The Intumescent Plugs provide high performance fire resistants to door mechanisms.
The plugs are located in holes drilled through hinges, striker plates and pivot mechanisms
Two 7mm diameter plain holes are drilled through each plate in addition to the existing screw holes. These holes are offset in order that the plates are not weakened. After fitting the hinges, 6mm diameter x 40mm deep holes are drilled, through the plain holes, into the wood and plugs are inserted flush with the hinge plates.
The layout of the countersunk holes for fixing screws in 100mm butt hinges varies according to the manufacturer. Three of the most common are shown here, together with suggested positions for Sealmaster Intumescent Plugs.
Where plugs have to be fitted to longer butt hinges this must be at the rate of two extra plugs per 50mm of additional length of hinge.
FEATURES & BENEFITS
Fire doors may be vulnerable to the intense heat transferred through the mass of metal that door hinges and latch plates represent. This can cause charring and ignition. Intumescent plugs, comprising a short length of metal tubing filled with intumescent material, are used to protect these ares by preventing the passage of flaming or hot gases by smothering the surrounding areas on activation.
