Despiting looking like a traditional timber window, our sash variety isn’t affected by the same high-maintenance issues. These windows won’t crack, twist, rot, fade, warp after exposure to the changeable Wiltshire weather. All the homeowner needs to do to maintain the appearance of these windows is give them an occasional wipe with a damp cloth. All of our double glazing products, including our uPVC Sash Windows, are accompanied with a 10-year guarantee of quality. This covers the workmanship and the parts, so you can choose your window with the confidence that it lasts.
