10 misconceptions about aluminium cladding

Today, it is impossible to imagine modern architecture without aluminium cladding. Architects, contractors and private individuals alike are increasingly opting for this durable cladding for new buildings and renovations. Yet many misconceptions still exist. From “it rusts” to “it's too expensive”: in this article, we set out the 10 most common misconceptions about aluminium cladding right.

Misconception 1: Aluminium cladding rusts quickly

Many people think that aluminium will rust just like steel. This is not true. Steel rusts and therefore loses its strength unless properly protected with paint or zinc. Aluminium oxidises do, but this just forms a hard protective layer that stops further deterioration. So the material remains strong and beautiful even after decades.

Misconception 2: Aluminium cladding requires a lot of maintenance

Anyone who has ever had wooden cladding knows that regular painting and oiling is necessary to maintain its appearance. With aluminium, this is a thing of the past. The maintenance of aluminium facade cladding is limited to occasional rinsing with water or a deep cleaner. There are no coatings to renew, and no moss or mould growth occurs as with wood.

Misconception 3: Aluminium is too light and therefore not sturdy

The low weight of aluminium makes some people think it is less strong. In reality, aluminium has an excellent weight-to-strength ratio. Stone strips are sturdy but very heavy and require a load-bearing surface. Composite is lighter, but often more susceptible to colour fading and cracking under stress. Aluminium combines lightness with robustness and is always supported by a solid support structure.

Misconception 4: Aluminium facades are a fire hazard

Many people associate cladding with fire risk, especially with wood or certain plastics that can spread fire. Aluminium, on the other hand, is fireproof and non-combustible: it does not catch fire and does not contribute to fire spread. In the right system design, aluminium cladding effortlessly meets the strictest fire safety standards.

Misconception 5: Aluminium cladding is bad for the environment

Aluminium takes energy to produce, but it is 100% recyclable without loss of quality. More than 75% of the aluminium ever produced is still in use today. This makes it one of the most sustainable facade cladding-options.

Misconception 6: Aluminium cladding discolours quickly

Wood ages the facade and plastic loses its colour, but aluminium becomes powder coated, which ensures long-lasting colour retention. Even popular dark shades such as black aluminium cladding retain their deep colour and matt look without fading or dulling.

Misconception 7: Aluminium façade panels dent easily

Aluminium façade panels are sturdy and are mounted in a stable system. This makes them resistant to normal loads, such as wind pressure or a tap during maintenance. In practice alu facade panels as robust as other facade materials, but lighter and more durable.

Misconception 8: Aluminium expands with heat and deforms

Many materials expand under the influence of heat. Wood may warp or crack as a result. Plastic and composite are even more sensitive and can permanently deform or crack with temperature changes. Aluminium cladding, on the other hand, is dimensionally stable. Thermal expansion is minimal and is also accommodated in the facade system. Horizontal or vertical aluminium facade panels, the facade remains sleek and stable - year after year.

Misconception 9: Aluminium cladding is only for new buildings

Aluminium is not only suitable for sleek new construction projects, but also perfect for renovations. Thanks to its light weight, it can be easily installed on existing walls without the need for heavy interventions. This makes it particularly interesting in facade renovations: installation is fast and efficient, which reduces the cost of facade renovation per m² Moreover, it immediately gives the house a modern, timeless look. Aluminium cladding transforms an outdated exterior wall into a contemporary façade with minimal impact on the existing structure.

Misconception 10: Aluminium cladding only lasts a few decades

In reality, aluminium easily lasts 50 years or more. The price of aluminium facade cladding per m2 pays off in longevity, appearance and minimal maintenance. For those who opt for a modern facade cladding, aluminium is a forward-looking investment.

The truth behind aluminium cladding

Many misconceptions about aluminium cladding are based on outdated information. In reality, it is a durable, low-maintenance and stylish solution that proves itself in both new construction and renovation.
