Non-thermal aluminum systems are considered an intermediate solution between standard aluminum structures and thermal break systems. While they do not offer full thermal insulation, they are a suitable choice for applications where complete energy optimization is not required. Key features of non-thermal systems include high strength and durability, the ability to be finished in various coating methods such as electrostatic powder coating, anodizing, and wood-effect finishes, as well as corrosion resistance, flexibility, and ease of machining.
