- Suitable for semi-exposed and unheated spaces.
Description
Promat VERMICULUX®-S is a non-combustible calcium silicate board reinforced with selected fibres and fillers, is resistant to the effects of moisture and will not be subject to physical or performance deterioration when used in damp or humid conditions. The strong rigid board can be installed before the building is watertight. It is classified A1 non-combustible according to BS EN 13501-1. Promat VERMICULUX®-S is off-white in colour and has a smooth sanded surface on one face with a lightly honeycombed texture on the reverse face.
Up to 240 minutes fire resistance can be achieved depending on the thickness of material used, the dimensions of the steelwork being protected, the number of layers used and the limiting temperature of the steel section.

Specification data - Rigid sheet casing systems
Support | Metal Angle 50 x 25 x 0.5 mm and 3.7 x 16 mm Shot-fire nails or M4.2 x 12 mm self-drilling self-tapping wafer head screws.Guidance for specification option: Casings are installed using metal angles fixed to the underside of the top steel flange for I-beams, offset by a minimum of 3 mm from the flange egde, angles fixed to the soffit for SHS/RHS/CHS and PFC beams. Manufacturer guidanceFor beam widths over 325 mm, use minimum 25 x 25 x 25 x 0.65 mm Z-sections to support soffit boards, fixed with 3.7 x 16 mm Shot-fire nails or M4.2 x 13 mm self-drilling self-tapping wafer head screws. |
Insulation | Low density (10–30 kg/m³) glass mineral wool.Guidance for specification option: If required for acoustic or thermal performance. |
Linings | Inner and outer layers: Promat VERMICULUX®-S board thickness determined by section factor (A/V), fire resistance period and limiting steel temperature. Maximum board length 1200 mm.Guidance for specification option: Minimum Promat VERMICULUX®-S thickness for compartmentation on both sides of steel: 60 minutes: 20 mm, 90 minutes: 25 mm, 120 minutes: 30 mm, 180 minutes: 40 mm, 240 minutes: 50 mm. Where protection to the structural steel and compartmentation are required, thicker of the two boards should be used. Insert requirements. Manufacturer guidanceFor double layer encasements the thicker board should be applied as the inner layer and joints between layers must be staggered by minimum 600 mm. Boards can be left untreated or painted. Board thicknesses over 40 mm are installed as a double layer. |
Fasteners | Fixing to Metal Angle: Minimum M3.5 CSK Self Tapping Screws. |
System accessories | FSi Promat Pyrocoustic® Fire Resistant Sealant.Guidance for specification option: Designed to seal any slight gaps at interfaces between the boards and the substrate, which have low movement requirements (±7.5%). Contains no solvents or halogen compounds. |
Fire resistance | Manufacturer guidanceFire Resistance (minutes) to BS 476-21. Insert requirements. |
Colour/ Finish | Manufacturer guidanceDecorative finishes should be applied in accordance with Promat Technical Data Sheet TDS 056 (https://www.promat.com/en-gb/construction/documentation/) and the Promat Passive Fire Protection Handbook (https://www.promat.com/en-gb/construction/tools-services/fire-protection-handbook/) |
Section factor | Maximum 275 m-1. |
Steel sections | 609 mm deep and 325 mm wide (maximum). |
Substrate | Manufacturer guidanceFixing to substrate: For 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 Minimum M4 screws into metal plugs, non-combustible concrete anchors or concrete screws (by others). |
Strips | Coverstrips: 20 mm thick x 120 mm wide Promat VERMICULUX®-S coverstrips fitted behind all board joints. |
