Modern Glass Technology by IQ Glass

Large Opening Windows

Steel framed windows are strong and robust and can be engineered to create large opening windows and create an impressive impact on an architectural design.

Our slim framed Mondrian Steel Windows can create an extremely slender framing finish but if larger opening windows are required IQ can create larger, bespoke steel windows to suit your architectural design project.

Thanks to the inherent strength of steel window frames, when using steel IQ can create opening windows to impressive sizes complete with a full thermal break throughout the steel frame.

When using our thermally broken steel frames we can create a steel opening window up to 4m in height with high levels of thermal performance and insulation with Uw values less than 1.0 W/m2K possible.

These large steel windows can be created with either a triple or double glazed unit, maintaining a clean steel window profile of only 85mm wide.

Steel Frame Design

Our steel windows are created with neat, clean edges and corners to enable them be used on high specification architectural designs where attention to detail is a high priority.

The steel frames used in the fabrication of our architectural steel windows can be either Galvanised Steel powder coated to your preferred RAL colour, Stainless Steel, Corten Steel or Patinated Bronze.

The availability of these thermally broken steel windows in a range of metals creates a unique steel window design and can be used to create striking finishes to architectural designs.

There are also a range of window handles available to choose from to ensure that your entire steel window design perfectly suits your project specifications. These handles are also available in a range of architectural metals to suit your steel window frames.

Bespoke mullion and transom designs are also an option in order to create a traditional steel window design in larger, more impressive sizes or enhanced thermal performance.
