Firestop Intumescent Fire & Smoke Seal White 15 x 4 x 1050mm 5 Pack Product Code: 21295

1.05m Lengths. 15 x 4mm. Intumescent fire seals expand in the event of a fire and seal off the gap between the door and the frame, preventing the spread of fire and smoke. This combined fire and smoke seal prevents the spread of smoke prior to the fire seal activating. Features low friction brush pile to aid door closing. For maximum effectiveness, they need to be rebated into either the door frame or the door itself. It is very important to fit the correct size seal, please always check fire door manufacturers instructions. As a guide, only use 15mm seals on new door application and 10mm seals for replacement / retrofitting.


W x D: 15 x 4mm. BS 476-22, CF 846.

Rated 4 out of 5 by from Fire & Smoke Intumescent Seal These intumescent seals were good quality and installed easily. Needed to install on FD30 Fire doors required by Buildings Control.

Rated 4 out of 5 by from Did the job! Would buy again. easy to fit. just need something sharp to cut and a hammer to knock into place.

Rated 5 out of 5 by from fire strip Easy to use, you don't need the draft excluder bit because the intumescence strip swells to close any gaps when it heats in a fire. Because the door was subject to drafts i chose the draft excluder option. You may need to give it another 1mm of leeway when fitting it because the fit might be too snug.

Rated 4 out of 5 by from Good solution Fitted some of theses strips to a firedoor without any problems, although they're only 1m long so there is an issue with having to add/cut to make up the seals. A nice addition to the pack would be some kind of shims which would allow to adjust the gap.
