uPVC Framework

We use a market-leading uPVC profile for our sliding sash windows. Timber was originally used for this window design. However, this comes with a lot of issues, especially when it comes to the weather. By using uPVC, we can imitate a timber profile and secure your Middlesbrough home from adverse weather conditions. uPVC sliding sash windows are also very insulating and can create a thermal barrier between your home and its surroundings.

uPVC is very flexible, meaning that our sliding sash windows can be tailored to complement your Middlesbrough home. We have various colours available for you to choose from to enhance your property’s interior and exterior. Woodgrain effects are available for Middlesbrough homeowners that want that timber look. There are multiple hardware accessories to choose from to complement the frame and complete the final look of your windows.

Thermal Performance

Double glazing is fitted within our sliding sash windows to improve the energy efficiency of your Middlesbrough home. The glazing works by trapping warm air bubbles and keeping them within your property. Our sliding sash windows can achieve a Windows Energy Rating of B and a U-value as low as 1.6W/m2K. With the inclusion of argon gas, our windows will be able to achieve an A energy rating and a U-value as low as 1.4W/m2K.

The uPVC framework of our sliding sash windows is equipped with multiple chambers that use air as an insulator to stop heat from escaping. This is a fantastic way to help keep your Middlesbrough home as naturally warm as possible and prevent the entrance of draughts. The appropriate temperature regulation allows you to keep it at the ideal level at all times. As you rely less on using your heating, you can reduce your carbon footprint and save money on your bills.
