Product Overview

Providing at least 60 minutes of protection against the spread of fire, these fire-only seals are designed for FD60 fire doors and frames with 20mm rebated seal channels. The seals are made of an intumescent material which swells when exposed to high temperatures to fill any and all gaps around a fire door leaf and come with self-adhesive backing for quick installation.

  • Certifire approved to BS 476 Part 22
  • Must only be fitted by a fire door professional and to doors with certification that allows retroactive rebating
  • Fire rated for 60 minutes and suitable for FD60 doorsets
  • Available in white or brown
  • Suitable for 20mm rebates in the door leaf or frame
  • Available in single or double door kits:
    • Single door kit - 5 strips of 1.05m x 20mm x 4mm (LxWxD)
    • Double door kit - 8 strips of 1.05m x 20mm x 4mm (LxWxD)
  • Intumescent material reacts to high temperatures to swell and block the spread of fire
  • Self-adhesive backing for easy fitting
  • Also available separately with brushes to prevent smoke penetration
  • For fire doors that do not have rebates, please use surface mounted fire and smoke seals instead
