The 'REAsteel W40' range of profiles is an evolutionary development of the traditional hot rolled steel window. The generic attributes of slim sightlines, difficult to match in the bulky profiles of other materials, have been retained. The opening vents incorporate the provision of dual air seals.

The system was designed to accommodate 24mm sealed glass units. As most UK applications have wind loading requirements within the capacity of 4mm glass, the benefits of higher insulation values from a 16mm air space are available. The methods of glazing permit the ventilation and drainage of the glass unit perimeter and gasket glazing can be available.

The system will allow the glass to be offered to the frames from either the inside or the outside.

The introduction of the dual weatherseals has gone a long way towards the improvements that have been made. Extensive laboratory testing was undertaken throughout all stages of development and improvements in the resistance to air and water penetration are the result.

Composite assemblies of steel windows are formed by joining single units to each other using mullions and/or transoms of appropriate dimensions to provide support. Generally the coupling bars take on a fin like appearance, however, there can be occasions when either for strength, or as a feature, tubular steel RHS profiles can be introduced.

After fabrication steel windows are hot dip galvanised to BSEN ISO 1461 (1999) and, where specified, polyester powder coated to BS6497 in a wide range of standard colours.
