Authentic Design

Sliding sash windows are fitted with multiple design features to add to the characteristics of the window. The combination of the ovolo frame and the run-through sash horns will help to add a timeless feel to homes. Each of our uPVC sliding sash windows is tailored to match the dimensions of your next project.

The sliding sash windows that we offer come in a gorgeous woodgrain effect to help keep their authenticity. Whether you are looking for a heritage feel or something more modern, you can design your windows to meet your needs. A wide range of hardware is available in a selection of colours to complement the sliding sash windows.

Enhanced Thermal Performance

The uPVC frame used for our sliding sash windows is multi-chambered, making them very energy efficient. The chambered profile acts as a thermal barrier helping to prevent possible heat loss. Our sliding sash windows come with 24mm double glazed units as standard that will help to retain the property’s natural heat, regulating the temperature throughout the year.

The combination of the insulating frame and double glazing can achieve a ‘B’ energy rating and a U-value of 1.6W/m2K. If you choose to upgrade to have argon gas, your windows can achieve an ‘A’ energy rating and a U-value as low as 1.4W/m2K. Homeowners can improve their energy savings and lower their monthly bills.

Several properties in our windows, including weather bars, hold excellent resistance against the elements.

Homeowners can have peace of mind that our sliding sash windows will help prevent unwelcome draughts and water ingress from entering their homes.
