uPVC Sash Windows Eltham

Enhance your home with our beautiful uPVC sash windows, installed to properties in Eltham and the surrounding areas. We here at Sutton Windows are proud installers of Masterframe’s range of sliding sash windows – benefit from a high quality product that is sure to add style to your home. 

The sliding sash design has been around for decades and has been installed in Eltham homes for just as long. Previously made from timber, these windows looked incredible but offered poor performance levels. Our profiles are made from modern uPVC, and because of this, we have managed to bridge this issue. 

From installation, your home will be warmer, more secure and free of any damp or mould issues. By using advanced double glazing, our windows work as a thermal barrier. As well as this, they come in a range of bright and neutral colours to ensure we have something for everyone.

Why uPVC Sash Windows?

uPVC sash windows are a top tier product for many reasons – but mostly because they offer style and performance in one. While traditional timber variants added authentic allure to any Eltham home they were installed in, they also led to poor performance and costly upkeep. Our uPVC designs contain all the traditional design features, without any of the outdated setbacks!

Once installed, your new sliding sash window will add true value to your home. uPVC is highly customisable, and whatever shade you select will not ever fade. Because of this, your new addition will be virtually maintenance-free. What’s more, uPVC is weather resistant and does not warp or flake!

uPVC Sash Window Styles

To ensure that we have something for all our valued customers, we offer Masterframe’s incredible Bygone collection. This consists of three main sliding sash window designs that can be installed in homes in Eltham quickly and efficiently. Whichever style you choose, you will benefit from high performance as standard.


The Symphony is the cherry on top of the cake. Benefit from the highest levels of performance, and true period style. Designed to be a complete replica of traditional timber designs, this window profile is perfect for heritage and period properties. You can even install it to conservation homes that require timber replica windows. Including steel reinforced sashes, making it a great addition to all properties.


If you are looking for something a little more versatile, you may prefer the Harmony. Still featuring authentic appeal, the Harmony is slightly more customisable. This makes it a great match for modern and traditional homes alike. Benefit from affordable price points to meet all budgets.


Invest in a window that excels in all areas with the Melody sliding sash window. Extremely cost efficient, this window will suit all homes in Eltham. Featuring robust double glazing and a modern uPVC frame, this window offers style and functionality at a value for money price.
