How Long Does Double Glazing Last?

Significant technological advancements in windows manufacturing have occurred in recent years, leading to the development of updated and longer-lasting products. 

For instance, modern double glazed windows ensure vastly improved thermal performance and durability.

However, the longevity of your windows depends on various factors, including environmental conditions, quality of the windows, quality of installation, and maintenance practices.

Therefore, it’s essential to consider these factors when assessing the lifespan of your double glazing. Proper care and maintenance can significantly extend the life of your windows, ensuring optimal performance and durability over time.

Here at Bergson & Eaton, we provide high-quality double glazing for homeowners in Aylesbury and beyond, along with professional service and top-notch installation. 

In this article, we’ll delve deeper into the lifespan of double glazing windows and its long-term benefits, so that you can make the right choice with your next window installation.

What is Double Glazing? 

One of the most compelling reasons to invest in quality windows lies in their intense energy efficiency, particularly with double glazing. But what is Double glazing really? 

Double glazing involves installing two panes of glass separated by a layer of inert gas, typically argon or krypton. This design significantly enhances insulation, reducing heat transfer and minimising energy consumption for heating and cooling. Consequently, homes equipped with double glazing often command higher property values.

How Effective is Double Glazing?

The durability of your double-glazed windows primarily depends on the quality of the sealed unit. While the frame’s quality and material are still significant factors, a failure in the sealed unit could compromise the window’s insulation properties entirely. Most manufacturers provide guarantees and warranties for the double-glazed unit. 

Generally, a minimum lifespan of 20 years is assured for double-glazed units, with expectations of 30 years or more, particularly when installed in sheltered locations. Therefore, ensuring the integrity of the sealed unit is crucial for maximising the longevity and performance of your double-glazed windows.

What Factors Affect its Longevity?

Several factors can significantly impact the lifespan of double-glazed windows:

• Location: Whether your home is in a covered or exposed position plays a crucial role. Coastal properties, for instance, subject windows to corrosive saltwater, leading to a shorter lifespan compared to windows in less exposed environments like the countryside.

• Quality of Manufacture: The quality of double glazing we provide is superior and meets the highest standards. Our skilled craftsmen tend to have longer lifespans compared to those produced with cost-cutting measures. Our high-quality materials and precise construction contribute to enhanced durability.

• Quality of Installation: Proper installation by a professional and experienced installer is essential for maximising the lifespan of your windows. Correct fitting ensures that the window sits snugly in the opening without gaps and is completely sealed. Poorly installed windows may allow water ingress between the brickwork and the frame, leading to damp issues and potential rot, especially in timber frames.
