Why UPVC windows?

UPVC is still the most popular window material in the UK: durable, low-maintenance, thermally efficient and good value. Modern UPVC is a big step up from the windows of 15–20 years ago, with slimmer profiles, better locks and far better thermal performance.

It does not rot, warp, flake or need repainting — a wipe with soapy water is all the upkeep needed — and the frames are reinforced with galvanised steel for strength.

Window styles available

Casement windows

The most common style — side or top-hung sashes that open outward, in single or multi-sash layouts, in standard and sculptured profiles.

Tilt-and-turn windows

Popular for upper floors and flats: the sash tilts in for ventilation or swings fully inward for easy, safe cleaning.

Flush sash windows

Designed to mimic traditional timber, with the sash sitting flush to the frame — popular in conservation areas and period homes.

Performance

Energy efficiency

All our UPVC windows are A-rated as standard, not an upgrade. Multi-chambered profiles, warm-edge spacer bars, argon-filled units and low-E glass cut heat loss by up to 80% compared with old single glazing.

Finishes

Colours and finishes

White, anthracite grey, black, cream, chartwell green, and woodgrain foils (oak, rosewood, mahogany), with dual-colour options such as grey outside and white inside.
