For clients seeking the perfect balance of modern style, robust performance, and long-term value, triple glazed uPVC-aluminium windows are a standout choice.
These hybrid systems, such as Internorm’s KF series and DAKO’s DPQ – 82 AL systems, combine the sleek, architectural finish of aluminium on the exterior with the multi-chamber insulation and easy maintenance of uPVC inside. The result is a visually striking, highly durable window that fits seamlessly into both minimalist new builds and design-led commercial or self-build projects. Slim sightlines, customisable finishes, and hidden hardware options allow these systems to blend beautifully with high-end façades while maximising natural light and interior comfort.
Behind their clean aesthetics, uPVC-aluminium windows offer industry-leading performance. With U-values as low as 0.62 W/m²K, products like Internorm’s KF 510 and DAKO’s DPQ – 82 Thermo AL easily meet and exceed Passive House and fabric-first requirements. The multi-chamber uPVC core provides excellent thermal and acoustic insulation, while the aluminium cladding enhances weather resistance and structural integrity — making them ideal for high-exposure or multi-storey applications.
Advanced features such as triple sealing, integrated ventilation options, and secure locking mechanisms offer the ultimate in comfort, efficiency, and security. For those designing the future of energy-efficient living, uPVC-aluminium hybrid windows deliver premium performance with refined design versatility.
