Windows
We manufacture and supply high-quality uPVC windows with advanced thermal insulation properties. Our windows feature multi-chambered profiles and energy-efficient glazing options that reduce heat loss by up to 30%. Available in various styles including casement, tilt-and-turn, and heritage designs, our windows enhance property security while maintaining aesthetic appeal. Each installation includes draught-proofing and weather sealing to maximise energy savings.
Conservatories
Our bespoke conservatories combine modern design with energy-efficient construction. Using thermally broken aluminium frames and solar-controlled glazing, these structures maintain comfortable temperatures year-round. We offer lean-to, Edwardian, and orangery styles with optional underfloor heating integration. All conservatories include safety glass and security locking systems while complying with current building regulations for thermal performance.
Bi-fold Doors
Our premium bi-fold door systems create seamless transitions between indoor and outdoor spaces. Featuring slim sightlines and high-performance weather seals, these doors incorporate multi-point locking systems for enhanced security. Available in configurations with up to 7 panels, they provide excellent thermal efficiency with U-values as low as 1.4 W/mK. Optional integrated blinds and self-cleaning glass enhance functionality.
uPVC Doors
We supply and install reinforced uPVC doors with advanced security features including anti-snap cylinder locks and multi-point locking systems. Our composite doors achieve U-values below 1.0 W/mK for superior insulation. Available in traditional and contemporary designs, they include optional glazed panels with decorative ironmongery. All doors undergo rigorous testing for weather resistance and structural integrity.
Aluminium Windows
Our aluminium window systems combine slim profiles with exceptional thermal performance. Using polyamide thermal breaks and double-glazed units, these windows achieve U-values down to 1.2 W/mK. Available in powder-coated finishes with custom colour options, they offer high corrosion resistance for coastal properties. The windows incorporate trickle vents for controlled ventilation and meet Secured by Design standards.
