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:

One-sided column protection up to 600 mm wide.
Direct fix to column.
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	N/A.
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. Guidance for specification option: Minimum PROMAT PROMATECT®-250 thickness for compartmentation on both sides of steel (when one-sided fixing detail is applied to both sides of the steel): 60 minutes: 15 mm; 90 minutes: 20 mm; 120 minutes: 25 mm. Where protection to the structural steel and compartmentation are required, thicker of the two boards should be used. Manufacturer guidance For double layer encasements joints between layers must be staggered by minimum 530 mm. Boards can be left untreated or painted; where decorative finish is required, see Colour/ finish below. Board thicknesses over 25 mm are installed as a double layer, board joints between layers staggered by 530 mm minimum.
Fasteners	Fixing to steel column: M4 CSK self-drilling screws or 3.7 mm shot-fire nails. Guidance for specification option: At maximum 200 mm centres (staggered). Screw length to provide minimum penetration of 10 mm through the steel section. Screws to be position between 25 mm to 85 mm from the edges of the concrete or blockwork wall. Manufacturer guidance See also Installation below.
System accessories	FSi Promat Pyrocoustic® Fire Resistant Sealant.

Fire resistance	Guidance for specification option: Fire resistance (minutes) to EN 13501-2. Insert requirements.
Colour/ Finish	Guidance for specification option: Insert requirements. Manufacturer guidance Decorative 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	Up to 600 mm wide.
Strips	N/A.
Third-party certification	As detailed in UL-EU Certificate No. UL-EU-01220a-CPR. Guidance for specification option: Note: 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	For one-sided column encasements boards are fixed directly to the to the steel. 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.
