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.

Our products are designed for the home, our windows will transform your property in ways you couldn’t imagine. We’re passionate about manufacturing truly authentic designs of traditional sash windows.
Masterframe sash windows come with a wide variety of choice in colour, style, furniture and design. At the end of the day, it’s your home, so ultimately your personal choice. We simply pledge to provide you with the widest range of options available and as much or as little advice so that you are delighted with your final decision.
If you love the look of real wood then our timber alternative sash windows with a traditional grained wood effect are an ideal choice. The best news is that they are low maintenance, requiring only routine cleaning to keep them looking their best.
We understand that deciding the right style 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.
Sash windows were first installed nearly 400 years ago and 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.
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.
