How long do uPVC windows last?
UPVC is the most popular choice for double glazed windows in the UK because they are low maintenance, energy-efficient and secure.
UPVC is a durable material but white uPVC can stain if it's not cleaned properly. Cheap uPVC is a false investment as it can warp and discolour over time and won't last as long as a reputable brand of double glazing.
To invest a little more, in the beginning, can make the difference of an extra 10-15 years.
UPVC double glazed windows will last from 20-25 years.
