It acts as a protective moisture barrier, helping prevent long-term water damage, wood rot, and structural decay.



Space Efficiency

Because of its high insulation value, closed cell foam delivers outstanding performance with less material. It’s perfect for tight or limited spaces where every inch counts.



Long-Term Savings

Although it costs more upfront than fiberglass or cellulose, closed cell spray foam pays for itself through reduced energy use and lower HVAC maintenance costs.



Pest Deterrence

The dense structure of closed cell spray foam discourages access for rodents and insects, adding an extra layer of protection to your home or building.
