Fiber Cement Board
The all-rounder substrate.
Fiber Cement Board is the workhorse substrate of the modern dry-construction envelope: a high-density panel of Portland cement, fine silica and cellulose fibre, pressure-formed and autoclave-cured into a dimensionally stable sheet that neither burns, rots nor feeds termites. Supplied in 6, 8 and 12 mm thicknesses on the standard 1220 × 2440 mm format, it moves seamlessly between internal partitions, false ceilings, ventilated façade cladding and tile-backer or flooring underlay — one board, specified four ways.

Unlike gypsum, fibre-cement holds its integrity through wetting and drying cycles, making it the default choice for wet areas, semi-exposed soffits and rain-screen build-ups where moisture and impact are facts of life. It is non-combustible to EN 13501-1 (typically classified A2-s1,d0) and carries an ASTM E84 Class A surface-burning rating, so it contributes nothing to fire load or smoke development in the assembly.
We supply Fiber Cement Board to EN 12467, ASTM C1186 and ISO 8336, CE-marked and produced under an ISO 9001 quality system, with full technical and test documentation, to projects across Europe, North America and beyond.

▸Partitions & drywall
Forms robust, impact- and moisture-resistant internal walls in dry and wet rooms where plasterboard would fail.
▸False ceilings
Provides a non-combustible, sag-free ceiling lining for corridors, soffits and service voids requiring a fire-rated plane.
▸External cladding
Acts as the weatherboard or rain-screen panel in ventilated façades, accepting render, paint or decorative coatings.
▸Flooring underlay
Delivers a stable, water-tolerant base for tile, vinyl and resilient finishes over timber or steel joists.
▸Tile backer
Replaces gypsum backing behind ceramics in bathrooms, kitchens and wet zones with a dimensionally stable, moisture-proof substrate.
▸Eaves & soffit linings
Lines semi-exposed external soffits and fascias where durability against weather and rot is essential.
▸Fire rated
Non-combustible to EN 13501-1 (A2-s1,d0) and ASTM E84 Class A — adds no fire load and limits smoke development.
▸Moisture resistant
Holds dimensional integrity through repeated wetting and drying, with no swelling, delamination or loss of strength.
▸Termite & rot proof
Mineral cement composition offers no food source for termites, insects, fungus or mould.
▸High impact strength
Dense, fibre-reinforced matrix resists knocks, abrasion and point loads far better than gypsum board.
▸Dimensionally stable
Low moisture movement keeps joints tight and finishes crack-free across temperature and humidity swings.
▸Workable on site
Scores and snaps or cuts with standard fibre-cement tooling and fixes by screw or nail without specialist plant.
EN 12467
Fibre-cement flat sheets — product specification, strength categories (Class 4) and durability test methods.
EN 13501-1
Reaction-to-fire classification; fibre-cement boards typically achieve A2-s1,d0 (non-combustible, minimal smoke, no flaming droplets).
ASTM C1186
Standard specification for flat non-asbestos fibre-cement sheets, grading physical and mechanical performance for North American projects.
ISO 8336
International product standard for fibre-cement flat sheets — classification, dimensional and mechanical requirements.
CE marking / ISO 9001
CE conformity to the harmonised standard plus production under a certified ISO 9001 quality-management system.
- ▸Cut by score-and-snap for straight lines, or with a dust-extracted diamond/fibre-cement blade; always wear FFP-rated dust protection.
- ▸Fix to timber or light-gauge steel framing at maximum 600 mm centres with corrosion-resistant fibre-cement screws or hot-dip galvanised nails.
- ▸Keep fasteners 12–15 mm from board edges and 50 mm from corners; leave a 3–5 mm control gap between sheets for movement.
- ▸For external cladding, install over a ventilated cavity with a breather membrane and flexible jointing to shed water.
- ▸Acclimatise boards flat and dry on site before fixing; store off the ground under cover, fully supported and protected from rain.
- ▸Finish joints with cement-based jointing compound and fibreglass tape; prime cut edges before applying paint or render.

Fiber Cement Board
questions.
Yes. It is classified A2-s1,d0 to EN 13501-1 (non-combustible, very low smoke, no flaming droplets) and achieves a Class A surface-burning rating to ASTM E84. It contributes no fuel to a fire and is suitable for fire-rated wall and ceiling assemblies.
It can. Fibre-cement is moisture-proof and freeze-thaw stable, so it suits external cladding, ventilated façades, eaves soffits, bathrooms and tile-backer applications without swelling or rotting. For façades, install over a drained, ventilated cavity.
As a guide: 6 mm for ceilings, soffits and tile backer; 8 mm for general partitions, drywall and cladding; and 12 mm for flooring underlay and high-impact walls. Our technical team can confirm against your framing centres and loads.
No. It is 100% asbestos-free, manufactured from Portland cement, silica and cellulose fibre, and complies with the non-asbestos fibre-cement standards EN 12467, ASTM C1186 and ISO 8336.
Straight cuts are made by score-and-snap or with a dust-extracted diamond blade; boards fix to timber or steel framing with corrosion-resistant screws or galvanised nails at up to 600 mm centres. Joints are taped and filled with cement-based compound.
Each order ships with a Technical Data Sheet, EN 12467 and ASTM C1186 test reports, a CE Declaration of Performance and a product warranty. Production is carried out under an ISO 9001 quality system, with full export documentation provided.
Standard 6, 8 and 12 mm boards are stocked for prompt despatch; recessed-edge and bespoke sizes are made to programme. We supply across Europe, North America and beyond, palletised and edge-protected, with complete shipping documentation.
