C-Deck Cement-Fibre Decking: Timber Look, Fire Safety Built-In

The demand for decking that delivers both beauty and safety has never been higher. Developers, architects and homeowners alike are seeking outdoor solutions that look great, perform well, and comply with today’s strict building regulations.

Wallbarn’s C-Deck Cement-Fibre Decking provides exactly that — combining the warm appearance of natural timber with the strength, durability and non-combustibility required for modern construction. Designed for high-rise balconies, rooftop terraces and ground-level applications, it offers all the character of wood without the risk.

The Need for Fire-Safe Decking

In recent years, fire safety regulations have tightened across the UK. Buildings above 18 metres (and, increasingly, lower-rise multi-occupancy structures) must now use non-combustible materials for external surfaces such as decking and cladding.

Traditional timber or composite boards may look attractive but often fail to meet these critical standards. The result is a growing shift towards cement-fibre decking, a new generation of materials engineered to deliver the same aesthetic appeal while achieving a Class A fire rating.

Wallbarn’s C-Deck system is fully compliant with Approved Document B, making it ideal for any project where safety cannot be compromised.

Timber Aesthetics Without Timber Risks

Many property owners still prefer the appearance of natural wood. C-Deck’s beauty lies in its ability to replicate that timeless look while eliminating the issues associated with real timber.

The boards are manufactured using a high-density cement-fibre composition, with surface finishes that emulate wood grain patterns and rich, natural tones. The result is a surface that feels authentic yet requires minimal maintenance.

Unlike timber, C-Deck will not rot, warp or splinter — even after years of exposure to the elements. There is no need for staining, sealing or oiling, allowing you to enjoy the warm, organic look of wood without ongoing upkeep.

Built to Withstand the Elements

Outdoor spaces demand resilience. C-Deck is engineered for maximum weather resistance, performing exceptionally in both residential and commercial environments.

Key performance advantages include:

• Frost and moisture resistance — boards will not absorb water or degrade over time.

• UV stability — colours remain consistent, even after prolonged sun exposure.

• High load-bearing capacity — ideal for high-traffic areas such as communal terraces.

• Slip resistance — providing a safe, stable surface in all conditions.

Because it is impervious to rot and mould, C-Deck offers long-term durability, reducing replacement costs and environmental waste.

Fully Non-Combustible, Fully Compliant

Fire performance is at the core of the C-Deck system. Each board achieves Class A2-s1,d0 fire classification — meaning it is non-combustible and produces minimal smoke or flaming droplets in the event of a fire.

When installed over a compatible Class A substructure, such as Wallbarn’s MetalPad EX adjustable pedestals, specifiers can achieve a fully compliant build-up from base to surface.

This makes C-Deck suitable for use in high-risk applications including:

• Rooftop terraces on apartment buildings

• Balconies on mixed-use developments

• Podium decks and communal courtyards

• Commercial and public access areas

By choosing a fire-safe system, developers protect both their projects and their reputations.

Simple, Fast Installation

C-Deck has been designed for ease of installation. The boards fit securely onto Wallbarn’s adjustable pedestal systems, allowing for precise levelling and quick on-site adjustments.

Because there are no fixings penetrating the waterproof membrane below, the system also helps maintain roof integrity and improves water drainage.

The modular design means individual boards can be lifted or replaced without disturbing the rest of the decking — an advantage particularly valued by maintenance teams.

Together with Wallbarn’s renowned technical support, this ensures a smooth, efficient installation process from start to finish.

Sustainable Choice for Modern Construction

C-Deck’s cement-fibre composition is environmentally responsible, containing no plastics, resins or toxic additives. Its long service life and low maintenance requirements further reduce its environmental footprint.

The boards are also fully recyclable, aligning with sustainable design goals and helping clients meet their ESG and BREEAM commitments.

By choosing C-Deck, specifiers and developers contribute to safer, greener, and longer-lasting outdoor environments.
