Architects have utilised aluminium cladding for years already and in 2024 it is still just as popular. Because it is in many instances the “automatic” choice, designers and installers sometimes forget what benefits aluminium offers.
It is also good to always keep the drawbacks in mind when material has to be chosen.
Various types
Although there are various types of aluminium cladding, this article discusses general benefits and drawbacks.
However, for completeness’ sake, we’ll list five available types before looking at the general pros and cons of the material.
- Solid panels made from pure aluminium sheets.
- Prefabricated cassette panels to be installed on a frame.
- Overlapping cladding designed in such a way that the panels interlock.
- Panels with a honeycomb core between two aluminium sheets.
- Perforated aluminium panels allowing light and air to pass through.
Benefits
The benefits include the following:
Cost-effective
Cost-effectiveness doesn’t mean that it’s the cheapest material but rather that any cheaper material is inferior in quality and/or needs regular costly maintenance.
Various finishes
Many different finishes are available. According to providers, the timber-look is very popular. It combines the best aluminium properties with a natural look.
Standardised sizes
Aluminium panels come in standard sizes and, usually, fit any architect-designed home. Standardised sizes also make it easy to transport the material.
Durable and weather-resistant
Although an aluminium panel can dent under direct hits, it is still very durable. It is weather-resistant and installers can use it in cold, hot, dry, or windy environments. The tiles don’t stain easily and look good for decades.
Long life and low maintenance
It requires only low maintenance and can last up to 6 or 7 decades. An annual wash-down is often all that is needed as maintenance.
Fire resistant
It meets the applicable Australian and international fire safety standards.
Drawbacks
Despite all the pros, there are also drawbacks to keep in mind regarding aluminium cladding.
Upfront cost
Although aluminium cladding is less expensive to maintain than most other materials, the upfront cost may be a negative aspect for some. The aluminium composite panels price, for instance, is higher than the upfront cost of materials such as vinyl, fibre cement, or timber.
Panels can dent when directly hit
Aluminium cladding panels might dent, but only when directly hit. Debris flying around during hurricanes or strong winds may damage some of the panels. It is recommended that they are inspected after a big storm and panels repaired if needed.
Joints need to be carefully sealed and maintained
During installation, the installers have to ensure that all the joints are carefully sealed. If the panel joints are not sealed properly, water might accumulate between the cladding and the wall. From time to time the joints have to be inspected and repaired if needed.
Noise caused by rain
Some people don’t like the noise when rain or hail comes into contact with the cladding. However, the noise can be reduced with adequate insulation.
Conclusion
Despite a few drawbacks aluminium is still a very popular cladding material in 2024.
