How Long Do Double Pane Windows Last?
How Long Do Double Pane Windows Last?
The lifespan of double pane windows can vary greatly, depending on several factors such as the quality of manufacture, environmental conditions, and maintenance practices. Understanding these factors is crucial for homeowners planning to install or replace their windows.
Introduction to Double Pane Windows
Double pane windows, also known as double glazing, consist of two panes of glass separated by a gap, sealed with an inert gas to help insulate and prevent heat loss. These windows are popular due to their energy efficiency and ability to reduce noise pollution.
Historical Context: Andersen Windows and Their Lifespan
Historically, some Andersen windows from the 1950s and 1960s were made with a single flat glass "bubble" construction, which was utterly sealed. This design was effective but, like any sealed system, could be compromised with time. These windows are unique in their construction and lifespan, making it challenging to determine their current production status accurately.
Modern double pane windows have different specifications. They often incorporate rubber seals and specialized gases, typically argon or krypton, which are less reactive and maintain a stable seal for a longer period. These advancements significantly improve the longevity of double pane windows.
For instance, a window replacement I recently had installed replaced a frame damaged by a deer entering the basement. The new window had black edges around the rim, indicating a modern design with improved sealing technology. Unlike the earlier Andersen windows, these modern replacements are expected to have a more definitive lifespan.
Lifespan Varies by Quality and Conditions
The lifespan of double pane windows generally ranges from 15 to 20 years under normal conditions. However, the quality of manufacture and the environmental conditions play a significant role. High-quality windows with precise manufacturing and proper installation can last longer, potentially reaching 30 years or more in favorable conditions.
It is important to note that even under optimal conditions, there can still be minor issues such as condensation between the layers. This condensation, while rare, can be indicative of a minor failure in the seal. Nevertheless, regular maintenance can help prevent such issues from becoming more serious.
Professional Installation and Maintenance
To ensure the longevity of your double pane windows, it is recommended to choose a reputable installer like Elite Windows Doors North West. These companies provide high-quality installation and ongoing support, which can significantly impact the lifespan of your windows.
Professional installation ensures that the windows are correctly sealed and properly set. Regular maintenance, including checking and cleaning the seals, can help prevent premature failure of the windows. This involves inspecting the windows for any signs of wear or damage, tightening or replacing seals if necessary, and ensuring that the gas between the panes remains intact.
Conclusion
While the exact lifespan of double pane windows can vary based on several factors, modern double glazing windows typically last for 15 to 20 years without any significant issues. High-quality manufacture, proper installation, and regular maintenance can extend this lifespan and ensure that your windows continue to provide energy efficiency and comfort for years to come.
