What is the Life Expectancy of Double Glazing?

How long does double glazing last?

Double glazing is becoming increasingly popular throughout the UK due to its energy efficiency, noise reduction qualities, and security benefits. But how long does double glazing last? We take a look at what you can expect from your double glazing installation and explore how to get the most out of your windows.

Double glazed windows are designed to offer improved insulation, security, and sound reduction for your home. They are generally made from two panes of glass, with an airtight gap between the two. The average lifespan of double glazing depends on several factors, including the quality of the materials used and the level of maintenance. 

A double glazed window produced with high-quality materials and properly installed can be expected to last around 15-20 years, but this may vary according to the environment and usage. Keeping the windows in good condition by regularly cleaning and carrying out necessary maintenance will maximise the lifespan of your double glazed windows.

What factors affect the lifespan of double glazing?

Several factors can affect how long double glazing lasts, and it’s important to consider these when making your decision. These include: 

• Quality of Materials: The quality of the material used for double glazing has a direct impact on its lifespan. Look for double glazing units that are manufactured with high-grade materials, as this will result in a longer service life.

• Level of Maintenance: Regularly cleaning and maintaining your windows is important to keep them in top condition. This will prevent damage and extend the lifespan of your double glazing.

• Exposure to the Elements: Proximity to the sea, exposure to extreme temperatures, or location in a windy area can all have an effect on the longevity of your double glazing. To protect the windows, consider installing covers such as storm shutters or storm doors.

What are the top signs that it's time to replace your windows?

If your double glazing isn’t performing as well as it once was, it may be time for a replacement. Here are some of the most common signs that your old windows need replacing: 

• Water Leaks: If you see any condensation, water buildup, or pooling between the panes of your windows, then it’s likely time for a new set.

• Drafts: If you can feel a draft from your windows, then chances are they need replacing. Air leakage not only affects your comfort but also increases your energy bills.

• Difficulty Opening/Closing: If it’s becoming difficult to open or close your windows, then it’s time to repair or replace them.

• Unusual Noises: If you can hear strange noises coming from your windows, then it could be a sign that they’re needing repairs or a full replacement.

How does wear and tear affects double glazing units?

Even if you keep on top of maintenance, double glazing units will eventually wear out due to age and normal usage. Over time, the materials used in double glazing can degrade and become less effective. This could cause problems such as water leaks, drafts, or difficulty opening and closing your windows. 

To prevent wear and tear, make sure to regularly check your windows for any signs of deterioration and carry out necessary maintenance or repairs. You should also replace any single glazed windows in your home with double glazed units to ensure maximum efficiency and longevity.

How to choose the best double glazed windows

Choosing the right double glazing for your home is essential for ensuring that it stands the test of time. When selecting a supplier, make sure to ask about the materials and installation process used, as well as any warranties offered. It’s also worth researching the different types of double glazing available and considering the environmental impact of your choice. 

You should also ask your supplier to give you a comprehensive quote so that you know exactly what you’re getting for your money. And don’t forget to ask about any available discounts or incentives. 

Ultimately, the best double glazing windows are the ones that meet your individual needs and budget. Taking the time to research your options and choose a reliable supplier will help you to get the most out of your double glazing installation.
