If you’re looking into the benefits of double glazed windows you’re probably attracted to them because of their low maintenance, thermal efficiency and security. But with uPVC windows and doors being relatively new to Australia, you are wondering how they stand up to their tried and tested wooden/aluminium competitors. You know how long wooden windows can last (with correct maintenance), or aluminium, but how long do uPVC doors and windows last?

There isn’t a simple answer, typically the lifetime of double glazing is around 20 years, however with any product the quality has a major part to play, meaning that this can vary anywhere between 10 – 35 years depending on the quality of the materials, installation and the placement of the windows/doors.

What Factors Influence How Long uPVC Windows And Doors Last?

Okay, let’s start with the basic component, the uPVC. uPVC stands for unplasticised polyvinyl chloride. Every uPVC door and window manufacturer has their own unique formula for making their products. For example, one supplier may use a different combination of frame, glass and hardware.

The quality of the raw materials used can make the difference between a low-grade or a high-grade uPVC double glazed window or door. uPVC windows and doors are available in a variety of colours, depending on the ratio of chemical components used will determine the window’s ability to maintain the frame colour for example. Windows that are excellent at thermal efficiency and soundproofing are not going to be very practical for a home if they aren’t visually appealing, after losing their colour quickly.

So when deciding upon uPVC as your window material of choice, make sure that you choose a supplier that produces high-quality uPVC, that will prove to be long-lasting and maintain the same appearance for decades to come.

uPVC & Double Glazing – What Matters

uPVC is the material that is used to hold two panes of glass together, creating a uPVC double glazed window. Within these two panes of glass is a gas that is used to ensure optimal energy efficiency, so the compound that is used to seal these gaps is also crucial in ensuring that water/moisture is kept from the inner workings of the window, further prolonging the life expectancy of the window. Using a quality polymer compound will ensure your double glazed windows last for longer than those poorly produced alternatives.

Importance Of Installation For Double Glazing

So you’ve ensured that you have sourced top quality uPVC, with exceptional manufacturing and have the perfect product good to go. Don’t fall at the final hurdle. Expert installation plays a key part toward how long your uPVC windows and doors will last. The best product in the world will not be worthwhile without correct sizing, fitting and sealing, only possible using professional window installers with the knowledge and experience to ensure that you get the longest possible lifespan from your uPVC double glazed windows and doors.
