Modern architecture is no longer limited to the use of steel, glass, and reinforced concrete; it has seen the introduction of many building materials and architectural elements, and one popular example is aluminium bonded panels. They may be often used as a design element, but they’re also functional and aid the structure in many ways. They come in different colors and sizes, but you should also be aware of how durable they are. In this article, we’ll guide you on how to ensure the durability of aluminium bonded panels for facades through several key features and factors.

What are aluminum bonded panels?

Aluminium bonded panels (ABPs), as their name suggests, are aluminium sheets bonded together by a core made of plastic. They are sometimes referred to as aluminium composite panels (ACP) and are frequently used in exteriors as part of a building’s façade. Speaking of façades, aluminium bonded panels for façades are fashioned into different colors and surface finishes, adding a point of interest and appeal to structures, which is why it’s one of the most popularly used materials as of late.

Factors you need to consider to ensure aluminium bonded panels are durable.

Like most building materials, aluminium bonded panels’ durability is founded on their quality. This can be further broken down into the following factors:

Reputable manufacturer. When choosing ABP, it’s crucial to purchase it from a well-known and trusted manufacturer with a good track record. There’s a reason why they’re known in the industry, and it’s because manufacturers like these have certifications that prove their products are made of high-quality materials that passed industry standards. Purchasing from them may be costlier upfront, but it’s rewarding in the long run since their ABPs guarantee durability.

Panel composition. As stated earlier, ABPs are made up of two aluminium sheets bonded together by a plastic core. The plastic cores vary and have their own unique traits and durability. The most commonly used one in the market is the high-density polyethylene (HDPE) because of its firm bearing. Another popular option is the fire-retardant core with strong fire and impact resistance.

Surface finish. The ABP’s surface finish extends beyond aesthetics. ABPs may be used as a decorative element, but they also have a functional role, which is why choosing the right surface finish is important. Powder coating, PVDF painting (polyvinylidene fluoride), and marine-grade aluminium are three types of surface finishes. All of them offer corrosion and heat resistance but to varying levels. 

When choosing the type of finish for your ABP, select the ones that are most needed in your area. Think of it this way: Structures that are situated in coastal areas should focus more on the ABP’s corrosion resistance, while structures located in hotter regions should opt for surface finishes that offer the best UV resistance.

These factors are focused on the ABP’s actual characteristics, but there are also external factors that you should be mindful of when making your choice.

Proper installation. Even if you’ve acquired the best ABP available in the market, it will all be for naught if it’s not installed properly. Since ABPs are mounted into the substructure, the latter must also be sturdy enough to carry its own weight and the ABPs, too. It has to withstand extreme pressure and the wind load, among many other things. Call your local manufacturer for recommendations, but if you want foolproof choices, aluminum and galvanized steel are tried and tested favorites.

Maintenance and care. Just because the ABP has corrosion-resistant and heat-resistant properties doesn’t mean it’s not subject to regular cleaning. Proper and regular maintenance is also needed to ensure the ABP’s longevity, durability, and aesthetics.
