Flush Sash Windows

"If you’re lucky enough to live in a period property, you’ll know there can be some drawbacks, too. "

While, heritage buildings look and feel amazing, more often than not they come with draughty living conditions due to badly fitting timber windows or ineffective single glazing.

If you wish to retain the simple, classic lines of traditional timber-framed windows, but want all the many benefits of a modern-day uPVC system, too. FlushSash uPVC windows are the perfect solution.


The early 19th century-inspired design makes these Independent Network uPVC flush-fit windows ideal for those making home improvements in conservation areas, where authentic looks are all-important.

Plus, the right choice of hardware, such as monkey-tail handles, can really add to the heritage look and feel you’re looking for – ask your Independent Network installer for details.

In short, our FlushSash uPVC windows have the heritage looks you want, with all the modern benefits you need. 

Flush Fitting

Where contemporary chamfered and sculptured casement styles are designed to add contour and detail to your windows, FlushSash uPVC windows, as the name suggests, sits flush within the frame, offering traditional, understated elegance.

Inside and out

These traditionally styled uPVC windows are easily tailored to the design of your home, being available in a wide range of colour and woodgrain finishes. There’s even the option to have different finishes on each side of the frame – perfect for complementing your interior design scheme.

Contemporary Twist

On the flip side, FlushSash windows can also be a great addition to a contemporary property, when manufactured in on-trend colours such as grey or black.
