When it comes to the lifespan of double-glazing units in windows and doors, it’s akin to asking about the length of a piece of string. Several factors come into play, including the glass quality, exposure to varying weather conditions, and installation quality.
How long does double glazing actually last?
On average, double-glazed windows have a lifespan of approximately 15-20 years. However, it’s worth noting that companies often provide a guarantee for the gas-filled glazing units for a shorter duration, typically between 5 to 10 years.
Most double-glazed windows consist of two glass panes with a gas-filled space between them. Over time, this gas gradually evaporates, resulting in reduced effectiveness and poor insulation qualities. This deterioration can occur within 10-15 years.
Ensuring the proper functionality of your double glazing is crucial to prevent heat loss and save on energy bills. By maintaining your windows’ insulation properties, you can optimise energy efficiency and maximise cost savings.
The longevity of a double-glazing unit exceeding 30 years can vary significantly depending on the location. While windows are engineered to endure harsh weather conditions, areas that are particularly exposed or open may face more challenges. This consideration sometimes leads individuals to contemplate the adoption of triple glazing, although such measures are seldom necessary in the United Kingdom.
Instead, the recommended approach is to replace any double glazing that has become compromised or ineffective. By addressing failed units promptly, you can ensure the continued performance and energy efficiency of your windows.
Feeling cold air around the perimeter seal of your window signifies that the glass unit is no longer effective. It’s time to either replace the windows or retrofit the double-glazing units with new ones (double or triple-glazed) to restore insulation and prevent heat loss.
