Intumescent Grills
Description
Fireplug FPG and FPCG intumescent grills are manufactured using Firefly type 105 intumescent Honeycomb and are supplied within a metal surround.
Fireplug FPG are available for 1/2, 1 and 2 hour doors and 2 hour duct ventilation. 
Fireplug FPCG can be supplied as an integral component of a female coupler (MCF) or male coupler (MCM) or with it's own metal surround for standard sizes 100mm and 150mm circular, for up to 2 hour protection.

If face plates are required they are normally supplied louvered i.e. non-viewing.  This means when ordering state clearly height and width to ensure louvres run in the correct fashion.  Fireplug FPG grills come in a full range of sizes.
Free airflow has been calculated to give a minimum of 70%, with grills of 300 x 300 giving in excess of 80%.
Action
Under the action of heat, the honeycomb openings seal up to prevent the passage of hot gases and toxic fumes.
