The Future of Fire-Safe Outdoor Spaces: Why Choose Wallbarn’s C-Deck Cement Fibre Decking?

As the demand for safe, durable and compliant outdoor surfaces continues to rise, particularly in urban construction and high-rise developments, the materials used for decking have come under increasing scrutiny. Traditional timber and composite solutions, while visually appealing, often fall short when tested against modern fire safety regulations. Wallbarn’s C-Deck Cement Fibre Decking offers a highly effective alternative that not only meets the most stringent safety standards but also delivers on aesthetics, performance and longevity.

Ideal for terraces, balconies, podiums, roof gardens and external communal areas, C-Deck is a robust and contemporary decking system specifically engineered for high-performance environments. Below, we explore the many benefits of this advanced cement fibre solution and why it’s becoming a preferred specification choice for developers, architects and contractors.

Class A Fire-Rated for Full Compliance

One of the most significant advantages of C-Deck is its Class A2-s1, d0 fire rating in accordance with EN13501-1. This classification means the material is non-combustible, emits little to no smoke when exposed to fire, and does not produce flaming droplets. In light of increasingly strict fire regulations in the UK and across Europe, especially for buildings above 11 metres, this makes C-Deck a reliable and compliant choice.

Unlike timber, composite, or plastic-based decking systems, C-Deck contains no organic material, plastic or flammable content. It provides peace of mind for those designing or managing projects that must adhere to current safety legislation, including residential high-rises, hotels, and mixed-use developments.

Durable and Weather-Resistant

C-Deck is designed to endure extreme environmental conditions without compromising its appearance or structural integrity. Manufactured from fibre cement, this decking is:

• Resistant to moisture and humidity
• Unaffected by frost and ice
• Impervious to UV degradation
• Highly resistant to biological growth such as mould, algae and fungi

These characteristics make it especially well-suited for outdoor applications where exposure to the elements is constant. Over time, traditional timber may warp, swell or splinter, while composites can fade or become brittle. C-Deck, however, remains stable and consistent throughout seasonal changes and heavy use.

Low Maintenance Requirements

Another key benefit is its low maintenance profile. Because of its resistance to water absorption, staining and biological growth, C-Deck does not require sealing, staining or chemical treatments. Cleaning is straightforward—often limited to the occasional wash with water or a mild detergent.

For commercial or shared spaces, this dramatically reduces ongoing maintenance costs and eliminates the labour associated with regular upkeep. It also removes the need for potentially harmful coatings or preservatives, supporting a healthier and more sustainable installation.

Modern Aesthetics with Urban Appeal

While safety and durability are vital, visual appeal remains a top priority in outdoor space design. C-Deck delivers a clean, contemporary finish with subtle textures and natural tones that complement modern architectural styles. The planks have a consistent surface and a pleasing, minimalist grain pattern that mimics timber while maintaining the sharp, precise edges characteristic of engineered stone.

This aesthetic versatility allows C-Deck to be specified across a wide variety of projects—from luxury apartments and urban rooftops to public walkways and commercial terraces. It is particularly effective in settings where a professional, modern appearance is required without compromising safety.

Fast, Flexible Installation

C-Deck is part of Wallbarn’s modular, non-combustible decking system and is designed for compatibility with MetalPad EX pedestals and aluminium substructure joists. These components work in unison to create a secure, level platform that can accommodate a variety of layouts and site conditions.

The installation process is efficient and tidy, with no need for adhesives or mechanical fixings directly into the cement fibre boards. This approach reduces on-site disruption and allows for easy removal and replacement of planks in the future, whether for maintenance access or aesthetic updates.

Adjustable pedestals make it possible to correct for uneven surfaces, integrate drainage slopes, or run services beneath the deck—all without compromising the finished appearance.

Ideal for High-Rise and Public Spaces

Given its fire classification, durability and non-slip surface profile, C-Deck is ideal for:

• Residential balconies and roof terraces
• Podium decks and garden walkways
• Communal outdoor areas in housing developments
• Hotel courtyards and external dining zones
• School playgrounds and healthcare terraces

The versatility of the system ensures that it can be tailored to suit a wide range of applications, providing confidence for specifiers across residential, commercial and public sector projects.

Environmentally Responsible

C-Deck is a mineral-based product, manufactured with sustainability in mind. Its long lifespan reduces the need for replacement, and its composition avoids the use of plastic, resin or synthetic additives. At the end of its service life, the material can be broken down and recycled, making it a responsible choice for eco-conscious developments.

Furthermore, its lack of chemical preservatives or coatings makes it a safer material for people, pets, and surrounding plant life—especially in rooftop garden settings.
