As a sash window specialist, we do not manufacture any other products. We believe this not only makes us an authority on the subject, but also gives us a special enthusiasm and appreciation for sash windows that drives us forward in terms of product development and manufacturing the best timber alternative sash window product available. 


Here's a short video about The Bygone Collection and some of the choices you have.

The Bygone Collection of Quality supplied windows

Why Bygone? This video explains.


Bygone sash windows come in a wide variety of materials, colours and finishes. At the end of the day it’s your home, so ultimately it's your choice! We simply pledge to provide you with the widest choice available and as much or as little advice so that you're delighted with your final decision, whichever it may be. We genuinely don’t mind which style you select because we consider ourselves 'material neutral'.

If you love real wood then our Traditional wooden sash or Spring balanced sash are ideal for you. However if you wish for real sash windows with a grained wooden surface that's easy to keep clean and never requires painting, then our Symphony, Harmony or Melody sash will be perfect.

We understand that deciding the right style, material and design of your windows will take time, but finding a solution that retains the special character of your home is well worth the effort. You’ve invested a substantial sum buying your own property so any improvements must enhance it, make you feel warm and secure inside it, and be long-lasting. Here are some answers to the frequently asked questions.

We've been making sash windows for more than 25 years and because we're material neutral you'll get the same quality and attention to detail, regardless of which material you choose.

The two windows below illustrate the point.

Both of the windows below are from our Bygone range. Each has the same furniture, but one is timber the other is a uPVC wood alternative... can you tell which is which? 

Timber vs uPVC Sash Windows

We try especially hard to recreate the aesthetics of traditional timber windows

Sash windows were first installed nearly 400 years ago and we've a section on the history of sash windows here. They were originally propped open with wedges or timber dowels until someone decided to open them with rope, like a drawbridge.

Glass has played an important part in the development of sash windows, being more expensive than gold when it was first used. The challenge has been to make larger panes, hence the small diamond shaped lead lights leading to Georgian squares, and in turn on to larger Victorian sheet glass hung on chains because the weight had increased considerably.

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.

People you can trust

You’re in good hands, we've specially selected installation partners across the UK who are very experienced in fitting sash windows. Those joining us with limited experience attend our survey and installation training before selling or installing our windows.

A number of our production team have been employed for more than 20 years and a few of our older hands have been associated with sash windows since the 1970s.

Up for "close inspection"

If you wish to visit our production plant in Essex you are most welcome. We'll be delighted to show you the window finishes and colours, give you a full tour of the plant and answer any questions you might have, helping you rest easy about the quality of your new windows.

If you're not able to visit us you'll be pleased to know that we voluntarily ask (and pay for) the British Board of Agreement, ISO and the Police (through 'SBD' their preferred standards scheme), to inspect our factory and check our standards and processes as independent external review bodies.

We are also members of the Glass and Glazing Federation and The Glazing Ombudsman scheme; again being bound by their regulations voluntarily, so that you can feel confident in the knowledge that you can obtain independent arbitration should you be unhappy with any aspect of our work.

Years of improvements.

If like us you believe the sash window to be 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.

each had the same furniture and at first we couldn't see the differences, so we went for the windows that won't need painting!"
