Knauf Acrylic FPA

Knauf Fire protection acrylic - FPA is designed to prevent the spread of fire and smoke through joints and openings in fire rated walls and floors including openings formed around building service penetrations. It will also maintain the acoustic design performance in walls and floors. Knauf Fire protection acrylic FPA cures when it is subjected to atmospheric conditions, however it will retain a degree of elasticity for joint movement. Under fire exposure FPA creates a robust fire seal by the formation of a durable intumescent char. Thermal activation takes place at about 180°C when the material will expand and prevent the passage of fire and smoke for up to 4 hours.
