Aluminum cladding was used as early as 1920 for the construction of the Empire State Building. It remained popular until the 1970s. Nowadays, despite its great qualities, aluminum is one of the least popular options due to its cost, which is superior to that of other materials.

The pros of exterior aluminum siding

The lifespan of the material

Aluminum has great inherent qualities. First and foremost, it is both very light and very durable. It has a lifespan of more than forty years and with a little bit of maintenance, it can last much longer than that. It is very resistant to rust and is non-combustible: contrary to many other wall cladding materials, it doesn’t burn and doesn’t melt.


It is waterproof and rot-proof, which means that is doesn’t decay, doesn’t develop mould and has nothing to fear about harmful insects like rodents and termites. This comes from the fact that it doesn’t contain any organic matter. Furthermore, aluminum cladding doesn’t absorb water and is stable when faced with variations in humidity.

The choice of colours and textures available on the market

Aluminum cladding is available in a wide array of finishes. Paint adheres well to this type of surface; therefore, it can be painted in an endless variety of colours. It is also possible to give it an anodized finish. Also: applying cooked enamel or wood grain on the surface can imitate the appearance of other materials and give a more traditional look.

The cons of exterior aluminum siding

The material's price

Aluminum is expensive, both for purchase and for renovations. Since the manufacturing of aluminum requires large amounts of energy and raw materials, this type of exterior cladding is 15 to 20% more expensive than other materials from the same category. 

For all these reasons, it is used almost exclusively for soffits, mouldings or flashings and rarely for exterior wall cladding. This means that other materials such as vinyl products, wood fibre, fibro-cement, acrylic coating, wood and brick are more popular.

The damages that appear on the surface

Aluminum is also susceptible to damage. Moreover, the paint on this type of wall cladding will have to be re-applied every 5 to 10 years, because as time passes, small chips become visible because we can see the metal surface underneath. Restoring the paint will require you to remove any traces of oxidation, which takes a lot of time and makes things more complicated.

Renovating the exterior siding

What is more, repairing and replacing certain pieces can turn out to be difficult. However, since it has plenty of great qualities; it is a great option for exterior wall cladding. Lastly, another important fact is that aluminum can be recycled, which means that this material can be used for an environmentally friendly home.
