Alitherm Heritage Windows

Heritage Aluminium Windows: The Modern Solution for Classic Designs

Heritage aluminium windows offer a refined, modern alternative to traditional steel or timber windows, making them the perfect solution for projects involving sensitive refurbishment or heritage properties.

Designed with Smart’s innovative polyamide thermal break technology, these windows provide exceptional insulation, preventing heat loss and reducing energy bills. This modern solution ensures compliance with strict planning regulations while maintaining the charm and character required for listed buildings and conservation areas.

Heritage aluminium windows are lightweight yet incredibly strong, offering a long-lasting, low-maintenance option. Unlike steel or wood, aluminium will not rust, rot, or deteriorate, providing exceptional durability and longevity. For homeowners and developers, heritage windows require minimal upkeep, with no need for repainting or revarnishing over time. Wipe them clean, and they will maintain their elegant appearance for years.

Alitherm Heritage Windows: Bringing Versatility and Performance Together

The Alitherm Heritage range is ideal for projects that need to replicate traditional steel windows while benefiting from modern performance. These windows’ slim sightlines and elegant finish are perfect for listed buildings or large-scale renovation projects. Available in a range of configurations—including fixed, single or double sash, side-hung, top-hung, tilt & turn, and pivot windows—Alitherm Heritage windows offer flexibility for any architectural design.

Each window in the Alitherm Heritage collection is designed to stack as horizontal modules joined by horizontal couplers. This allows the creation of multi-part window installations with a cohesive aesthetic. The marine-quality polyester powder coat finish, available in single or dual colours, ensures an attractive, durable exterior that can withstand the harshest conditions.

With an outstanding U Value of 1.5 W/m²K when fitted with suitable glazing, Alitherm Heritage windows are an excellent energy-efficient option. Integrating the polyamide thermal break further enhances thermal performance, providing comfort and sustainability in equal measure.
