AF PSR 90-120

AF PSR 120 cupels consist of two concentric bodies made of high-density rock wool. The internal cupel is coated with a product which lowers the temperature by releasing water vapour. AF PSR 120 cupels are designed for fire protection of steel structural elements, particularly tie rods.

On request the external cupel can be covered with a layer of wired aluminium or galvanised sheet that can be locked with self-tapping screws.

For applications where fire resistance needed is for 60-90 minutes, AF PSR 90 cupels are available. These are high density rock wool cupels externally coated with wired aluminium foil.
