Calcium Silicate Board
Fire protection, A1-rated.
Calcium silicate board is a lightweight, asbestos-free building panel manufactured from siliceous and calcareous materials reinforced with cellulose fibres, autoclaved under high pressure to produce a stable, mineral-bonded sheet. Classified Class A1 non-combustible to EN 13501-1, it is the panel of choice where passive fire protection is the governing requirement — steel and concrete encasement, fire-rated partitions, ductwork enclosures and protected ceiling systems.

Unlike standard gypsum-based boards, calcium silicate retains its integrity at elevated temperatures and resists moisture-driven movement, making it equally suited to humid and semi-exposed internal environments. The matrix is free of asbestos and formaldehyde, and the boards are dimensionally stable across a wide service-temperature range. Surfaces accept paint, render, tile and most decorative finishes directly after standard preparation.
Supplied in the standard 1220 x 2440 mm format from 6 mm upwards, with thicker gauges available for higher fire-resistance periods, our calcium silicate boards are delivered with full technical documentation and exported across Europe, North America and beyond to EN, ASTM and ISO requirements.

▸Fire protection
Encasement of structural steel and concrete and construction of fire-rated barriers where a non-combustible substrate is mandated.
▸Ceiling systems
Suspended and fixed ceilings, including fire-rated and membrane ceilings in commercial and public buildings.
▸Duct enclosures
Smoke and ventilation duct casings requiring stability and fire integrity at elevated temperatures.
▸Partitions
Fire-rated and moisture-tolerant internal partition linings in offices, hospitals, transport and industrial interiors.
▸Service shafts & risers
Lining of vertical shafts and risers to maintain compartmentation and protect escape routes.
▸Semi-exposed soffits
Protected external soffits and canopies where humidity resistance and non-combustibility are required.
▸Non-combustible
Class A1 reaction to fire means the board contributes no fuel load and will not spread flame.
▸Lightweight
Lower density than mineral boards of equivalent rating eases handling and reduces structural dead load.
▸Asbestos-free
A safe, modern cellulose-reinforced matrix with no asbestos or formaldehyde content.
▸Dimensionally stable
Minimal moisture movement keeps joints tight and finishes intact in fluctuating conditions.
▸Moisture-tolerant
Resists swelling and degradation in humid and semi-exposed internal environments.
▸Versatile finish
Accepts paint, tile, render and decorative laminates directly after standard surface preparation.

EN 12467
Fibre-cement / mineral-bonded flat sheets — specification, mechanical and physical performance, and test methods.
ASTM C1186
US specification for flat non-asbestos fibre-cement sheets, including density and strength classification.

- ▸Store flat on a level, dry surface with full-length bearers; never stand boards on edge unsupported.
- ▸Cut with a carbide-tipped blade or score-and-snap; work in ventilated areas and use dust extraction or respiratory protection.
- ▸Fix to steel or timber framing with corrosion-resistant screws, observing recommended edge distances and fastener centres.
- ▸Leave a control gap at board joints and perimeters to accommodate movement; reinforce and fill joints per the system detail.
- ▸For fire-rated assemblies, follow the specified layer count, board thickness and joint staggering to achieve the rated EI/REI period.
- ▸Allow boards to acclimatise to ambient conditions before fixing and decorating in heated interiors.

Standard grades and thicknesses are typically held in stock for prompt dispatch, while high-density grades, non-standard thicknesses and cut-to-size orders are produced to order with lead times confirmed at enquiry; representative samples and full-size boards are available for evaluation and specification approval. Every consignment ships with a Technical Data Sheet, EN 13501-1 reaction-to-fire classification and supporting test reports, declaration of asbestos-free composition, CE documentation where applicable and a product warranty, and we export worldwide across Europe, North America and beyond with complete shipping and conformity documentation.
Calcium Silicate Board
questions.
Yes. The boards are reinforced with cellulose fibre and contain no asbestos or formaldehyde; a declaration of composition is supplied with every consignment.
The board itself is Class A1 / A2-s1,d0 non-combustible to EN 13501-1. The fire-resistance period (e.g. EI 60, EI 120) depends on the assembled system, board thickness and layer count.
Yes. Calcium silicate resists moisture-driven swelling and degradation, making it suitable for humid interiors and protected semi-exposed soffits, unlike standard gypsum board.
Thicknesses run from 6 mm to 25 mm. Thinner gauges suit ceilings and linings; thicker gauges are specified for higher fire-resistance periods and structural encasement.
Cut with a carbide-tipped blade or score-and-snap using dust extraction, and fix to steel or timber framing with corrosion-resistant screws at the specified centres.
Yes. The smooth sanded face accepts paint, tile, render and decorative laminates directly after standard joint treatment and surface preparation.
We supply across Europe, North America and beyond, with each shipment accompanied by TDS, fire classification, test reports, CE documentation where applicable and warranty.
