Advantages and Disadvantages of Aluminum Sandwich Panels

The major construction projects in Dubai are openly adopting aluminum sandwich panels. It is one of the most popular materials in the modern construction sector. However, if you are not familiar with it, it is common to feel curious about these panels.

That is why in this article, we are exploring the aluminum sandwich panels, their advantages and disadvantages, especially in Dubai’s landscape.

​Let’s have a look at:

What are Aluminum Sandwich Panels?

Construction materials are of different types. For instance, cement, bricks, and steel rods are essential for foundational stability. Aluminum sandwich panels or Aluminum composite panels (ACP), on the other hand, act like a skin of a structure, adding aesthetic value while also providing protection against environmental damage, like UV rays, sandstorms, etc.

​The panels are manufactured by sandwiching two aluminum sheets with a core material in between. This is done under very high temperature and pressure, so the bond is strong and doesn’t easily pull apart. If you choose a reliable manufacturer like Viva ACP, your panels will last for decades with minimal maintenance.

​Advantages of Aluminum Sandwich Panels

Modern construction comes with several challenges. Aluminum sandwich panels offer exceptional advantages, including:

1. Heat Resistance and Thermal Insulation

Surrounded by desert, Dubai's temperature can rise up to 45°C (113°F). ACP sheets are resistant to high heat and maintain their structural integrity. They also offer heat insulation thanks to their mineral core and polyethylene core. The core offers low thermal conductivity, hence the external heat doesn’t influence the temperature inside the building.

2. Durability Against Sandstorms

Sandstorms are quite frequent in Dubai, especially in the summer months. The speed can reach up to 35–100 km/h (22–62 mph) and can damage the exterior part of the building. You might have to spend a large amount of time and money cleaning and repairing. But with Aluminum sandwich panels’ smooth coated surface, which resists abrasion, so you don’t need to worry about scratches. And cleaning these panels is super easy. A mild detergent, a soft sponge, and clean water will do the job.

3. UV and Weather Resistance

Just like our clothes fade, if we leave them to dry in the sun for too long, the same happens with cladding material. Since they are always exposed to the sun and harsh weather conditions, they start to degrade. Thus, aluminum sandwich panels often come with a protective coating of Polyvinylidene Fluoride (PVDF) paint, which makes them material immune to UV rays.

4. Lightweight and Flexible for High-Rise Construction

Another advantage of installing aluminum sandwich panels in Dubai’s commercial structures is that the material is lightweight. This means they are easy to transport from one place to another. You can use them easily as well, unlike stone or other heavy materials. They actually reduce the structural load of the building, which is very important to maintain balance between the building’s form and function.

5. Fire Safety Compliance

When you choose a fire-retardant ACP panel, it enhances the safety of your building. They reduce the devastating effect of fire. Depending on the core material used, aluminum sandwich panels can help with safe evacuation. Viva ACP’s FR class A2 & B comply with EN 13501 and ASTM D1929, and provide 2 hours of safety against fire.

6. Aesthetic Versatility

Commercial buildings need to be appealing. That's how they attract customers and build a strong presence. Aluminum sandwich panels match the aesthetic standard by providing a wide range of options. Whether you want the rust feel of stone or metal, the glossy appearance, or the wooden finish, these panels are versatile and come up with customization as well.

7. Corrosion Resistance in Coastal Areas

For luxury hotels and restaurants in coastal areas of Dubai, choosing a corrosion-resistant material will provide long-term value. This is because many traditional materials rust when they come in contact with humidity. Aluminum in ACP panels, on the other hand, creates a protective barrier against moisture damage, warping, or delamination.

Disadvantages of Aluminum Sandwich Panels

ACP panels are a reliable material that can last for decades. However, when choosing a manufacturer, you need to consider the quality of the material as well as the proper installation process. Or you may have to suffer from these issues, which can be considered disadvantages:

1. Heat Expansion Issues

Since the temperature in Dubai can be quite high sometimes, the panels might expand.  Poor installation or a lack of proper expansion joints can cause panel deformation or loosening over time.

2. Risk of Non-Compliant Panels

Low-quality or non-fire-rated cladding materials can increase safety concerns. If you don’t thoroughly look and choose cheaper, non-compliant panels, it can pose serious risks and violate building codes.

3. High Initial Cost

Installing high-quality ACP panels might come with a high up-front cost. Aside from the charges of the material, you have to consider installation as well. As poor installation can cause frequent maintenance.

4. Surface Heating

While ASPs reduce heat transfer indoors, the aluminum exterior absorbs sunlight, making the surface extremely hot to the touch. If you are installing it in a pedestrian-friendly zone or low-rise facades, it is something you should keep in mind.

Final thoughts

No construction material is perfect. What you can do is choose the most convenient one for your structure. Aluminum sandwich panels are growing in popularity because they offer solutions to many problems builders and construction companies have, when using traditional materials. For instance, rusting, heavy weight, fire safety, UV radiation, thermal insulation, and so on. If you also suffered the same, then consider switching to an ACP sheet from a reliable manufacturer, like Viva ACP. With 30+ years of experience, they are one of the leading ACP manufacturers in Asia.

FAQs

Q.1. What are aluminum sandwich panels (ACP) used for in construction?

Aluminum sandwich panels are primarily used as external cladding or façade material in buildings. They add aesthetics, protect the structure from weather damage, and improve insulation.

Q.2. How do aluminum sandwich panels perform in Dubai’s extreme heat?

High-quality ACP panels are heat-resistant and thermally insulated, meaning they can withstand temperatures up to 45°C and beyond without losing structural strength.

Q.3. Are aluminum sandwich panels safe against fire?

Yes, if you choose fire-retardant ACP panels. For example, FR Class A2 & B panels meet international fire safety standards and provide up to 2 hours of fire resistance. Non-compliant or low-quality panels, however, pose risks.

Q.4 How long do aluminum sandwich panels last?

When purchased from a certified manufacturer and installed correctly, ACP panels can last for decades while maintaining their strength and appearance.
