Premium Spray Products


Premium Spray Products, Inc. Foamsulate™ 50 is a two component, one to one by volume spray applied polyurethane foam. To produce Foamsulate™ 50 requires the use of an “A” component (ISO) and a blended “B” component (RESIN) which contains ZERO Ozone Depleting blowing agents, catalysts, polyols and fire retarding materials.

Foamsulate™ 210 is a 2.0 LB density closed cell insulating material. Foamsulate™ 210 is designed for use where insulation systems require superior air barrier characteristics along with the ability to minimize moisture infiltration. Foamsulate™ 210 has a 6.8 per inch R-value rating while providing structural enhancement due to its rigid nature when cured. When properly installed by a trained contractor Foamsulate™ 210 quickly expands to fill the cracks, crevices, gaps and voids that exist in every structure. In addition Foamsulate™ 210 will conform to the curves, irregular surfaces and spaces to form a superior thermal envelope around your entire structure.

Dow Styrofoam SPF

As a component of the THERMAX™ Wall System, STYROFOAM™ Brand Spray Polyurethane Foam (SPF) (CM Series) creates a seamless, monolithic barrier on the interior of steel stud walls. The spray foam effectively blocks air infiltration by filling gaps, cracks and penetrations, and provides additional insulation. This closed-cell, two-component, 2.0 pcf spray foam successfully incorporates the Enovate 3000 blowing agent from Honeywell.

Other Items:

FROTH-PAK™ is a two-component polyurethane spray foam that comes in both portable kits and refillable tanks. It is available in multiple densities and is ideal as an insulator or air-sealant. GREAT STUFF Pro Window & Door foam sealant is exclusively formulated to air-seal the gap between a window or door frame and its rough opening. It expands only enough to generate an effective seal, and makes window and door systems more energy efficient. Pur Fill 1G is a moisture-curing foam that expands in place to bond and seal holes and gaps, stopping the passage of air, gases, water, dust, fibers, sound, rodents, pests, radon and odors. Our professional gun dispensers have the added features of complete control, no messy clean-ups or wasted foam.
