Roseview Windows is the UK’s leading specialist manufacturer of uPVC sliding sash windows, with a heritage that dates back to 1977. With over 44 years of experience, Roseview has played a pioneering role in the development of timber-alternative sash windows, becoming the first company in the UK to specialise in this product type in 1985. Since then, the company has remained at the forefront of innovation, combining traditional aesthetics with cutting-edge performance.
Advanced manufacturing techniques, including in-house foiling and precision engineering, allow for a highly realistic timber effect while delivering the benefits of modern uPVC construction. Features such as run-through horns, traditional detailing and innovative chamber-filling technology ensure that every window achieves both visual accuracy and long-term performance.
Innovation has always been central to Roseview’s success. The company has continually developed industry-first solutions, from seamless technology and bespoke midrails to patented advancements such as ThermoVFlex, designed to achieve outstanding energy efficiency without the need for specialist glazing. This dedication to progress has earned Roseview multiple industry awards, including recognition for both product excellence and customer care.
Manufactured at their advanced facility in Olney, Buckinghamshire, Roseview produces tens of thousands of sash windows annually, supported by a highly skilled workforce and state-of-the-art CNC machining centres. Every product is tracked through a fully integrated production system, ensuring precision, consistency and quality from manufacture through to installation.
