About Masterframe

We admit we’re a little obsessed!

Loving sash windows as we do, we hope that you’ll appreciate the time that’s been devoted to ensuring our styles are as authentic as possible.

We steer clear of making casements, doors or patios. We found our niche and decided to stick to what we do best, making one product and one product only – stunning sash windows.


Masterframe founder Alan Burgess pioneered a new direction for the design after helping create the UK’s first dedicated PVC-U box sash in 1984. Shortly afterwards he set about creating a market for PVC-U sash windows.


We tend to work on a wholesale basis, supplying other companies with own brand sash windows and installers with bespoke solutions.


Dedicated to retaining the elegant proportions of traditional windows through continuous innovation, creative flair and passion, you can be confident we set extremely high standards with excellent craftsmanship and attention to detail.

You’ll find we’re not cheap. Indeed we’d go so far as to say we’re considerably more expensive than other sash window producers. That’s because we include more, do more and taking like for like, you can expect us to be excellent value for money.


You set the standards with your own specification, the benchmark you expect your new windows to attain, using the components you require and that you believe are right for your project. We will help you understand what is important and set out to exceed all expectations.

As conservation officers across the UK have found, if you decide to invest in our products, your perceptions of PVC-U will probably change for good.
