Classification data
Support	None.
Linings	Outer layer: Promat VERMICULUX-S (refer to steel schedule for thickness). Inner layer: Promat VERMICULUX-S (refer to steel schedule for thickness). Manufacturer guidance Facing notes: maximum board length for column encasements is 2500 mm.
Fasteners	Board to board: high thread drywall screws at maximum 200 mm centres. Guidance for specification option: High thread drywall screws at maximum 200 mm centres, length determined by board thickness, minimum 30 mm screw penetration into board.
Joint treatment	Cover strips: none required. Manufacturer guidance Board joints on adjacent faces must be staggered by minimum 500 mm within each layer at maximum 2500 mm centres and staggered between layers by minimum 400 mm.
Steel sections	600 x 600 mm (maximum). Guidance for specification option: Dependent on board thickness and limiting temperature (refer to steel schedule for thickness). Manufacturer guidance Depth x width.
Fire resistance	Up to 240 minutes to BS EN 13381-4 and BS EN 13501-2. Guidance for specification option: Depending on board thickness, steel size and limiting temperature (refer to steel schedule for thickness). Manufacturer guidance Certifire CF 5757 and classification No. WF 554072B. Limiting temperatures: Min. 300°C, Max. 700°.
Weather performance	Exposure up to 6 months. Guidance for specification option: Promat VERMICULUX®-S can be left exposed for up to 6 months during the construction phase, subject to the following qualifications: the boards must not be left in standing or pooling water or be subjected to any water run-off from roof or slab structures above (protection can be provided by temporary waterproofing measures) and all cut edges should be sealed using FSi Promat Pyrolastic® Silicone, a fire resistant silicone, prior to installation to help prevent any long-term moisture ingress. This is particularly important when considering structural protection to perimeter/edge beams.
Finishes	Decorative. Guidance for specification option: Decorative finishes should be applied in accordance with Promat TDS 056 (https://www.promat.com/en-gb/construction/documentation/) and Appendix Section 7 of the Promat Passive Fire Protection Handbook (https://www.promat.com/en-gb/construction/tools-services/fire-protection-handbook/). Non-decorative. Guidance for specification option: Boards can be left untreated or painted.
Sealant	FSi Promat Pyrocoustic® Fire Resistant Sealant. Guidance for specification option: All boards abutting surrounding structure may be sealed using FSi Promat Pyrocoustic® Fire Resistant Sealant - not required for fire resistance.
