Vermiculux®-S

An A1 non-combustible calcium silicate board which provides 30–240 minutes' fire protection to structural steel. The product is suitable for column and beam encasements and is moisture resistant.

Offers a permanent dimensional stability, so in the event of a fire it reduces the speed at which the steelwork will heat up, allowing it to maintain its loadbearing capacity for longer.

Features and benefits:

• Fully traceable processes and products.

• Moisture resistant.

• Mould resistant.

• Flexible.

• Durable.

• Easy to decorate.

• Comprehensively strong.

• Boards can be painted with emulsion or water-based paints.

Exposed surface area-to-volume (A/V) ratio for column and beam encasement:

Refer to the Promat Passive Fire Protection Handbook (or the ASFP Yellow Book) and consult the manufacturer for further details.

Applications:

• Designed to provide fire protection for buildings storing high value items or assets including museums, data centres and bonded warehouses.

• Can be used during early stages of construction, when a building is not weathertight.

• Where additional fire safety measures are required for high risk areas, such as boiler or plant rooms, transport infrastructure and power stations.

Used to provide, one, two, three or four sides encasements to:

• Universal columns and beams ('I' or 'H' sections), joists and rolled steel joists (RSJs).

• Structural hollow sections.

• Bracing.

• Lattice beams.

• Partially exposed members.

• Perimeter beams.

• Beams supporting composite floors with profiled metal decking.

• Wind posts.
