Cladding panels are one of the most important decisions you will make during any building project. Whether you are working on a new commercial development, refurbishing a residential block or upgrading an agricultural building, the panels you specify will determine how your building looks, how it weathers over time, and whether it meets current fire safety regulations.
The main types of cladding panels used in the UK are metal, composite, fibre cement, timber, brick slip, and high pressure laminate. Each material offers different fire ratings, durability, and aesthetics. Aluminium and fibre cement provide the highest fire performance, while timber and composite suit smaller residential projects under 11 metres.
With dozens of panel types available and evolving regulatory requirements to navigate, choosing the right cladding system can feel complicated. This guide cuts through the noise and explains everything you need to know about cladding panels, from material types and performance characteristics to fire classifications and cost considerations.
What Are Cladding Panels?
Cladding panels are prefabricated sheets or boards fixed to the exterior walls of a building to protect the structure from weather, improve thermal performance and enhance visual appeal. Unlike render or brickwork, cladding panels are installed as discrete units, typically fixed to a supporting framework or battens rather than applied directly to the substrate.
Most modern cladding systems use a rainscreen cladding approach, where a ventilated cavity sits between the panels and the building structure. This cavity allows moisture to drain away and air to circulate, preventing the damp related problems that shorten the lifespan of external walls.
Cladding panels come in a wide range of materials, including metal, composite, fibre cement, timber, brick slips and high pressure laminate. The right choice depends on the building type, height, fire performance requirements, budget and desired aesthetic.
Types of Cladding Panels
Metal Cladding Panels
Metal cladding panels, typically made from aluminium or steel, are among the most widely specified options for both commercial and industrial projects. Aluminium offers excellent corrosion resistance and a high strength to weight ratio, making it ideal for larger facades where structural loading is a concern.
Aluminium rainscreen panels like the VulcaLap plank system achieve A2 fire ratings and are available in a range of profiles including tongue and groove, shiplap and cassette formats. Powder coated finishes or anodised surfaces provide decades of weather protection with minimal maintenance.
Steel cladding panels are common on agricultural buildings, warehouses and industrial sheds. Galvanised or plastisol coated steel sheets offer robust protection at a competitive price point, though they lack the design flexibility of aluminium for architectural projects.
Composite Cladding Panels
Composite panels combine two or more materials to achieve specific performance characteristics. Aluminium composite material (ACM) panels consist of two aluminium sheets bonded to a core material. Following the Grenfell Tower tragedy, ACM with an unmodified polyethylene core is now banned on residential buildings over 11 metres. Fire retardant mineral core ACM panels remain compliant and widely used on commercial facades.
Wood plastic composite (WPC) panels blend recycled wood fibres with high density polyethylene to create durable, low maintenance boards. These are popular on residential projects under 11 metres where combustible materials are still permitted. WPC panels typically achieve Euroclass B or C fire ratings depending on their formulation.
Fibre Cement Cladding Panels
Fibre cement panels are manufactured from Portland cement, cellulose fibres and sand. They offer excellent fire performance, achieving A1 or A2 classifications, making them suitable for taller buildings and projects with strict fire safety requirements.
Fibre cement is non combustible, dimensionally stable and highly resistant to moisture. Panels can be supplied in smooth, textured or woodgrain finishes and accept a wide range of coatings. The material is heavier than aluminium or composite options, so adequate structural support is essential during specification.
Timber Cladding Panels
Timber remains a popular choice for residential projects, garden rooms and extensions where natural aesthetics are a priority. Cedar, larch and thermally modified timber species offer good durability in the UK climate when properly installed and maintained.
Timber cladding achieves Euroclass D fire rating in its natural state. Fire retardant treatments can improve this to Class B, but timber cannot achieve A1 or A2 classifications because wood is inherently combustible. This restricts its use on residential buildings over 18 metres and certain institutional buildings regardless of height.
Brick Slip Cladding Panels
Brick slip panels consist of thin brick tiles bonded to a backing board, creating the appearance of traditional masonry at a fraction of the weight and cost. They are particularly useful on refurbishment projects where matching existing brickwork is important, or where planning restrictions favour traditional materials.
Brick slips achieve strong fire ratings when fixed to appropriate backing boards and are highly durable once installed. However, the material is more expensive than many alternatives and requires skilled installation to achieve neat pointing and alignment.
High Pressure Laminate (HPL) Panels
HPL panels are created by pressing layers of kraft paper impregnated with thermosetting resin under high heat and pressure. They offer outstanding design flexibility with a vast range of colours, patterns and surface finishes available.
HPL is lightweight, weather resistant and can achieve good fire ratings when specified correctly. The material is common on feature facades, accent panels and mixed use developments where visual impact is a key design driver.
How to Choose the Right Cladding Panels
Selecting cladding panels involves balancing several factors. The following considerations should guide your decision.
Building Height and Fire Requirements
Building height is the single most important factor in determining which cladding panels are compliant. Under current UK Building Regulations, residential buildings with a storey at 11 metres or above require external wall materials to achieve a minimum Euroclass rating of A2-s1,d0. This effectively mandates non combustible materials such as aluminium, fibre cement or mineral core ACM.
For buildings below 11 metres, combustible materials including timber and standard WPC composite remain permissible, provided they meet the required fire rating for their specific location and proximity to boundaries.
Commercial buildings have different requirements. While high rise commercial structures may require A1 or A2 rated systems, smaller commercial buildings and agricultural sheds can often specify combustible materials with fewer restrictions.
Exposure and Weather Resistance
Coastal locations demand materials with high corrosion resistance. Aluminium and fibre cement perform well in salt laden environments, while untreated steel and certain composite panels may corrode prematurely.
Heavily exposed upland sites with high rainfall and wind loading favour robust, rigid panels with concealed fixing systems. Lightweight materials may flutter or suffer wind uplift damage if not properly specified for the site conditions.
Shaded elevations in damp climates are prone to algae and moss growth. Smooth faced panels with antimicrobial coatings or naturally resistant materials like aluminium reduce maintenance demands in these situations.
Aesthetic and Design Intent
Cladding panels are highly visible and define the character of a building. Natural timber tones suit rural settings and residential projects where warmth and texture are desired. Contemporary grey and anthracite finishes are popular on modern commercial developments.
Metallic and anodised aluminium panels create crisp, industrial aesthetics suited to office blocks and leisure facilities. Brick slip panels allow new builds to blend seamlessly with traditional streetscapes.
Consider how the panel profile affects appearance. Horizontal planks create visual width, while vertical panels emphasise height. Cassette systems with concealed fixings offer clean, uninterrupted facades.
Durability and Maintenance
Maintenance requirements vary significantly between materials. Aluminium and fibre cement panels need little more than periodic washing to maintain their appearance. Powder coated metal finishes typically carry 25 year guarantees against fading and chalking.
Timber cladding requires regular inspection and recoating every few years to prevent weathering and surface degradation. WPC composite panels sit between these extremes, offering better durability than timber but requiring more care than metal or fibre cement.
Cost Considerations
Material costs for cladding panels vary widely. As a rough guide for the UK market in 2026, expect the following per square metre costs for materials alone:
Steel cladding sheets typically cost between £20 and £45 per square metre. Aluminium rainscreen panels range from £60 to £150 per square metre depending on profile, finish and fire rating. Fibre cement boards generally sit between £50 and £100 per square metre. Timber cladding costs £40 to £100 per square metre for the boards, though premium hardwoods exceed this. Composite panels range from £45 to £120 per square metre.
These figures exclude subframe, fixings, cavity barriers, trims and installation labour. Full installed systems typically add 60% to 100% to the material cost depending on access, complexity and regional labour rates.
Installation and Compliance
Cladding panel installation requires careful attention to ventilation, drainage and fire stopping. The cavity behind the panels must remain clear to allow airflow and moisture escape. Cavity barriers and fire stops must be positioned in line with Approved Document B guidance to prevent flame spread within the wall system.
Panel fixings should be appropriate for the material and exposure. Stainless steel fixings prevent corrosion staining on light coloured panels. Concealed clip systems maintain clean sightlines and allow thermal movement without visible fasteners.
Expansion gaps are essential with all materials. Panels expand and contract with temperature changes, and failing to accommodate this movement leads to buckling, cracking or fastener failure. Always follow manufacturer guidance on spacing and fixing tolerances.
Planning and Building Control
Most cladding projects on existing buildings fall under permitted development and do not require planning permission, provided the panels are reasonably similar in appearance to the existing finish. However, properties in conservation areas, national parks and areas of outstanding natural beauty almost always require formal planning consent.
Even where planning permission is not needed, Building Regulations approval is required for any work affecting the external walls of a building. Building control will scrutinise fire performance, structural adequacy, thermal performance and ventilation provision. Submit detailed specifications and test certificates early in the process to avoid costly delays.
For guidance on fire performance assessments and compliance, the RICS guidance on external wall systems provides valuable technical background on the assessment process.
Frequently Asked Questions
What is the difference between cladding panels and cladding boards?
Cladding panels are usually larger sheets, while cladding boards are narrower planks. Both are used to protect and finish external walls.
Can cladding panels be installed on any building?
Most buildings can support cladding panels, but older or weaker structures may need extra support first.
How long do cladding panels last?
Cladding panels can last 20 to 50 years, depending on the material. Aluminium and fibre cement usually last longer than timber or WPC.
Do cladding panels improve insulation?
Cladding panels do not provide much insulation on their own, but they can improve performance when installed with insulation behind them.
What are the fire safety requirements for cladding panels?
Fire safety rules depend on the building type and height. For buildings over 11 metres, cladding materials usually need an A2-s1,d0 rating.
Can I install cladding panels myself?
Small projects may be suitable for DIY, but professional installation is recommended for most buildings.
Are cladding panels recyclable?
Some cladding panels are recyclable, especially aluminium and steel. Recyclability depends on the material used.
