REX Flaton VPG 12 fire protection board is a predominantly inorganic intumescent material that foams up in the event of fire or heat exposure at a temperature of 180°C and above. The volume increases by at least 4.5 fold. Usually 11 fold. This creates an extremely effective barrier against smoke, fire and heat.
