Features & Benefits

With our sliding sash windows, you’ll be able to keep the winter winds at bay with style. A high performance, multi-chambered profile works in harmony with contemporary weatherseals to keep the elements out of your home. With this in place, you’ll be able to enjoy a home that remains warm and comfortable throughout the year.

Due to their ‘A’ rated standard of thermal efficiency, our sliding sash windows could also help you to save money on your heating costs. With an enhanced level of heat retention integrated into your home, you could find yourself relying less on your central heating throughout the year. In turn, this could result in a lower heating cost and carbon footprint.

To ensure you find the ideal sliding sash window design for your home, we offer three distinct collections to choose from. The Charisma, Heritage, and Ultimate ranges are designed to offer different and stand out approaches to the original sliding sash window design. From echoing the traditional charm through to offering a modern spin, we’ll have something to suit you.

Choosing from one of these ranges will enable you to get a window installed into your home that not only serves as an addition to your property, it also serves as an extension of your taste. With a traditional approach inherent to these designs, you can rest assured that you’ll be able to capture the core essence of the original sliding sash window without any compromises.

To avoid any outdated or obsolete problems, all of our sliding sash windows are designed in accordance with the demands and expectations of the modern age. With this in mind, they are able to offer you leading standards of thermal-efficiency, security, durability, performance, appearance, and functionality.

A demonstration of this can be seen in the modern pre-tensioned balances that are guaranteed not to stick, with inward tilting sashes allowing you to clean the outside of the windows from the inside. They also bypass a heavy sash, usually associated with the original design, to aid in a smooth and easy operation every time.
