Polyurethane Thermal Column Bearing Blocks

Product Description

JP Series Column-Bearing Blocks are a high density, high-compressive-strength polyurethane foam that is installed between the concrete foundation and steel columns. The blocks provide a thermal break between the building interior and the supporting soils below as specified by architects and engineering professionals.  We have been manufacturing blocks for this application for over 10 years.
