Our A-rated PVCu windows feature Liniar's EnergyPlus profiles with triple glazing achieving 0.84W/mk thermal efficiency. Available in casement, tilt & turn, and sash designs, they combine security with low maintenance. Manufactured in the UK using 100% lead-free materials, these windows reduce energy bills while maintaining traditional aesthetics.
Composite Doors
Thermally efficient composite doors incorporate multi-point locking systems and internally beaded glazing for enhanced security. Available in various panel options and finishes, they offer 350-year recyclability and 0.84W/mk thermal performance. Our installations include half-glazed and full-panel designs suitable for both traditional and contemporary properties.

Bespoke conservatories range from classic lean-to designs to modern glass extensions with pitched skylights. We offer tiled roof options achieving 0.15W/mk U-values, creating year-round usable spaces.

I am very pleased with my French doors and new wall. The standard of work was excellent and you left the site immaculate.
