thermalstone wooltube

Tie-rod fire protection cupels AF PSR 120 cupels consist of two concentric bodies made of high density rock wool. The inner cupel is treated on the surface with a special product to lower temperatures using water vapour emission. AF PSR 120 cupels are designed for fire protection of structural steel elements and tie rods. The outer cupel is coated with a layer of aluminium mesh or galvanised sheet metal that can be fixed with self-tapping screws. For some applications, where fire resistance for 60-90 minutes is sufficient, AF PSR 90 cupels are available. These are high density rock wool cupels with a surface coating of wire aluminium foil.
