Intumescent seals
Intumescent door seals are designed to close the gap between the fire door and frame in the event of a fire, thereby preventing the spread of smoke and hot gasses
Essential components for fire doors
Our range of perimeter seals has been curated to offer solutions for a wide range of gap sizes, fixing locations and applications. This includes rebated, self-adhesive and surface-mounted options for both door stops and frame reveals. Some seals act as compression seals, shaped so that they compress against the door when it is closed. Others perform as a sweep seal, sweeping against the door edge as the door moves into a closed position.
The athmer range includes seals that can be used at the head, jambs and the meeting stile of doors. There are solutions for hinged and sliding doors as well as for timber, metal and glass surfaces. Their main purpose is to provide an effective barrier against sound transfer between the door and door frame, as well as smoke, air, light, dirt, dust and odours. They can also effectively muffle door closing noise. They are the perfect accompaniment to our range of drop seals and an essential component in an acoustic door assembly targeting acoustic performance.
