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.
Our range includes a comprehensive selection of Firestop passive fire protection products, designed to maintain the critical integrity of fire doors. This collection focuses on preventing the spread of fire, smoke, and heat through essential door hardware apertures.
Our Firestop selection covers two key areas:
- Intumescent Strips & Seals: This includes self-adhesive universal hardware protection kits designed to wrap around deadlocks, sashlocks, dinlocks, and tubular latches. We also supply high-performance automatic drop-down seals - such as the Applic, Superior, and Trend models - which lower automatically to block draughts, sound, and smoke at the bottom of the door.
- Fire-Rated Door Furniture: This range features telescopic intumescent letter plates and wide-angle 180° door viewers, engineered to preserve the fire rating of FD30 and FD60 doors.
Whether you are retrofitting existing doors or completing a new installation, these easy-to-install solutions help keep your premises safe, compliant, and secure.
