How often should you change your windows?

A few times a year we are reminded how often we should be changing household items. Experts say that towels have a useful life of 2 years, with sheets and pillows having the same lifespan. These are items that are fairly easy to change, yet some of us have had the same towel for far longer than we’d like to admit. What about the items that are more tricky to change, such as windows?


How long do windows last?

uPVC windows have an estimated useful life of around 25 years, with aluminium windows lasting upwards of 30 years. However, windows that were produced even 20 years can’t rival today’s offering. Besides Window Energy Ratings (WER), U-Value is a commonly used measure of how energy efficient your windows are. It measures how easily heat can pass through a material. The lower the value, the better an object can stop heat from escaping the home.

Building Regulations in the early 2000s required windows and doors to have a U-Value of 3.1 1.6 W/m²K or below, as such, windows were manufactured to meet this standard. Fast forward to today and windows have seen dramatic developments over the past 20 years, which have been accounted for in the country’s Building Regulations. They now specify that windows should be made to achieve a U-Value of 1.6 W/m²K.
