This Black intumescent Fire Door Seal prides itself on being a very simple & safe option that is an ideal match for many of the Internal Black Fire Doors we offer from Liberty Doors. In the event of a fire these intumescent fire strips expand in size causing them to seal off the gap between a door & its frame, blocking smoke & heat from passing through & thus providing protection from the spread of a fire for its rated duration
This fire door lining set has been Certfire rated with them being tested for 30 minutes of integrity, this means that these intumescent seals are suitable for any FD30 fire rated door, allowing them to provide a critical boost to protection against the spread of a fire. Additionally this fire seal is supplied with self-adhesive backing tape to ensure a simple installation.
