focus on: Clare Higgins, head of design at Rehau, reveals how and when to replace existing PVCu windows in a sustainable way
Rehau’s range of PVCu windows offer durability, longevity and can be recycled at the end of their useful life; used to make the next generation of PVCu windows
How long should PVCu windows last?
Our modern frames are manufactured to a high standard and can last up to 40 years, exceeding British Standards, which recommend that sealed units (the whole window) have a service life of at least 20 years. PVCu is a durable, long-lasting material; the frame itself won’t degrade over that time, but the surface of the profile might deteriorate.
Typically, the other components of the window, such as the glazing itself, the beading or the hardware, will fail before a modern PVCu frame. Handles are specific to the manufacturer, so could last anywhere between 10-25 years – it’s worth checking if the company offers a robust guarantee for these.
