ThermalGuard™ CC2



ThermalGuard CC2

ThermalGuard CC2 is a closed cell, 245fa-blown spray polyurethane foam insulation that achieves exceptional yield and adhesion in a wide range of ambient conditions and applications. When applied, ThermalGuard CC2 expands to 25 times its size in approximately 12 seconds to seal and insulate. It can safely be applied in lift thickness of up to 4 inches in a single pass with excellent control and a smooth finish, achieving Appendix X compliance without any additional coatings.

ThermalGuard CC2 is designed for use in wall, attic, and roof deck applications where it insulates, air-seals and adds structural strength. It’s also suitable for a tank and pipeline insulation and as a below-grade exterior insulation for foundation walls or slabs. ThermalGuard is Class 1 fire rated and has an R-value of 6.85 per inch.

Added Structural Support

ThermalGuard CC2 is densely packed closed cell spray foam, which makes it more rigid and stronger than conventional insulation systems and even open cell SPF insulation. With very high tensile and compressive strengths, ThermalGuard CC2 provides the benefit of added structural support to a building’s walls, roof, and foundation. Its high density also creates a greater barrier against the penetration of moisture, making it great for below ground installations.
