Our new ProFill HD .75/lb high-density open-cell foam is a more affordable alternative to closed cell insulation. Contractors are reporting exceptional yield, 9,000 - 10,000 board ft, compared to traditional 2.0 closed cell insulation which only gets half as much. Contractors using the ProFill HD .75/lb high-density cell open cell foam system in place of their standard 2.0/lb density closed cell foam system are still seeing a lot of the benefits of a rigid, durable, closed-cell polyurethane foam material with the added bonus of GREATER PROFITABILITY!
