Performance Foam Tech is the solution for all your insulation needs -We specialize in spray foam insulation - a closed cell (rigid) polyurethane foam that is sprayed by the inch. Sprayed in place, it stops air infiltration - outside air cannot come in and inside air cannot leak out - creates a monolithic vapor barrier and thus eliminates condensation in your walls, ceilings and floors. The result is NO mold and NO mildew.
