Residence9 Windows

Diamond Windows Droitwich are leading suppliers of timber alternative windows in Worcestershire.

Our Flush casement windows are made from high quality uPVC that looks identical to timber windows, giving you a classic look with modern glass and insulation technology.

Nineteenth century design, 21st century technology

Nineteenth century flush sash timber windows look timeless and sleek. Our uPVC alternatives to timber windows replicate this beautiful look but are made from luxury uPVC and feature a nine-chamber system that harnesses all the benefits of 21st century technology.

Real timber look and feel

If your property has windows or doors that were designed and installed in the 19th century, our Flush casement windows are the perfect option to retain the original charm of your property, but to bring it forwards into the 21st century at the same time. We have a wide range of styles, ensuring you’re able to find the right choice for your home. Our windows are the ideal swap for traditional 100mm timber windows.

One of the main advantages of our Flush 100 casement uPVC timber alternative windows is that whilst they look and feel like the real thing, they don’t require the same level of upkeep as traditional timber windows. They won’t rot or require painting or staining to keep them looking brand new – the frames can easily be wiped down to keep them looking fresh and beautiful.

Flush 'Alternative to Timber' windows from Diamond Windows Droitwich are A Energy Rated as standard.

If you have a modern property and want to add some character to it, these alternative to timber windows are ideal. The casement fitting and internal decorative finish offer unrivalled style and functionality.

Wide Range of Finishes and Styles

We offer many different types of timber alternative windows made to almost any specified height and width. You can choose from a wide range of woodgrain colours and effects, as well as handles and sashes, ensuring you find the right solution for your home.

Whether you need simple replacements for your upstairs rooms or a more ornate solution for your bay living room, Diamond Windows Droitwich has a wide range of aluminium windows for sale, ensuring we have something to suit your style.

10 Year Guarantee

All of our double and triple glazed timber alternative windows are easy to maintain and keep looking like new, partly due to their durability and longevity. We’re so confident in our windows that we offer a ten-year insurance-backed guarantee as standard.

Enhanced Glazing Options

We’re also proud to be able to say that our high-tech glass technology means we can make the most of increased energy efficiency, resulting in higher levels of insulation. The invisible PLANITHERM coating captures daylight energy and reflects it inwards to warm your home, all whilst reducing the risk of condensation and without creating a noticeable tint or haze.

Diamond Windows Droitwich also installs enhanced glazing and triple glazed uPVC windows which reduce noise pollution. The extra pane of glass not only helps with increased thermal efficiency, but it can also make your home more secure.
