Windows: Welcome

Bespoke solutions

Adaptable, high-performing and secure windows to suit any budget.

Our slim style uPVC casement windows are manufactured in the South West to meet the highest standards of quality and security, without compromising on aesthetic appeal. A 10mm coverage seal against the outer frame, gives the highest rating of weather protection against the changeable UK weather. This far exceeds most other rival systems on the market.

This window system is uniquely designed to have interchangeable properties across the entire range meaning it is versatile enough to be produced in any configuration or style you can envisage. Large openings to small fanlight windows are all possible. Our bespoke, made to measure casement windows are flexible to meet both traditional and contemporary homes thanks to the choice of colours, hardware and decorative finishes available.

Our flush casements are a highly adaptable system with a coloured foil range that makes it indistinguishable from a timber alternative.
