Description
PROMAT PROMATECT®-250 is a non-combustible mineral bound light weight board and provides a high degree of strength and dimensional stability and fire protection to structural steel and is suitable for areas where the relative humidity is up to 85%.
It is classified A1 non-combustible according to BS EN 13501-1.
Features and benefits:
- Two-sided beam protection up to 600 mm deep and 325 mm wide.
- Board fix to angle, angle fix to wall.
- PROMATECT®-250 comprises autoclaved calcium silicate spheres (PROMAXON® is a synthetic hydrated calcium silicate in spherical form) bound in a mineral matrix.
- Off-white in colour.
- One face is smooth and ready to form a finished surface, able to receive almost any form of architectural/finish treatment.
- The reverse face is sanded.

Specification data - Rigid sheet casing systems
Support | Metal angle 50 x 25 x 0.5 mm. |
Insulation | Low density (10–30 kg/m³) glass mineral wool.Guidance for specification option: If required for acoustic or thermal performance. Not required. |
Linings | Inner and outer layers: PROMATECT®-250 board thickness determined by section factor (A/V), fire resistance period and limiting steel temperature. |
Fasteners | Fixing to metal angle: M3.5 CSK Self Tapping Screws. |
System accessories | FSi Promat Pyrocoustic® Fire Resistant Sealant.Guidance for specification option: All board abutments to surrounding structure to be sealed using PROMAT PROMASEAL® Intumescent Sealant. Designed to seal any slight gaps at interfaces between the boards and the substrate, and which have low movement requirements (±12.5%). Contains no solvents or halogen compounds. |
Fire resistance | Guidance for specification option: Fire resistance (minutes) to EN 13501-2. Insert requirements. |
Colour/ Finish | Guidance for specification option: Insert requirements. Manufacturer guidanceDecorative finishes should be applied in accordance with Promat Technical Data Sheet TDS 056 (https://www.promat.com/en-gb/construction/documentation/). |
Section factor | Maximum 350 m-1. |
Steel sections | 600 mm deep and 325 mm wide (maximum). |
Substrate | Manufacturer guidanceFor SHS/ RHS/ CHS and PFC beams, where it is not possible to fix to the underside of the flange, metal angle is fixed directly to the concrete soffit with M4 screws into metal plugs, non-combustible concrete anchors or concrete screws (by others) at maximum 300 mm centres. Fixing length to provide a minimum penetration of 30 mm into the substrate. |
Strips | Coverstrips: Thickest encasement board layer x 100 mm wide PROMAT PROMATECT®-250 coverstrips fitted behind board joints and at the start and end of the beam. Guidance for specification option: Coverstrips are not required to the bottom flanges of beam encasements. |
Third-party certification | As detailed in UL-EU Certificate No. UL-EU-01220a-CPR. Guidance for specification option: Depending on site conditions, alternative fixing methods may be required for beams and columns, one- or two-sided exposure or interface with other building elements. These fixing methods are outside the scope of current EN test methods. These recommendations are based on the principles of EN 13381-4 and given in good faith. They should be approved by the responsible designer or through independent third party assessment. |
Installation | A nominal 3 mm gap must be left between the edge of the PROMAT PROMATECT®-250 board and the solid wall. This gap must be filled with FSi Promat Pyrocoustic® Fire Resistant Sealant. |
