Polyfoam SS‑45A is a two‑component, spray‑applied polyurethane foam that forms a rigid, monolithic barrier against water vapor and air. It is HCFC‑ and CFC‑free and produces a foam with a nominal density of about 43‑48 kg/m³ when applied. The system is used for gap and void filling and sealing around construction elements such as window and door frames.
