Glass and Aluminium Materials Comparison Matrix

Powder coating applies a baked-on organic paint layer to the aluminium, offering a massive range of colors and excellent impact resistance. Anodizing is an electrochemical process that converts the metal surface into a durable, corrosion-resistant oxide finish that cannot peel or flake. For coastal environments within five kilometers of the ocean, high-micron anodizing or marine-grade powder coating is mandatory to prevent salt damage.

A thermal break is a continuous, low-conductive polyamide barrier placed between the interior and exterior sections of an aluminium profile. This barrier stops heat and cold from conducting through the highly conductive metal frame. Using thermally broken frames is essential for preventing interior condensation and meeting strict modern energy efficiency building codes.

Specify laminated glass when your project requires acoustic dampening, UV protection, or overhead safety, as it holds together when broken. Toughened glass should be used where high impact resistance is needed, such as low-level glazing or glass doors, because it breaks into small, blunt pieces. For high-security shopfronts, laminated glass is the standard choice because it maintains a physical barrier even after being fractured.

The U-value measures how much heat escapes through the window, meaning a lower number indicates better insulation during winter. The Solar Heat Gain Coefficient (SHGC) measures how much solar radiation passes through the glass, where a lower number blocks more heat from entering in summer. Getting the right balance of these two metrics is what ensures the building remains comfortable and compliant year-round.
