Mineral Fibre Sheet

Application: Fire resistant applications
Expansion Performance: 10:1 – 20:1

Pyroplex® Mineral Fibre Sheet has been specifically designed for use in fire resistant doorset assemblies, essential ironmongery such as locks, latches and concealed door closing devices. The product is supplied in two thicknesses 0.5mm and 1.0mm. When exposed to elevated temperatures, the product is designed to expand multidirectionally filling cavities and voids to provide a fire resistant barrier. The product is derived from a cellulose pulp incorporating expandable graphite with additional silicate fibres acting to aid char stability. When exposed to elevated temperatures, the material will expand up to 20:1 of its original volume producing a high resistant char.

  • Multidirectional expansion
  • Stable and durable char providing a thermal barrier
  • Easy to cut, fold and die stamp for shapes
  • Supplied on a roll

Pyroplex® Mineral Fibre Sheet can be used in the following applications:

  • Architectural fire resistant door protection:
  • Can provide a simple and concealed protection for associated door hardware. During a fire situation, the heat generated is conducted through the hardware, which if not protected could lead to integrity and insulation failure.

  • Electrical protection:
  • Used for protection for electrical installations, typically includes electrical box protection and conduit systems and can be die cut for down-lighters.

  • Panel products:
  • Can be used for applications including panelling systems for upgrading of specialist fire doors, where the intumescent has been laminated to the core of the door and lined with a finish facing, to provide insulation of the core in a fire situation.
