Pyrostone holds its shape extremely well and even at high temperatures maintains its stability, stiffness, flame retardance and fire-resistance. It is non-reactive when hardened and can be transported without causing harm to the environment. A high degree of moisture resistance, adherence and screw fixation strength make the characteristics for Pyrostone complete. In short: the ideal material for every type of fire resistant door construction!

Pyrostone is a FRP (Fibre Reinforced Plastic). The product consists of mineral fibres in a thermosetting polymer (epoxy) with an SG of approximately 1.1 kg/dm3. It is applied to the wood in a double component system and hardens fully within 12 hours.
