Function and usage:
Vermiculite board has good fireproof and will not burn, meaning they are safe and efficient products. They have an anti-combustible fire rating of A1, which is the maximum possible. They are chiefly used in public buildings which need to be comprehensively fireproofed ie. Hotels, offices, shopping centres, schools, laboratories, hospitals and many other municipal public buildings.
Because of their fireproof properties, they work well as the core of a fireproof door. They severely reduce the risk of the building catching fire and fire being able to progress from room to room.
