PVCu Windows and Doors
Our PVCu windows and doors combine durability with modern design. Available in standard white or custom RAL colours, they offer low maintenance and long-term aesthetic appeal. The high-gloss finish resists dirt buildup, while optional dual-tone finishes allow interior and exterior colour differentiation. Energy-efficient profiles ensure thermal performance meets current standards.
Aluminium Windows and Patios
Aluminium windows and patios provide sleek, contemporary solutions with exceptional strength-to-weight ratios. Over 400 RAL colour options and multiple finishes (matte, satin, gloss) allow complete customisation. Durable powder-coated surfaces maintain appearance for 25+ years, with thermal break technology enhancing energy efficiency in residential and commercial applications.
Composite Doors
Composite doors feature reinforced GRP skins over high-density foam cores for superior insulation and security. Multi-point locking systems with 10mm engagement hooks meet ERA Five Star Guarantee standards. Available with optional glass panels, decorative ironmongery, and dual-skin colour options to complement property aesthetics while maintaining robust security features.
Conservatories
We manufacture conservatories using thermally efficient profiles and low-E glass to create year-round living spaces. Options include Victorian, Edwardian, and lean-to designs with custom roof and window configurations. Aluminium or PVCu frameworks ensure structural integrity while maximising natural light transmission for enhanced indoor environments.
Bi-Fold Doors
Our bi-fold doors provide seamless transitions between indoor and outdoor spaces. Precision-engineered aluminium or PVCu profiles accommodate multiple panel configurations with minimal sightlines. High-performance rollers ensure smooth operation, while advanced weather seals maintain thermal efficiency when closed. Available in bespoke sizes and finishes for residential and commercial properties.
