Features & Benefits

  • Used in steel doors, wood doors, and partitioning to provide up to 65 minutes fire protection
  • Strips are fitted to beads each side of the fire-rated glazing
  • The 2mm thick seal can be compressed to 0.5mm to fit smaller gaps without compromising its performance


The strips are fitted to beads each side of the fire rated glazing. Although the seal is 2mm thick, it will compress to 0.5mm while not affecting its performance. For 30 minutes glazing 10mm or 15mm beads must be fixed with 36mm panel pins at 200mm centres. For 60 minute glazing 20 – 25mm beads using 60mm No8 CS steel screws at 200mm centres to fix. Grip the self-adhesive backing strip and separate the protective paper from the adhesive. Pull along for a few centimetres to expose the adhesive surface ready for adhering onto the glazing beads. Attach the intumescent strip to the face of the bead, peeling away additional backing paper as necessary. Fix beads in place with the glazing strips towards the glass.
