PVC-U Windows
Our PVC-U windows combine optimal thermal and acoustic insulation with 30+ stock colours and 20 additional quick-lead options. Featuring slim profiles and patented technologies, they offer timber aesthetics without maintenance requirements. Backed by ISO certifications and PAS 24 security standards, these windows deliver 35-year lifespans with recyclability through our closed-loop systems.
Composite Windows
The Linktrusion-enabled composite windows merge glass fibre strength with PVC-U efficiency, eliminating steel reinforcement. These slim-profile systems achieve A+ energy ratings while maintaining structural integrity for large openings. Certified to PAS 24 standards, they offer 48% improved thermal performance over traditional systems with full recyclability at end-of-life.
Heritage Flush Sash
Award-winning flush sash windows replicate traditional timber aesthetics with modern PVC-U benefits. Featuring equal sightlines and dummy sashes, they meet conservation area requirements while providing A-rated energy efficiency. The range includes dedicated hardware achieving 60% better weather performance than standard systems.

PAS 24-certified triple-track sliding doors offer three-panel configurations for maximum space flexibility.

The system integrates with our colour simulator for precise visualisation before installation.
