Firestop
Firestop is a UK manufacturer specialising in passive fire protection products for doors and hardware, best known for intumescent seals and intumescent “hardware protection” kits that help fire doors keep their integrity when exposed to heat and smoke. They position the brand around “protecting life and property,” with 25+ years of experience supplying the UK and overseas markets.
What Firestop actually makes (the stuff you’ll see in the trade channel):
-
Intumescent fire & smoke seals (the strips that expand in a fire to close the gap between door and frame).
-
Intumescent ironmongery protection: sheets/pads/liners used behind or around items like hinges, locks, latches and closers to maintain the fire-rating of the door set.
-
Fire-rated ironmongery items such as intumescent letter plates and door viewers, designed so adding openings to a fire door doesn’t ruin the door’s performance.
-
Often also stocked as drop-down door seals and related door-bottom sealing hardware for fire/smoke control and acoustic performance.
A detail they stress is traceability: Firestop highlights a traceable production code / certification approach so installers/specifiers can link products back to compliance evidence and batch provenance.
