The high-density rigid cellular polyurethane blocks are designed to support structural loads while insulating buildings. Cellular polyurethane is a natural insulator, and formulated in these high-density blocks, it provides the strength to support large compressive loads with little deflection. At the same time, it offers economical, code-required continuous insulation that reduces loads on cooling equipment for lower energy costs.

A wide range of compressive strengths satisfies industrial and cold-storage thermal construction applications.

This series extends the building insulation envelope from the roof to the foundation below ground. Even at the high densities required for support of column-bearing loads and precast/tilt-up wall panels, these blocks will provide thermal insulation value superior to lightweight concrete, treated wood blocks, and other traditional materials. They are commonly used as thermal isolation load-bearing blocks in concrete footings within refrigerated warehouse structures. As insulated structural support for roof equipment, roof perimeter fall protection and chiller tanks, they minimize both thermal transfer and condensation.

These blocks are delivered to contractors ready to use. They arrive at the jobsite cut-to-size, predrilled with anchor-bolt holes, and marked for fast and easy placement. This eliminates waiting for cutting or drilling before moving onto the next construction step, saving precious time.
