How Long Does Double Glazing Last?

A question often asked within the home improvement industry is how long double glazing lasts.

How Long do uPVC Windows Last?

The number of years uPVC windows last can vary depending on how well they’re made, installation and the aftercare from the homeowner. uPVC is a lightweight plastic used specifically for construction, and the windows made from this should last somewhere between 20-35 years.

All windows at Your Price are A rated, meaning you get a guarantee for their longevity.

How Long do uPVC Doors Last?

The same concept of good look after and high quality installation applies to uPVC doors. If this is done, then they can last up to 35 years. uPVC is a great material for doors as it does not fade, and the door can be easily cleaned to regain its original look.

Depending on the quality of uPVC you use, it can affect the longevity positively or negatively. If you choose low grade uPVC over high grade uPVC, your double glazed product will not last as long.

Factors Affecting the Lifespan of Double Glazed Products


The location of your property is a big factor when considering the lifespan of your double glazing products. If you are situated in an area with harsh weather conditions such as strong winds, rain and snowfall, your products will have a shorter lifespan. Moreover, if you are situated in coastal areas, their life span will be reduced due to acidic saltwater.

Quality of Production
