Thermally Broken

Ideal for new build and renovation projects where energy efficiency and aesthetics and key, the new W50TB steel window offers narrow sightlines and a U-value as low as 1.4 W/m2k, depending on the glazing unit employed. The use of the system has been pioneered in the UK by West Leigh, working closely with Swiss designer and supplier, Ottostumm. It is based on highly engineered, thermally broken steel sections designed to closely replicate the character of the traditional W20 steel window.

The design of the thermally broken profile means that W50TB steel windows are manufactured differently from traditional solid, hot-rolled steel section windows. With this in mind, West Leigh, a member of the Steel Window Association, developed new window manufacturing techniques and appropriate paint applications. In the twelve months since launching the W50TB profile, the company has successfully employed it to fulfil over £1 million of supply and install orders.

West Leigh has introduced the W50TB steel window to extend the range of solutions available to specifiers, especially in the new build sector where outstanding contemporary architecture is required. Offering all the benefits traditionally associated with steel windows, including slender profiles, large panes of glass, good light transmission and large opening windows, the W50TB provides incredible versatility.
