What is BioBased 501w?
BioBased 501w is an open-cell, semi-rigid foam insulation. It is sprayed-in-place as a two-part polyurethane. Once applied, it expands to 100 times its original size and provides a sealed, thermal building envelope. BioBased 501w, like all BioBased Insulation products, was formulated with the environment in mind and utilizes annually renewable resources to replace some of the petroleum in the product. The product also is water-blown, which means it does not contain CFCs or HCFCs.
