Dual Turn Windows

If you're looking for a window that combines the elegance of traditional sliding sash windows with the practicality of casements, then our Dual Turn windows are the perfect fit. Carefully designed for optimal performance, our Dual Turn windows offer the best of both worlds. From the exterior, they have the classic look of traditional timber sliding sash windows, with traditional sightlines, narrow profiles, and a setback lower sash. The interior features decorative horns, ovolo mouldings, and the option of fine 22mm glazing bars for a traditional appearance. The functional design of the Dual Turn window allows both sashes to open outwards for efficient cleaning from the inside. With special egress hardware, the bottom sash can also be used as a safe and easy means of fire escape. Our Dual Turn windows are PAS24 tested and have Secured by Design' status, ensuring superior weather resistance, thermal and acoustic efficiency, and top-tier security.

Timber and Alu Clad Windows and Doors

We offer two ranges of timber casement windows, designed with a wide variety of design and performance features. Our alu clad windows and doors provide a highly durable, low-maintenance, and versatile solution for domestic and commercial applications. Our alu clad products are designed with a durable aluminium exterior and a warm timber interior, providing the best of both worlds.
