The Highest Performance Insulation Available
Closed cell spray foam is the gold standard of insulation — delivering the highest R-value per inch, a built-in vapor barrier, and structural reinforcement all in one application. The only real choice for metal buildings, crawl spaces, and condensation problems.
Closed cell spray foam is made of cells that are fully closed and packed together — creating a dense, rigid material that is completely impermeable to air and moisture. When cured, it's hard to the touch and adds measurable structural strength to walls and roofs.
At R-6.7 per inch, it delivers more than double the insulating power of open cell. It's the only insulation that acts as both an air barrier AND a vapor barrier — making it non-negotiable for metal buildings, crawl spaces, and Florida's humidity.
The ONLY solution that stops condensation on metal panels. Adheres directly to steel, eliminates dripping, prevents rust from the inside, and adds structural rigidity. Non-negotiable for Florida metal structures.
Vapor barrier is critical in crawl spaces. Closed cell on walls and rim joists completely seals the most common air leak in Florida homes — stopping moisture, mold, and pests at the source.
Extreme temperature swings create relentless condensation on steel container walls. Only closed cell sprayed on all interior surfaces eliminates it completely — and stops off-gassing from used containers.
R-6.7/inch in standard 2x4 walls delivers R-21+ — beating blown-in and batt by miles. Adds structural reinforcement, a vapor barrier, and a permanent air seal all at once.
Maximum performance attic encapsulation. The higher R-value means thinner application needed. HVAC in conditioned space, zero humidity infiltration, and a sealed attic that performs for the lifetime of the home.
Commercial roof deck encapsulation with closed cell delivers the best energy ROI of any commercial upgrade. Many large buildings see $3,000–$8,000/month in savings — paying back in 2-3 years.
