The R7 system offers a truly refined aesthetic with its completely flush appearance on both internal and external faces. With a sleek 75 mm multi-chambered profile, it delivers A+ energy ratings and remarkable thermal and acoustic performance. Depending on glazing choice, it achieves U-values as low as 0.8 W/m²K with triple glazing, and requires virtually no maintenance—just a simple wipe-clean to keep it looking pristine.

The R7 range is versatile in design and highly customisable, embracing both heritage and contemporary styles with joint options like HeritageWeld, mitre, and Graf welding. Whether installed in traditional conservation areas or modern new builds, with a palette of over 20 colours and elegant hardware including Monkey Tail and Pear Drop handles, R7 brings polished simplicity to any home. It’s available across a wide selection of formats—from casement and shaped windows to French doors and orangeries.
