As well as being more cost-effective than other window materials, uPVC (unplasticised polyvinyl chloride) requires almost no maintenance. There are also plenty of options to choose from.

We offer a wide range of bespoke double-glazed uPVC windows in a range of different window styles. From uPVC casement windows to uPVC sliding sash windows, there’s a style to suit every property. Whether you’re looking for white or coloured uPVC windows, you’ll find something in our huge range to suit your taste.

Classic hardwood windows can make all the difference to your home’s overall appearance. When it comes to window materials, there’s often a compromise between aesthetics and practicality. Not so with hardwood windows. This durable material is both energy-efficient and attractive.

Choosing hardwood replacement windows for traditional properties helps to maintain a classic look and feel, while still enjoying the benefits of a modern finish. If maintaining a period look is important to you, you’ll find our wooden windows are available in a variety of styles, including flush sash, flush casement and tilt and turn windows. Choose from golden oak, larch, pine and more.

Double-Glazed Windows Keep You Warm

Choosing to upgrade from single to double-glazed windows is a smart decision. The additional two panes of glass will dramatically reduce heat loss. The cost of your replacement windows will pay for themselves in no time with the money you save on your heating bill!

When it comes to choosing the right double-glazed window, the frame material is a matter of taste. It doesn’t matter if you opt for coloured uPVC windows or hardwood, you’ll still enjoy the same level of thermal protection and security from your new double-glazed panes.

The frame and type of glass you go with will affect the cost of your replacement windows, but we’re more than happy to work with you to find something that suits your needs and tastes as well as your budget.

Our products are all locally made and manufactured to the highest standards. Secure and weatherproof, they make an aesthetically pleasing addition to any home. As if that’s not enough, they’ll also help you reduce your energy bills and make short work of noise pollution too! Choose new double-glazed windows today, you won’t be disappointed.
