A Fully Reversible PVC-U Window for Safe, High-Rise Living

The Fully Reversible Window is a high-performance PVC-U window system designed for medium to high-rise residential and commercial buildings where safe cleaning, secure ventilation, and long-term durability are essential. With a 180° reversible action that allows the external face of the window to be cleaned from inside the building, this system is ideal for hard-to-access locations such as apartment blocks, student accommodation, and care homes.

Manufactured by Epwin Window Systems, the Fully Reversible Window is engineered to meet the latest UK Building Regulations and offers a practical, low-maintenance solution for modern developments and refurbishment projects.
