Composite facade cladding is a lightweight, flat-surfaced exterior wall system made by sandwiching a core layer between two thin metal sheets, usually aluminium. Mechanically fixed to a building's facade, these panels are a common choice both for new construction and for re-cladding (as a curtain wall) an existing building, offering a smooth, modern appearance.
How a composite panel is built
A composite panel has three layers: a thin metal sheet on top, one on the bottom, and a core layer bonding the two together. The metal sheets are usually aluminium, finished with electrostatic powder coating or a similar surface treatment for colour. The core type affects the panel's weight, rigidity and fire behaviour, so it should be chosen together with a qualified engineer based on the building's type and height. Fire safety and core types deserve a dedicated look, which we cover in more detail in a separate article; always check local regulations on this point.
Standout advantages
- Lightweight: far lighter than solid metal sheeting, so it adds minimal load to the supporting structure.
- Flat, smooth finish: creates wide, seamless surfaces with no visible joints or welds.
- Wide colour and texture choice: RAL colours, metallic tones or different surface textures adapt to almost any architectural design.
- Fast installation: panels cut to standard sizes shorten the overall installation timeline.
- Low maintenance: with the right surface finish, it holds up to the elements for a long time without heavy upkeep.
- Facade refresh: applied as a curtain wall over an existing facade, it can transform a building's exterior appearance.
Where it is used
Composite facade cladding is used on commercial buildings, office blocks, shopping centres, industrial facilities and residential projects as an exterior wall finish. It also suits interior uses such as suspended ceilings, signage backing or decorative wall cladding. It is particularly popular on large, flat industrial buildings, where it offers both an aesthetic upgrade and fast installation. See a real example on our composite facade cladding for an industrial building project page.
How the installation system works
Composite panels are not fixed directly to the load-bearing wall; instead they attach to a sub-frame (a grid of rails or profiles) that leaves an air gap between the wall and the panel. This gap helps moisture drain and supports insulation performance. Panels are mounted to the sub-frame with hidden or visible fasteners, and expansion joints are left between panel edges to allow for thermal movement. If joint width is not planned correctly, the panel can warp or bow over time. Facade measurements and sub-frame design are finalised during survey and project design.
Performance in coastal, hot-climate conditions
In a coastal area such as Famagusta, how well a facade material handles sun and salt air is a key selection factor. Composite panels with a quality electrostatic powder coating on the aluminium surface resist fading and corrosion over a long period. The air gap behind the panel also helps dissipate heat that builds up on the facade surface during the long, sunny summer. In winter, the right joint detailing and drainage channels stop moisture from accumulating behind the panel during the rainy season.
Maintenance and cleaning
Composite facade panels need little beyond regular cleaning with water and a mild detergent. Avoid abrasive chemicals and stiff brushes, which can scratch the surface finish or leave dull patches. Periodically checking joint sealant and fasteners helps keep the panel performing well over the long term. For a regular maintenance plan, see our service and maintenance page.
Colour and finish options
Composite panel colours are typically chosen from the RAL palette, with matte, gloss, metallic or wood-effect finishes also available. This broad range makes it easier to achieve the exact visual effect a design calls for. When choosing colour and texture, it is worth considering how the building relates to its surroundings and the wider architectural language of the area.
Thermal and acoustic contribution
The air gap left behind a composite panel, together with any additional insulation layer, forms a second protective shell over the building's exterior wall and can help reduce heat transfer. This effect depends less on the panel itself and more on the overall facade detailing: air gap, insulation and joint sealing working together. A similar principle applies to acoustics, where the gap behind the panel can help dampen some exterior noise, though exact performance depends on project-specific detailing.
Using it to re-clad an existing building
One of the most practical uses of composite panelling is refreshing a facade on a building that looks dated or has deteriorated. Without demolishing the existing wall, a sub-frame is installed and composite panels mounted over it, giving the building an entirely new exterior appearance. This approach is especially practical for commercial and industrial buildings that want a facade upgrade without disrupting daily operations. Before installation, the existing wall's load capacity and flatness should be checked on site.
Sub-frame material choice
Beyond the visible panel surface, the material of the sub-frame it is fixed to also affects how long a facade performs well. Sub-frames are typically made from aluminium profile or galvanised steel; which one is used depends on facade height, wind load and budget, and is settled during project design. In a coastal, salt-laden climate, giving the sub-frame material its own surface protection is a detail that is easy to overlook but structurally important.
Frequently asked questions
What material is composite facade cladding made of?
It is typically made of two thin aluminium sheets sandwiching a core layer. The aluminium surfaces are coated with electrostatic powder coating or a similar finish to add colour and protect against the elements.
How long does composite panel installation take?
Timing depends on facade area, panel size and the complexity of the sub-frame system. There is no fixed duration; it is best assessed after an on-site survey specific to your project.
Can composite panels be applied to an existing building's facade?
Yes, composite panelling can be installed as a curtain wall over an existing facade by fixing a sub-frame system to the wall. This method is a common way to refresh the exterior of older buildings.
Does composite facade cladding need maintenance?
Yes, but maintenance needs are low. Regular water cleaning and periodic checks of joints and fasteners are usually sufficient.
What colours are available for composite panels?
Nearly any colour in the RAL palette is available, along with metallic and wood-effect finishes. Colour and texture are chosen based on the architectural design and the building's surroundings.
With the right core type, installation detailing and surface finish, composite facade cladding delivers a long-lasting, low-maintenance exterior solution. To discuss the right system for your project, reach out through our contact page.
