SL38 Window

Inspired by the distinctive proportions of traditional steel windows, the SL38 features a slender profile that makes it particularly well suited to sensitive renovation projects. It retains the refined appearance of a steel-framed window while offering the enhanced thermal performance and durability of modern aluminium.

Available as both inward and outward opening, the SL38 can be tailored to complement a wide range of architectural styles. Three design variants provide further flexibility, allowing the window to be specified to suit the character of the building.

Despite its exceptionally slim appearance, the SL38 accommodates both double and triple glazing, providing excellent levels of thermal insulation.

The result is a sophisticated balance of slim sightlines, outstanding insulation and durable aluminium construction — making the SL38 an ideal choice where architectural detail and modern performance are equally important.

The SL38 is also available as part of a corresponding door system, allowing windows and doors to be specified together for a consistent aesthetic throughout the property.
