The UK’s first double-rebated uPVC flush sash window, Resurgence by Liniar takes the timber-alternative window concept to whole new levels of security and beautiful aesthetics. They offer the realistic charm and appearance of a beautifully flush timber window combined with all the benefits of modern energy efficiency. 

The Resurgence flush window design eliminates unsightly visible gaskets between the frame and the sash (known as the shadow gap) thanks to an innovative double-rebated seal. This not only provides a cleaner appearance but also results in unparalleled weather performance and energy efficiency. Resurgence is foiled on the interior surfaces too, providing a realistic timber-look finish even when the window is open.
