The technology behind uPVC windows is relatively simple, but incredibly effective. The frames are made from sections of uPVC, which are then filled with a special gas that helps to improve their thermal efficiency. The windows are then sealed to ensure that this gas does not escape, and to prevent any draughts from entering the home.
One of the main benefits of uPVC windows is their excellent energy efficiency as a result of this process. In addition, because uPVC is a non-conductive material, it does not transfer heat, helping to keep your home warmer in the winter and cooler in the summer.
