The type of gas used in Insulating Glass Units (IGUs) can have an impact on their longevity, but it is not the only factor. Several factors contribute to the overall durability and longevity of IGUs, and the choice of gas is just one consideration. Here are some factors to keep in mind:
5 Factors Affecting Longevity of IGUs
- Gas Permeability: Over time, gases can permeate through seals and affect the insulating properties of the IGU. The choice of sealant material and design, as well as the gas used, can influence the rate of gas permeation. Quality seals and proper manufacturing and quality processes are crucial to maintaining the longevity of gas-filled IGUs.
- Seal Integrity: The longevity of IGUs is highly dependent on the integrity of the seals that keep the gas between the glass panes. If the seals fail, it can lead to the escape of the insulating gas and compromise the performance of the window. Seals may degrade over time due to exposure to weather, UV radiation, or other environmental factors.
- Quality of Components: The overall quality of the IGU components, including the glass, spacer materials, and the frame, can impact its longevity. High-quality materials and manufacturing processes contribute to the durability of the IGU.
- Maintenance: Regular maintenance and proper installation are important for the longevity of IGUs. Proper installation ensures that the seals are intact and the IGU functions as intended. Maintenance practices may include checking and, if necessary, replacing damaged seals.
- Environmental Conditions: The local climate and environmental conditions can also affect the longevity of IGUs. Extreme temperatures, exposure to moisture, and other environmental factors may impact the performance of the IGU over time.
While the choice of gas (such as argon or krypton) in IGUs can influence their thermal performance, which is important for energy efficiency, the factors mentioned above play a crucial role in determining the overall longevity and performance of IGUs. Regular inspections and adherence to recommended maintenance practices can help extend the lifespan of gas-filled IGUs.
