Product information and downloads

Tested and certified for fire safety

This flame-retardant polyurethane foam is an ideal material for preventative fire safety on windows and doors. It can be used for providing an insulating seal on perimeter joints. The special foam adheres to all common building materials. If it is used between solid mineral or metallic building materials, 806 Brandschutz Kombi Schaum is rated at building material class B1 according to DIN 4102-1. In all other applications, it falls under building material class B2 according to DIN 4102-1. Once cured, the red polyurethane foam is semi-hard, predominantly closed-cell and moisture-resistant.
