The closed-cell foam will not collect moisture. Mold and mildew cannot grow and spread without moisture. Controlling your home’s environment and air quality is easier with spray foam insulation.


Spray foam insulation seals the cracks that allow pests to penetrate a home. Ants, roaches, crickets, fleas, ticks, ladybugs, mice, and rats all struggle to access a home insulated with spray foam insulation.

Choosing the right type

Flexible foams or open cell foams?

If the foam expands far enough, an open celled configuration will develop, like a sponge. These are referred to, as flexible foams or pour/ froth foams. Good for spraying roof lines and 2x6 walls in new home construction.

Rigid foams or closed cell foams?

If the gasses become trapped in the cell structure, a closed cell configuration is formed. These foams have excellent insulation properties and are called rigid foams. Rigid foams can be either poured or sprayed and are used in structural foams,fabric backing, or building and packaging industry and other applications. Excellent for all types of insulating application.
