In the UK, tens of millions of double glazed windows have been in place before 2002. These units, after all, are more efficient than single-pane windows. They are better in reducing heat gains and losses that occur through windows.

They cost more, but programs like the new Green Energy Grant can make them more affordable. With this scheme, you can finally upgrade to double glazing windows. Combined with other energy-saving improvements, you may save up to £300 a year on your bills.

How Long Do Double Glazed Units Last?

Researchers found that double glazed windows have a median payback period of 8.75 years. Throughout this period alone, these units have shown to reduce energy consumption by 72.9%.

Properly installed and placed, however, double glazed units can last for 25 years up to 35 years. Plus, these new windows alone can already save you up to £175 a year!

Window Placement Can Affect Double Glazed Lifetime

In the UK, south-facing windows receive the highest amount of sunlight and heat. In a place where unsettled weather conditions are typical, these windows are must-haves. It’s also why south-facing houses cost more than east- or west-facing homes.

However, south-facing windows also experience the most temperature gradients. These fluctuations can affect the seals and adhesives, making them fail earlier. As such, double glazed units that face south have a shorter life span, the average of which is 12 years.

Higher-Quality Materials Translate to Longer Lasting Windows

Between the two panes of double glazed units is a gas that should be less conductive than the gases in the air. Argon gas boasts this characteristic. Hence, it’s the most common gas used in filling up double pane windows.

To make sure that the gas stays inside the panes, though, there must be a perimeter seal. This is the part that protects and encloses the air gap between the windows.

Moreover, the perimeter seal contains tiny silicone desiccant beads. These small particles help absorb moisture to keep the entire enclosure dry.

This is why it’s crucial to choose window installers who use only top-notch materials. This way, you can be sure that your windows won’t be prone to the effects of excessive moisture. By keeping excess water at bay, your double glazed units will last longer.
