Pain point issue: Currently, most aluminum curtain walls in public and residential buildings suffer from deformation. The panels exhibit noticeable wavy distortion, accompanied by localized bulging, denting, warping, and even twisting. Is there a simple and effective solution? The answer is yes: directly increase the aluminum panel thickness.

Design recommendation: Directly increasing the total thickness of the aluminum plate and improving the stiffness of the aluminum panel is a very effective method to reduce wave deformation. This is a simple, direct, and effective method, but it is also a "cumbersome" and "costly" solution. It is more like a "strong medicine" than a "clever medicine".

Method 1: Directly use honeycomb aluminum plate

The stiffness of 10mm, 15mm, and 20mm honeycomb aluminum plates is about 23 times, 55 times, and 100 times that of 2.5mm single-layer aluminum plates. In the vast majority of building curtain wall applications, the stiffness of 10-15mm honeycomb panels is more than sufficient, which can effectively eliminate wave deformation.

Method 2: Directly using full dimensional aluminum core composite board

The stiffness of 4mm, 6mm, and 8mm full dimensional aluminum core composite panels is about 2.7 times, 9.1 times, and 22.6 times that of 2.5mm single-layer aluminum panels. In the vast majority of building curtain wall applications, 8mm full dimensional aluminum core composite panels have more than enough rigidity to eliminate wave deformation to the extreme.

Method 3: Use thickened single-layer aluminum plate

The stiffness of 3.0mm, 3.5mm, and 4.0mm single-layer aluminum plates is about 1.7 times, 2.7 times, and 4.1 times that of 2.5mm single-layer aluminum plates. Upgrading the panel from 2.5mm to 3.0-4.0mm is a highly cost-effective and highly recommended measure to improve the quality of the curtain wall and reduce wave deformation.

The above stiffness multiple results can intuitively demonstrate why honeycomb aluminum plates and full dimensional aluminum core composite plates are one of the "ultimate weapons" for solving wave deformation.

From a technical perspective, using honeycomb aluminum panels and full dimensional aluminum core composite panels to suppress wave deformation has a disruptive effect. When making decisions, the core is to strike a balance between "ultimate performance" and "high cost".
