Shaped windows, arches, circles and one-offs.

Single and double angled windows, circles, gothic arches, gentle curves, and bespoke shapes. A fully opening circular porthole is reversible, for places that cannot be reached from outside: high level, above a roof, or a stairwell.

The double-glazed window in this range carries a BFRC Window Energy Rating of A+12, the most thermally efficient double-glazed PVC-u window available. Frames are CE marked, accredited by the BBA and BSI, and use a low-line gasket. The profile is the 70mm five-chamber section, with 28mm double or 44mm triple glazing, and it can use the recycled RCM reinforcement. The profile is guaranteed for up to 10 years.

PVC-u is classed as self-extinguishing: it burns only in an intense fire. Frames in this material are rated A, and commercial frames A+, in the BRE Green Guide. Washed with soapy water, and with the hardware lubricated now and then, they are the maintenance. Colour-fastness tests are part of the system, and the frames are expected to last upwards of 35 years.

Colours include white, vanilla, rosewood, golden oak, Irish oak, Beck brown, Chartwell green and gale grey.

A one-off shape is still a World Group window. Same security, same glazing, same colours, made to order rather than bought in as a special.

Fitted by our own installers. Fully employed and time-served. Never subcontracted. The profile is guaranteed for up to 10 years.

Frames do not rot, rust, warp or split, and the system is proven past 35 years. Soapy water, and a drop of lubricant on the hardware, is the upkeep. High-security locking is part of the frame, not an extra.
