Polyamide Thermal Barrier

Modern aluminium windows are exceptionally warm. Smart Systems utilizes advanced polyamide thermal barrier technology between inner and outer frames, drastically stopping heat transmission. Paired with high-efficiency argon-filled double or triple glazing to ensure low U-values and banish condensation.

Marine-Grade Powder Coating

Finished to the highest international Qualicoat marine standards. The electrostatically applied polyester powder coating will not blister, flake, fade, or corrode—even in exposed North East weather. Available in hundreds of RAL colours, including textured sensations and dual-colour combinations.

— Frequently Asked Questions

Common Questions About Aluminium Windows

Aluminium possesses substantially higher tensile strength than uPVC, allowing the window frames to be manufactured significantly thinner while supporting larger, heavier glass units. This maximizes natural daylight and provides a sleek, modern architectural aesthetic that cannot be achieved with bulkier materials.
Yes. Modern Smart Systems aluminium windows feature an advanced polyamide thermal break inserted between the inner and outer aluminium profiles. This completely breaks the thermal bridge, eliminating cold transfer and condensation while achieving an A Window Energy Rating.
Yes, the Smart Systems Alitherm Heritage system was designed specifically as a high-performance modern replacement for historic steel and Crittall-style windows. It features signature slim profiles, horizontal astragal glazing bars, and period-appropriate teardrop handles, making it ideal for heritage, Victorian, and Art Deco properties.
We provide the complete RAL colour palette with durable Qualicoat polyester powder finishes. You can choose from sleek Matt Anthracite Grey (RAL 7016), Jet Black (RAL 9005), pure White, or unique textured ‘Sensations’ metallic tactile finishes. Dual colours are also fully supported.
Smart Systems aluminium windows have an expected lifespan exceeding 40 years. The marine-grade polyester powder coating is virtually maintenance-free—requiring only an occasional wipe with soapy water. It will never rot, warp, peel, or require repainting.
