Choosing the Best Glass for Your Windows
Windows are not just for decoration, you want a window that will be energy efficient as well.
Windows are one of the most important features of a home, both in terms of overall appearance and resale value. Glazed doors and windows can leak energy if they are not well chosen and installed correctly. With the cost of energy, it's a smart move to utilize high-performance glazing.
Many companies, such as Milgard and Andersen offer ready-to-install windows and doors that come with different glass options. But what if you're replacing glass in existing window or door frames? How do you know which kind of glass to choose?
According to Home Tips , two important ratings to check are the R-Values and U-Values.
R-Value: Thermal resistance – the ability of a material to resist heat flow – is measured by an R-value. The higher the R-value, the more the material resists the movement of heat. For example, a single-glazed window offers an insulating value of about R-1; a dual-glazed model provides twice the value at R-2. The type of glass is the most important factor when it comes to R-values.
U-value applies the factor of time to the heat-loss measurement. U-values measure heat that escapes per hour through the window. Windows typically have two U-values: one for the glass and one for the entire window, including the frame. The lower the U-value, the more energy-efficient the window.
Another option to consider is Low-E (low emissivity) glass . This type of glass offers ...
