Explaining the Causes of Foggy Glass and Condensation on Windows
Insulated Glass Units: The Standard for Residential Windows
Insulated glass units (IGUs) are a type of window commonly used in residential homes. They consist of two or more layers of glass separated by a spacer and sealed along the edges. The space between the glass panes is filled with an inert gas, such as argon or krypton, which helps to improve the insulation properties of the window. IGUs are designed to reduce heat loss in the winter and heat gain in the summer, resulting in increased energy efficiency and comfort in the home. They are also known as double-paned or triple-paned windows, depending on the number of layers of glass used.
Understanding the Causes of Foggy Glass in Insulated Units
Foggy glass in insulated glass units can be caused by the failure of seals around the edges of the unit, allowing the escape of inert gas and the infiltration of outside air. When the weather is cooler, moisture in the air can condense on the cold outer glass, creating a hazy appearance. This issue is common in IGUs, as all units eventually lose their gas filling and the seals have a limited lifespan. Factors such as temperature fluctuations, atmospheric pressure, wind, sunlight, and water can affect the seals’ longevity. According to the International Association of Certified Home Inspectors, all units lose 1% of their gas per year. If foggy glass appears within the window’s warranty period, it is recommended to contact the manufacturer for potential replacement under the terms of the warranty.
Triple Glass Upgrade: The Ultimate Solution to Foggy Glass
Upgrading to triple glass can fix the foggy glass issue by providing an additional layer of insulation. This can help to prevent the infiltration of outside air and the resulting condensation on the outer glass, which is the cause of the foggy appearance. The added insulation of triple glass can also help to improve the overall energy efficiency of the window, reducing heat loss in the winter and heat gain in the summer. Additionally, the increased thickness of triple glass can provide increased sound insulation and added durability compared to traditional double-paned windows. Overall, upgrading to triple glass can provide a long-term solution to the issue of foggy glass and offer a variety of additional benefits.
Get the Most Out of Your IGUs with Low-E Coating
Low-E coating is a thin layer of material applied to the surface of insulated glass units (IGUs). It is designed to reflect infrared light, which is a type of electromagnetic radiation that is responsible for the transfer of heat. By reflecting the infrared light back towards its source, Low-E coating can help to reduce the amount of heat that passes through the window, increasing its energy efficiency. In addition to reflecting heat, Low-E coating can also help to block harmful ultraviolet (UV) rays, which can fade furniture and carpets. Low-E coating is a common feature in IGUs and can be applied to either the inner or outer surface of the glass, depending on the desired performance and location of the window.
Replacing IGUs vs. Entire Windows: What’s the Best Option?
The cost of replacing insulated glass units (IGUs) in a residential home is generally less expensive than replacing the entire window. This is because IGUs can often be replaced without the need to remove the entire window frame, which can save time and labour costs. The cost of replacing IGUs will depend on the size and type of window, as well as the materials used. In general, IGUs can range in price from a few hundred dollars to over a thousand dollars, depending on the specifics of the job. On the other hand, replacing an entire window can be significantly more expensive, as it requires the removal and disposal of the old window, as well as the installation of a new one. The cost of replacing an entire window can range from a few hundred dollars to several thousand dollars, depending on the size, style, and materials used. Ultimately, the cost of replacing IGUs or an entire window will depend on the specific needs and budget of the homeowner.
To summarize, IGUs are a popular option for residential windows because they provide energy efficiency and comfort. However, the seals in IGUs can break down over time, causing the issue of foggy glass. Upgrading to triple glass can solve this issue and provide additional benefits, such as improved energy efficiency, sound insulation, and durability. Low-E coating can also improve the performance of IGUs by reflecting heat and blocking UV rays.
