Why Non-Combustible Decking from Wallbarn is the Smart Choice for Safe and Stylish Outdoor Spaces

In today’s construction landscape, safety, compliance, and long-term performance are more important than ever—especially when it comes to external decks on balconies, podiums, roof terraces, and communal walkways. Following the revision of Building Regulations and growing demand for fire-safe materials, architects, developers and contractors are under pressure to choose systems that offer more than just aesthetic appeal. Wallbarn’s non-combustible decking systems are engineered to meet this challenge, offering a range of fully compliant solutions that do not compromise on design, durability or ease of installation.

Whether you are working on a high-rise residential development, a commercial property or a public space, specifying a Class A-rated decking system is now more than a recommendation—it is often a legal requirement. Wallbarn provides a complete portfolio of non-combustible decking options, all designed to perform in demanding environments.

What Is Non-Combustible Decking?

Non-combustible decking refers to surface materials and supporting substructures that are manufactured without flammable components, and that meet the highest standards for fire resistance. Under EN13501-1, decking systems are tested and rated from Class F (combustible) to Class A1 or A2 (non-combustible). In the UK, for residential buildings above 11 metres, only materials with a minimum fire rating of Class A2-s1, d0 are permitted for use on balconies and external wall systems.

Wallbarn’s range of non-combustible decking products has been developed with this legislation in mind. Each component—from the surface boards to the substructure—is Class A fire-rated and free from plastic or timber content, ensuring full compliance and total peace of mind.

The Wallbarn Non-Combustible Decking Range

Wallbarn offers a carefully curated selection of non-combustible decking products, including:

• Porcelain Decking: Combining elegance with durability, this premium solution replicates the look of natural wood while delivering Class A1-rated fire performance.
• C-Deck Cement Fibre Decking: A contemporary and robust fibre cement board that provides excellent fire resistance, slip performance and low maintenance.
• Aluminium Decking: A sleek, lightweight and fully recyclable solution offering maximum fire safety with an industrial or modern finish.

Each system is fully compatible with Wallbarn’s MetalPad EX pedestal and aluminium joist framework, which are also Class A-rated. This complete system ensures that every layer—from surface to substrate—complies with the latest fire safety standards.

Key Benefits of Wallbarn’s Non-Combustible Decking Systems

1. Class A Fire-Rated Compliance

All decking boards and supporting structures are tested to EN13501-1 and meet or exceed Class A2-s1, d0 requirements. This ensures they are non-combustible, produce little or no smoke, and emit no flaming droplets during fire exposure. This is essential not only for high-rise residential buildings, but also for commercial properties, hospitals, schools and public spaces.

2. Complete System Approach

Wallbarn offers more than just individual decking boards. The company provides a full-system solution, including:

• Fire-rated pedestals
• Aluminium joists and rails
• Fixings and headpieces
• Substructure accessories

This holistic approach guarantees compatibility, simplifies installation, and helps clients meet regulatory obligations with confidence.

3. Minimal Maintenance

Unlike traditional timber or composite products, Wallbarn’s non-combustible decking boards are resistant to moisture, rot, algae, and UV damage. This significantly reduces maintenance requirements, offering a long service life with minimal upkeep. There’s no need for sanding, sealing, painting or chemical treatments—just a simple clean when needed.

4. Superior Durability and Weather Resistance

Wallbarn’s non-combustible systems are designed for long-term performance. Porcelain and cement fibre boards are highly resistant to thermal changes, frost, and water ingress. Aluminium boards offer corrosion resistance and mechanical strength, making them ideal for exposed or marine environments. These materials will not degrade, warp or discolour over time.

5. Design Flexibility and Aesthetic Appeal

While safety and performance are non-negotiable, visual impact remains an important consideration. Wallbarn’s decking solutions provide a variety of finishes and styles to suit any design brief—from the refined timber-look of porcelain and C-Deck, to the crisp, architectural lines of aluminium decking. These finishes can be coordinated with planters, furniture and façade elements to create a cohesive, modern aesthetic.

6. Easy Installation and Accessibility

All non-combustible systems are designed for fast, efficient installation using Wallbarn’s adjustable pedestals and joist rails. The modular setup allows for precision height adjustments, accommodates uneven substrates, and creates a void beneath the surface for drainage or service access. Boards can be removed and replaced individually without dismantling the entire structure.

7. Environmentally Responsible Materials

Wallbarn’s decking products are free from harmful chemicals and are recyclable at the end of their lifecycle. By avoiding plastic and timber, these systems reduce reliance on virgin materials and help to limit environmental impact. This supports sustainability targets and contributes positively to BREEAM or LEED certification goals.

Applications and Use Cases

Wallbarn’s non-combustible decking systems are ideally suited for:

• High-rise apartment balconies and walkways
• Podium decks and rooftop terraces
• Commercial developments with elevated outdoor space
• Hospitality venues such as hotels, bars and restaurants
• Education, healthcare and civic buildings
• Retrofit or recladding projects requiring upgraded fire compliance

These systems offer versatility across sectors and deliver long-term value to developers, contractors and end users alike.
