HP Block

HP BLOCK® is a cementitious insulation with exceptional compressive strength (>200 psi/1379kPa), making it ideal for applications where mechanical abuse is likely. The inorganic binder will hold its shape and maintain the physical integrity of the insulation, even past 450°F, the point at which most organic binders burn off. HP BLOCK® is a water-resistant, Type IA calcium silicate block insulation, designed for applications that operate at temperatures up to 1200°F (650°C).
