Our Window Systems
We expertly manufacture a diverse range of steel window systems to cater to specific architectural styles and functional demands.
- W20 Steel Windows: These traditional heavy-duty windows, with their distinctive 32mm wide profile and 5mm thick flanges, are renowned for their strength and longevity. Originally designed for commercial and industrial applications, W20 windows are now cherished for their classic aesthetic and robustness in residential settings.
- W30 Steel Windows: This slimline derivative of the W20 system offers a modern and elegant solution for outward-opening double glazed domestic and light commercial applications. Featuring double weather seals and fully drained and ventilated glazing, the W30 provides both style and weather protection.
- W40 Steel Windows: Building on the heritage of the W20, these windows maintain the characteristic casement sight lines while offering the benefit of wider 40mm profiles. This wider profile accommodates double glazing with 26mm thick units, ensuring exceptional thermal performance.
- SMW Standard Metal Windows: As the name suggests, these windows stand as a testament to enduring classic design. Their 25mm wide profile and 3mm thick flanges, along with standard 500 or 600mm modules, make them perfectly suited for renovation projects where authenticity is paramount.
We believe that our expertise, coupled with our dedication to customer satisfaction, sets us apart as a leading provider of bespoke steel windows in the UK.
