Application

  • For the protection of hot-rolled structural steel.
  • Suitable for internal and unheated spaces.

Description

Promatect-XS is A1 non-combustible to EN 13501-1, and third-party classified to provide 60 minutes fire resistance. It installs quickly due to its minimal framing and holds its own for up to six months exposed on site. Its junction details are fire tested so the edges are as robust as the face.

Features and benefits:

  • Fire resistant: A1 non-combustible board to EN 13501-1.
  • Bespoke junction testing: for interfaces between encasements and partitions.
  • Rapid and easy to install: minimal framing components required. Direct fix using staples.
  • Third-party certified: EN tested and classified to achieve 60 minutes fire protection to EN 13501-2.
  • Moisture resistant: can be left exposed for up to six months, subject to specific conditions.
  • Maintains compartmentation: additionally tested for fire integrity and insulation.
  • High quality surface finishing.

Moisture resistance

Guidance for specification option:

Promat PROMATECT®-XS is resistant to the effects of moisture and will not physically deteriorate when used in damp and humid conditions. It can be installed up to 6 months before the building is weathertight, subject to the following conditions:

  • Board must not be subjected to standing or pooling water, or water run-off from slabs or other parts of the building.
  • Where the board is located on the perimeter of the building and sits proud of the building line, exposed surfaces should be suitably protected with a breather membrane.
  • To protect from driving rain, a bead of FSi Promat Pyrolastic® Silicone should be applied at the cut edges after the boards are butted together and smoothed over the joints and exposed edge.
