The UK’s Most Advanced Sash Window Range

You have the choice of three different Bygone collections to consider for your home. Whilst each has the same attention to detail, build quality and exclusive Bygone locks and handles, they offer you an array of choice to ensure your new windows fit your home and budget!

The Symphony Window

Our premier Bygone sash window is probably the best PVC-U sash window available in the market place. The Bygone Symphony succeeds when “only the very best” will do. As you might expect, this range has virtually every optional extra fitted as standard.

Wood grain textured acrylic foil on all profiles with every corner has a traditional, vertical and sealed, “butt jointed” construction, providing the perfect appearance.

The Harmony Window

With identical frame and sash profiles to those found on our premier Symphony product, including the beautiful wood grained, textured acrylic foil on all profiles, Harmony also has a deep bottom rail, continuous run through horns and exclusive Timberweld® construction.

The Melody Window

Identical frame and sash profiles to those found on the Symphony and Harmony product, including the beautiful wood-grained, textured acrylic foil on all profiles. Every deep bottom rail and continuous run-through horn has traditional butt joints.

Colour Range

Our sash windows are all available to you in a choice of colours to suit your own individual décor and we will colour match to all leading brand paint supplier palettes.


Our colour configurator features our most popular colours and is designed to help you to see how sash windows look in-situ in a colour you might be considering. You can experiment with a host of colours and we hope that this will help you greatly in making your final selection.

Traditional Appearance

Our challenge today is to retain the traditional appearance of sash windows supplied centuries ago with today’s strict building regulations, the demands of conservation and planning authorities, and the natural desire for exceptional energy efficiency, enhanced security and ease of use.

You’ll be pleased to learn that we’ve found a way to satisfy these requirements with beautiful, authentic-looking windows you will be proud of.

If you also believe that the sash window is the finest design in history, you’ll appreciate the time we have invested to make certain our products are as authentic as possible. Combining the elegance of sash window design with modern manufacturing techniques creates replacement windows with character that fit your home perfectly.
