We're open, although not quite as usual.
As the world slowly returns to normal (or the new normal), we and many of our Approved Installers have re-opened. To keep things safe we’ve reduced our manufacturing capacity, and Approved Installers are following strict guidelines for working in people’s homes. Our team have been on hand, working from home, throughout the lockdown to give you the best advice regarding your sash window project. That continues. So no matter what stage you are at with your home improvement project, from planning to ordering, we can help. In the meantime, please continue to #StaySafe.

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 sliding sash 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.
