ThermoSeal 5G is a Next Generation two component, semi-rigid, medium density, 2 lb closed cell polyurethane foam insulation system which simultaneously insulates and air-seals your building structure.Thermoseal 5G uses the latest generation, high performance blowing agent known as Forane 1233zd HFO. Forane LBA has a Global Warming Potential "GWP" up to 99.9% of the products they replace.
