Timber Sash Windows
Traditional timber sash windows combine period character with modern performance. Our slim-sectional designs maintain historical accuracy while incorporating double glazing for thermal efficiency. Available in both traditional box sash and spring-balanced variants, these windows feature multi-point locking systems and warp-resistant engineered timber. Each unit includes concealed trickle vents for ventilation compliance and security features preventing external glass removal.
Casement Windows
Bespoke timber casement windows offer superior insulation and security. Available as flush or Edwardian styles, they feature hidden multi-point locks and draught excluders. Constructed from knot-free engineered redwood, meranti, or oak, these windows resist warping while maintaining traditional aesthetics. Customisation options include dual-colour finishes and specialist glazing like self-cleaning or acoustic glass.
Entrance Doors
Handcrafted timber entrance doors combine security with visual appeal. Available in contemporary or period styles, they feature advanced locking systems and warp-resistant construction. Factory-finished with 8-year paint guarantees, these doors incorporate concealed hinges and optional sidelights. Custom designs replicate existing patterns or create unique entrance statements while maintaining thermal efficiency.
Bi-Fold Doors
Engineered timber bi-fold doors maximise light transmission and outdoor connection. Featuring continuous tracks and flush thresholds, they allow seamless indoor-outdoor transitions. Security features include hidden multi-point locks and toughened glass panels. Available in custom RAL colours with optional dual-finish exteriors, these doors maintain thermal performance through krypton gas-filled units.
French Doors
Traditional timber French doors offer timeless elegance with modern functionality. Available with hidden hinge technology or traditional parliament hinges, they provide secure access to outdoor spaces. Double-glazed units with argon gas ensure thermal efficiency while engineered timber frames resist warping. Custom options include decorative glazing and bespoke ironmongery to match property aesthetics.
