What is Non-Combustible Cladding?
Non-combustible cladding is a façade system made from materials that do not contribute to fire development or spread under standardised test conditions.
These materials resist ignition and have little to no heat release when exposed to fire, making them a crucial selection for high-risk building zones.
The primary goal of non-combustible cladding is to enhance life safety by slowing fire progression and preserving structural integrity. As part of a rainscreen or ventilated façade system, it acts as a protective barrier between external conditions and the building’s core.
Common applications include large-scale residential towers, public transport infrastructure and commercial façades. Its growing popularity is driven by regulatory pressure and heightened safety expectations following major fire incidents.
Cladding is more than just decoration—it plays a structural and performance-based role, especially in fire-prone environments. Understanding material certification is the first step in ensuring passive fire protection compliance.
Why Fire Safety is Critical in Modern Façade Design
In façade engineering, fire safety drives critical design decisions from planning to installation. Due to increasingly complex urban developments, materials must now meet stringent fire performance metrics without compromising buildability or appearance.
Failures in façade fire performance can lead to catastrophic loss of life and asset damage. The Grenfell Tower fire in London catalysed sweeping reforms that now shape how fire-rated materials are selected and deployed across the UK.
Designers and developers need façade systems that not only meet compliance but enhance occupant assurance across building lifespans. This includes everything from insulation compatibility to bracket fixings and cavity fire barriers.
Cladding systems form layered defences against flame spread, heat transfer, and smoke generation. The correct use of non-combustible systems reduces response times and allows occupants critical minutes to evacuate safely.
Definition and Classification of Non-Combustible Cladding
EN13501-1 Explained: What “Non-Combustible” Really Means
The EN13501-1 standard sets fire classification requirements for construction materials across the European Union and United Kingdom. Materials are assessed for combustibility, smoke production and flaming droplets using full-scale fire tests.
Non-combustible ratings fall under Class A1 (no contribution to fire) and A2-s1,d0 (minimal contribution with limited smoke and droplets). These ratings confirm that the product has undergone disciplined laboratory testing under simulated fire conditions.
Key Fire-Rating Categories: A1 vs A2-s1,d0
Class A1 materials are considered truly non-combustible and release negligible energy during a fire. They produce no significant smoke or burning droplets, making them suitable for all building types, including high-rises.
Class A2-s1,d0 is the next best category, indicating very limited combustibility with controlled smoke emissions (s1) and negligible flaming droplet production (d0). This is common in composite panels that include cementitious backers.
Examples of Certified Non-Combustible Cladding Materials
Typical A1-rated cladding materials include ceramic-coated glass, fibre cement, and metal panels without organic coatings. DynaPanel Glass is a leading example with A1 certification and excellent design adaptability via RAL customisation.
Natural stone composites like DynaPanel Stone, with a Class A2-s1,d0 rating, offer the tactile beauty of granite or limestone while maintaining exceptional fire resistance—a preferred option for those seeking elegance with performance.
Building Regulations and Standards
Complying with UK Fire Safety Legislation
UK building regulations require non-combustible cladding for residential buildings over 11 metres, hospitals, care homes, and educational institutions. Approved Document B forms the basis for compliance, especially concerning external wall systems.
Building Control Authorities also demand a clear fire risk assessment and complete documentation on façade materials and fixings prior to construction sign-off.
Projects That Mandate Non-Combustible Cladding
Key environments where non-combustible façades are mandatory include NHS buildings, airports, underground stations, and residential towers. Projects serving vulnerable populations require systems that limit both fire and smoke spread.
Bomb blast-tested cladding, such as that certified under ASIAD and SIDOS, is regularly deployed in public and transport infrastructure to merge fire protection with resilience against explosive forces.
A Global Perspective: International Regulatory Comparisons
Globally, countries such as Australia, Germany, and the United States apply their own fire classification systems—such as AS 1530.1, DIN 4102, and ASTM E84—which vary in testing methodology and thresholds.
While these differ from EN13501-1, they all share the common aim of minimising fire spread in critical infrastructure. Dynamic Cladding ensures its systems are testable and adaptable to meet multi-jurisdictional requirements.
Most industrial nations now require at least A2-s1,d0 for high-risk applications. This reinforces the need to work with certified manufacturers like Dynamic Cladding, who adhere to international testing protocols and third-party quality verification.
Benefits and Value of Non-Combustible Cladding
Elevated Fire Protection and Peace of Mind
Choosing non-combustible materials ensures alignment with stringent fire codes while significantly improving building resilience. It reduces liability risks and supports safer evacuation strategies during an incident.
Developers and contractors benefit from reduced insurance premiums and enhanced reputational protection, especially when operating in high-density urban zones.
Longevity and Structural Integrity
Non-combustible panels such as DynaPanel Glass and DynaPanel Stone maintain their shape, colour, and cohesion under prolonged exposure to heat or UV degradation. This adds durability to both external and internal applications.
They remain unaffected by rot, mould, or warping—problems commonly associated with organic façade systems.
Low Maintenance with High Return on Investment
Fire-rated cladding often requires less frequent maintenance due to its resistance to thermal deformation and pollution staining. Over time, this translates into lower lifecycle costs per square metre installed.

Frequently Asked Questions
Non-Combustible vs. Fire-Resistant: What’s the Difference?
Fire-resistant materials can delay the effects of heat and fire for a limited duration but may still combust under certain conditions. Non-combustible materials, in contrast, do not contribute to fire at all, making them suitable for stricter applications.
Are Metal Cladding Systems Automatically Safe?
No. While raw aluminium or steel panels may be naturally fire-resistant, composite metal panels can include polymer cores which significantly alter fire behaviour. Always request certified A1 or A2-s1,d0 panels specifically.
Which Buildings Legally Require Non-Combustible Cladding?
All buildings over 11 metres in height, including flats, offices, hospitals, and large public venues must use non-combustible cladding according to UK law. Retrofit projects must comply upon major works or recladding.
How Can I Assess the Compliance of My Existing Façade?
Commission a façade report from a chartered fire engineer or façade consultant. Material samples should be tested against EN13501-1 standards, and installation methods must be matched to certification criteria.
Is metal cladding non-combustible?
It depends on the type of metal and how it is used. Solid metal panels such as aluminium, steel, and zinc are generally non-combustible and can meet classifications such as A1 or A2-s1,d0 under EN13501-1. However, the presence of coatings, insulation layers, or composite backing can alter the fire performance. Only tested, certified metal systems should be specified for fire-critical applications.
Is PVC cladding combustible?
Yes, PVC (polyvinyl chloride) cladding is combustible. It is a plastic material that can ignite and produce toxic smoke when exposed to high heat or open flame. PVC cladding does not meet non-combustible classification standards such as A1 or A2 and is not recommended for use on high-rise or high-risk buildings where fire safety is a priority.
Is aluminium cladding non-combustible?
Solid aluminium itself is non-combustible and can achieve an A1 fire rating. However, many aluminium cladding products on the market are aluminium composite panels (ACPs), which include a plastic or polymer core and sometimes adhesive bonding materials that can be combustible. To ensure safety, use only solid aluminium panels or ACPs with non-combustible cores and adhesives tested to EN13501-1 standards.
Is composite cladding non-combustible?
Most composite cladding materials are not classified as non-combustible, as they often contain polymer or resin-based cores that are flammable. While some high-performance composite panels may offer improved fire resistance, they must be specifically tested and certified to A1 or A2-s1,d0 standards to be considered non-combustible under regulations.
Debunking Cladding Misconceptions
Understanding the Limits of Fire Resistance in Façade Design
Not all so-called “fire-safe” materials behave equivalently under stress. Fire resistance ratings are time-limited, whereas non-combustibility is permanent. Misinterpreting these terms can lead to substandard installation choices.
The Truth Behind “Non-Combustible” Claims: What Really Matters
Several products falsely market themselves as non-combustible without third-party validation. Genuine A1 or A2 materials should always carry test reports, CE marking, and manufacturer verification aligned with UK standards.
