Double Glazing
Our double glazing solutions combine advanced thermal efficiency with robust security features. Using A+ rated glass, they reduce heat loss, lower energy bills, and enhance home comfort. The sealed units trap a thermal blanket of air, preventing cold ingress while maintaining sound insulation. Available in uPVC, aluminium, or timber, our windows meet Building Regulations and are ideal for modern and heritage properties. With over 30 years of expertise, we ensure precise installations that boost property value and sustainability.
Residence Collection
The Residence Collection offers traditional aesthetics with modern performance. These windows comply with conservation area guidelines while delivering U-values as low as 0.8 with triple glazing. Their internally beaded design enhances security and thermal efficiency, preventing warping or rot. Available in R9 and R7 profiles, they feature low-maintenance materials and customizable colours. Ideal for listed buildings or period homes, they balance elegance with energy savings, reducing carbon footprints without compromising on style.
Conservatory Roofs
Transform your conservatory with our solid, thermally efficient roofs. These lantern or tiled designs eliminate overheating in summer and heat loss in winter, creating year-round usable space. The insulated panels meet Building Regulations and reduce noise from rain or wind. Compatible with existing frameworks, they offer a seamless upgrade without structural changes. With a 20-year guarantee, our roofs enhance comfort, value, and aesthetics, making conservatories a functional extension of your home.
Composite Doors
Our composite doors merge durability with style, featuring multi-point locking systems and reinforced frames. The thermally broken profiles prevent heat transfer, achieving A+ energy ratings. Available in woodgrain or RAL colours, they resist warping and fading, requiring minimal maintenance. With optional glazed panels and bespoke configurations, they enhance kerb appeal while meeting PAS2030 standards. Each door is precision-fitted to ensure security, energy efficiency, and long-term performance.
Aluminium Bi-Fold Doors
Origin aluminium bi-fold doors provide sleek, space-saving access to gardens with slim sightlines and seamless operation. The multi-point locks and reinforced frames ensure security, while EPDM seals prevent draughts. Available in 150+ colours, they integrate with smart home systems for convenience. Designed for thermal efficiency, they retain heat in winter and reduce cooling costs in summer. Ideal for modern extensions or conservatories, they combine style with functionality for uninterrupted indoor-outdoor living.
