Intumescent strips for use in fire resistant timber door leaves and frames. The brush and flipper options provide additional smoke and acoustic protection.
They come in 2.1m lengths in a range of widths (10mm, 15mm and 20mm) depending upon the required fire resistance (30 minutes or 60 minutes). A choice of white, brown, and black with a self-adhesive backer for easy installation.
They are suitable for new build and retro-fit applications.
Intumescent strips are placed around the perimeter of the doorset on three edges between the frame and the door. A drop down seal can be fitted to the bottom of the door if required. In the event of a fire, the extreme heat causes the fire door strip to expand and seal the gap between the door leaf and the frame. This contains the fire and allows enough time for people to evacuate the building.
