With narrow sightlines and a U-value as low as 1.4 W/m2K, the W50 TB steel window 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 W50 TB steel windows are manufactured differently from traditional solid, hot-rolled steel section windows.
West Leigh has introduced the W50 TB 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 W50 TB provides incredible versatility.
W50 TB comprises the same forms, proportions and overlapping effects of the original 20th-century hot-rolled steel window profiles, refined by cold rolling technology. The innovative high-density polyurethane isolator used as a thermal barrier, together with the possibility of housing low emissivity glass up to 37 mm, allow them to fully respond to current regulations and contemporary needs for comfort, including in harsher weather conditions where windows made from solid steel profiles may not be sufficient. The range is completed by a wide range of exclusive fittings in several finishes, reproduced from original designs of the modern era. Any kind of inward or outward openings are possible.
Windows and Doors made from Cold Rolled Steel profiles are pre-coated with a zinc rich primer and then coated
with one of the many RAL colours by powder coating
An extensive range of colours is available (any standard RAL reference).

The durability and high performance of steel windows can be enhanced even further if good maintenance practices are observed.
Frames should be cleaned at regular intervals using a mild, non-alkaline detergent in warm water, applied with a soft cloth or sponge.
Glazing and perimeter sealants should be inspected on an annual basis and appropriate maintenance action should be taken.
All hinges, pivots, handles, stays and other mechanical parts should be checked for operation, kept free of excessive paint build-up and lightly lubricated.
Full O & M Manuals (Operation and Maintenance Manuals) are supplied by West Leigh upon request on any new window project.
