Foams and thermally insulates
Palstop P starts to foam under high pressure ( 0,9 N/mm²) at a temperature of 100 °C. In short time the board thickness can increase up to seven times. It creates a non-flamable, thermally insulating and pressure stable sealing material. This material closes gaps, seams and construction element conduits. Thus no hot gases and flames can penetrate. Due to the porous structure of the foamed material it has a very good thermal insulation. Additionally during the foam process a cooling effect occurs that works against a fast rise of the surface temperature of the protected building element.
