Pyrocloser Intumescent Kit

Where fire resistance is concerned, concealed door closer mechanisms are an obvious weak point in any timber door and in the event of a fire, they can have a seriously detrimental effect on the integrity of both door and frame.

By fitting Pyrocloser intumescent kits, this problem can be simply overcome, providing a high performance intumescent gasket that will insulate the timber, slow the charring process and enhance the fire resistance to a more acceptable level.

  • Minimum proven fire resistance of 30 minutes
  • Wide choice of templates to fit well known brands
  • Colours available: White, Brown & Black
  • Non-standard sizes available on request
  • Easily cut to size and fitted to both external and internal closers
  • Holes, cut-outs and notches incorporated if required


Intumescent kits are available for leading manufacturers of concealed door closer mechanisms, including:

  • Geze
  • Hoppe
  • Rutland
  • Allgood
  • DormaKaba
  • We can also manufacture kits to suit other brands of hardware
