Intumescent Hinge Liners are positioned behind the leaves of hinges on fire rated timber doors. In the event of a fire, the liners expand to seal the door at the hinge points and prevent the ingress/egress of hot gases. These self-adhesive liners are suitable for all of our Stainless Steel FD30/FD60 rated fire door hinges and can be easily trimmed on site for various leaf widths/heights.
One pack is sufficient for one pair of hinges (1 liner for each hinge leaf).
Important: ALL single-axis butt hinges certified as being suitable for use on fire doors will normally have been tested with the inclusion of intumescent material behind the hinge leaves on both door and frame (this will be stated on product test certificates). Where this is the case, and where certified hinges do not incorporate pre-fitted liners, intumescent pads of the correct rating MUST be fitted to ensure full compliance with the relevant standard.
These hinge liners are intended for use only with appropriate hinges that have been successfully type tested for conformity to all of the requirements of BS EN 1935 : 2002 including the additional requirements for fire/smoke door use.
