Composite Doors
Our composite doors combine advanced security features with aesthetic versatility. Featuring reinforced GRP skins and Ultion locks, they offer superior insulation and durability. Available in 59 colours with multiple glazing options, these doors provide both kerb appeal and minimal maintenance requirements for residential properties.
UPVC Casement Windows
Manufactured to precise specifications, our UPVC casement windows deliver energy efficiency and low maintenance. The range includes woodgrain and smooth finishes with optional decorative glazing. Designed for easy operation and enhanced security through multi-point locking systems.
Aluminium Bi-Fold Doors
Contemporary aluminium bi-fold systems create seamless indoor-outdoor transitions. Featuring slim sightlines and thermal break technology, these doors accommodate large openings while maintaining energy efficiency. Available in custom RAL colours with high-security locking mechanisms.
Conservatory Roofs
Our conservatory roofs combine insulation performance with natural light optimisation. The Equinox system offers tiled options while the Skypod provides glass solutions with solar control glazing. Both maintain structural integrity and weather resistance for year-round usability.
Flush Sash Windows
Contemporary flush sash windows replicate traditional timber aesthetics with modern UPVC benefits. Their streamlined design reduces air infiltration while maintaining heritage compliance. Available with optional trickle vents and enhanced security hardware.
