ThermalGuard™ OC.4 & OC.5 Products
ThermalGuard OC.4, OC.5 & OC.5X
ThermalGuard OC.4ex is a fast set, open cell, Class 1 fire-rated spray polyurethane foam (SPF) insulation system, designed to reduce energy consumption in residential and commercial structures up to 50% by insulating and air sealing the thermal envelope in a single step. This foam exhibits superior thermal insulation, air-barrier and sound attenuation properties compared to conventional insulation materials. The lower density and higher yield work to provide more board footage per set.
ThermalGuard OC.5 is a high-yield, open cell, Class 1 fire-rated, 100% water-blown spray polyurethane foam insulation designed for use in residential and commercial walls, attics and roof decks. When applied, ThermalGuard OC.5 expands to over 100 times in size in approximately 4 seconds, filling and sealing building cavities of any shape and size. It is sprayer-friendly, offering a wide application window and temperature tolerance and excellent adhesion when installed in cold temperatures down to 15°F.
ThermalGuard OC.5 seals and insulates in one step, helping property owners reduce energy consumption by up to 50% when compared to conventional insulation systems. Its superior thermal insulation, sealant and sound attenuation properties contribute to a healthy, quiet and more energy efficient building.
ThermalGuard OC.5X has a 4.2 R-Value and is Appendix X compliant.

Open Cell Advantage
Interlocking air bubbles expand over 100 times their original size in about 4 seconds to create a soft, spongy, insulating barrier. Open cell spray foam insulation costs less per job and per R-value measurement allowing you to use much less material to cover more ground.
