Masterframe, multi-award winning manufacturers of The Bygone Sash Window Collection are the only true "specialist" manufacturer in the country.  Bygone Collection sash windows are the perfect timber alternative and suitable for installation in conservation areas. To find your nearest installer of our Bygone Collection sash windows please visit www.bygonecollection.co.uk or to buy our exclusive trade ranges direct www.masterframe.co.uk. Each year we must stay ahead of the competition, so each year we develop new and exciting features like Timberweld®, Georgi-clips® and bespoke GRP sections. Dedicated to retaining the elegant proportions through continuous innovation, creative flair, passion and design, 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, but there are good reasons for that, not least because we include far more. We’re happy to explain differences, the standards we set ourselves, the attention to detail we insist upon and gladly provide a wealth of testimonials from clients who trust us with their orders. You decide the specification which suits your needs best, the benchmark you expect new windows to attain, using only the features that you believe are right for your project. Our job is to help you understand what the important features are and the choices you have, like:

• Timberweld® technology for perfectly sealed corners
• A rated for energy efficiency
• Secured by Design
• Exclusive profiles

We would be delighted to help you further with your project.
