UPVC windows are one of the most popular window frame materials in Scottish homes.
It has been in homes for decades first becoming popular in the late 1900s, taking over other common frame materials such as timber and aluminium.
But how long do they last?
Read on to find out how long uPVC windows lasts.
What is UPVC?
UPVC stands for unplasticized polyvinyl chloride. It is a lightweight plastic that is often used as a frame material in many homes in Scotland.
It was originally manufactured back in 1935 but it wasn’t introduced into the UK until the late 1970s.
By the 1980s, uPVC’s popularity began to take off and it became the most popular window frame material bought during this time.
Today, it is still extremely common in Scotland with most households having it.
Why is UPVC so Popular?
The popularity of uPVC is due to a variety of reasons.
Firstly, it is a cheaper alternative to other frame materials such as timber and aluminium while being just as efficient.
It requires little to no maintenance and therefore is an easy choice for those who don’t have time for the upkeep of other frame materials.
UPVC is also available in various colours and finishes as well as window styles to fit different homes.
How Long Does UPVC Last?
UPVC typically lasts up to 20 years but this can vary between 15-35 years.
The lifespan will depend on different factors such as:
Quality
The quality of the uPVC can determine how long it is going to last. The better the quality the longer it will last you therefore it is important to make sure you are purchasing high-quality uPVC frames.
High-quality uPVC resists fading, cracking and damage. This is even when it has been exposed for a long time to sunlight, varying temperatures and moisture.
Environment
Depending on where you live can affect the lifespan of uPVC (as well as most other frame types). If you experience harsh weather conditions, high UV radiation or high levels of pollution, this can affect the lifespan of your frames.
Other environmental factors can include exposure to saltwater from living by the coast as this can cause your frames to deteriorate faster.
There isn’t much you can do in terms of controlling the environment’s effects on the lifespan of your uPVC windows. Just keep in mind though that they may need to be replaced quicker due to your location.
Care and Maintenance
If you look after your UPVC windows well and keep up with their little maintenance then they should last you a long time.
To maintain your windows you should clean the frames using just a damp cloth. In some cases, you may need a specialist cleaning solution. Don’t use any harsh cleaners as this can damage the frame.
As for the glass, a simple glass cleaner or soap and water will do.
Other maintenance on window units includes maintaining its hardware and hinges.
Installation
Choosing the right installer also factors in how long your uPVC will last.
Incorrect or poor installation can lead to a reduction in energy efficiency and lifespan as well as leaks and more.
