Exterior Applications

Seal Tech Insulation provides high-performance spray foam solutions for commercial exterior walls, delivering superior energy efficiency and moisture protection.

We apply closed-cell spray foam in the cavity of brick-over-block walls, using brick ties to ensure a minimum 2″ depth. This seamless layer acts as insulation, vapor barrier, and moisture plain in one. With an R-value of 14 at 2.25″, it’s durable enough to withstand up to six months of exposure without degradation.

For retrofits, our CFI Injection Foam fills 8″ or 12″ block walls from the interior or exterior, providing R-values up to 18 without major structural changes.

From new builds to upgrades, Seal Tech delivers smart, efficient exterior insulation solutions built to last.
