Rigid Foams

LAST-A-FOAM® rigid CFC-free polyurethane foam boards and products are cost-effective, versatile, strong and durable. They are manufactured using our unique chemical formulas to be exceptionally uniform and consistent in all physical properties. You will find a wide spectrum of formulations in multiple densities. Our rigid foam materials are available in sheets or blocks.

POLYURETHANE FOAM SHEETS & BLOCKS


Our high-density, flame-retardant, marine and rigid polyurethane foams are also available in a broad range of physical forms, including rigid and hard foam boards and blocks. This allows us to best align HDU foam properties with your specific needs – and help you contain material and manufacturing costs.
