Tecnofire for Gap Filling

Due to it's highly unidirectional expansion TFP's Tecnofire® range is the ideal fire protection solution for a broad selection of traditional gap filling applications. These include:

  • Pipe wraps and collars
  • Door edge seals
  • Glazing seals
  • Joint seals for building panel systems
  • Grilles and vents
  • Ironmongery protection
  • Linear gap seals


Tecnofire® is a unique range of mineral fibre stabilised, graphite-based intumescent materials. They contain exfoliating graphite, high temperature resistant mineral fibre, a small amount of organic binder and, in some cases, additional particulates, fibres or active ingredients. 

Tecnofire® expansion is activated by heat (>190°C), this expansion produces an inert char that is highly stabilised by a matrix of mineral fibre and acts as an insulating layer to offer enhanced fire protection to any underlying materials.  Tecnofire® is available in a wide range of thicknesses (0.5mm up to 5mm) and expansion ratios (4.5:1 up to 35:1) as well as in both flexible and rigid forms. The materials can be supplied as continuous rolls, sheets or custom cut shapes depending on requirements and secondary processing options, such as addition of self-adhesive backing and surface sealing or coating, are also available.
