Flush Windows

The charm of a traditional timber window and all the benefits of modern energy efficiency

Classic and contemporary, the Resurgence flush sash window blends the clean lines and elegance of a pre-1932 timber window with modern thermal efficiency - and none of the ongoing maintenance. Designed to complement character properties perfectly, as well as modern, architectural masterpieces, Resurgence grants the ultimate in versatility and style. Hand-crafted using ground-breaking, multi-chamber uPVC window system, Resurgence lacks the tell-tale overlap of traditional uPVC casement windows. Instead, the sash sits beautifully within the frame, providing a sleek, smooth exterior with a choice of beautiful finishes. Making it even more unique from its counterparts, Resurgence is glazed like a standard casement window - no bonding required. This results in less disruption during installation.


Performing as well as it looks, Resurgence offers up much more than a beautiful design.

An industry first, Resurgence's double-rebated sash provides unparalleled draught and weather-proofing. Liniar's design and development team also included the company's patented double co-extruded bubble gasket, so you can rest assured that Resurgence stands up to even the harshest weather. The design also eliminates the brush piles or external seals typically found in the shadow gap of other flush windows, providing a cleaner, sleeker finish.
