Replacements for Timber Sash Windows

Homeowners looking for replacement sash windows are often experiencing the same problems. Draughty frames, cold single glazing, rattling panes and stiff sashes – old timber sash windows are beautiful but in many cases unusable. But how to upgrade without losing the elegance and charm of historic and bespoke sash windows?

In every case, we recommend designing new sash windows bespoke for your home, maintaining the period style where possible. It’s also possible to upgrade to double glazing without losing any of the vintage charm – as long as you choose a replacement sash window model that has been designed with slim glazing in mind. Some people say that nothing beats timber sash window frames for authenticity – we say they can’t have tried the Rose Collection sash window replacements! These premium replacement uPVC sash windows are designed to look exactly like traditional timber sliding sash windows – down to the last detail.

The natural beauty of timber with the modern comfort we expect

Timber is a fantastic, stylish material – but timber windows are very often expensive to install and maintain, requiring a lot of upkeep to protect them from the elements. Timber is more likely to rot over time, meaning it's less durable than uPVC, which is manufactured using the latest modern technologies. That’s the beauty of the Rose Collection – premium quality uPVC windows that deliver all the charm and vintage detailing of timber originals, with none of the hassle, along with exceptional thermal efficiency and all-round performance.

Whether you choose Heritage Rose or Ultimate Rose, you can be confident that your replacement sash windows offer all the benefits of timber and more, with none of the drawbacks.
