What is the lifespan of aluminum composite panels?

Aluminum composite panels (ACP) are a popular material in decorative architectural applications such as aluminum ceiling (天花) and curtain wall (幕墙), and since it is made so well, it tends to last forever. Usually, the service life of ACPs varies from 20 to 30 years based on maintenance, quality of installation, exposure to extreme environmental conditions, etc. Not to mention that these panels, in the context of aluminum ceilings and curtain walls, will have a coated surface such as PVDF or polyester, which gives them greater weathering, corrosion resistance, and UV (ultraviolet) resistance.

As a result, the longevity of aluminum ceilings as an interior solution is improved, as compared to being outdoors, where all kinds of weather conditions lead to deterioration. They can last even longer if they are regularly maintained by cleaning and checking for mechanical damage.

Although in the case of aluminum curtain walls they are exposed to more severe weather conditions, high quality ACP's are made to endure such challenges. They have two sheets of aluminum front and back with a core material in between, which gives their handlestrips a multihull profile that can withstand both wind and water entry, as well as prevent heat transfer.

Proper installation is critical; aluminum composite panels installed incorrectly can prematurely fail due to water leaking through jointing causes panel delamination, and corrosion, etc. This is why it’s crucial to bring in account professionals to install and regularly inspect the panels, keeping their aesthetic and structural integrity intact over time.

Therefore finally, the service life of the aluminum composite panel under conventional conditions is 20 to 30 years, and determining factors such as the choice of materials used for production, installation and maintenance play a dominant role in determining the factors of service life, especially for the special applications such as aluminum ceilings and curtain walls.
