Well-fitted double glazed units typically last 20 to 30 years, depending on the materials used, weather exposure, and the quality of the installation process. You'll need to balance these considerations against cost before arranging an installation.

uPVC frames are long-lasting and low-maintenance, while aluminium and timber may need occasional care. You may find uPVC windows and uPVC doors are a sensible, practical choice, but perhaps lack the luxurious style you'll get with timber or aluminium.
