Low e glass windows offer insulation against heat and cold. Each layer of glass, in addition to the air spaces in between, resist heat flow. What jonr proposes will reveal solar heat gain differences. Unfortunately, the only way to get rid of the fog is to replace the sash. Select windows with both low U-factors and low SHGCs to maximize energy savings in temperate climates with both cold and hot seasons. Contact your local Overhead. You can save up to 35 dollars in energy costs per window per year. Low E stands for ‘low emissivity’, which means the glass reflects more heat and solar rays than plain glass does. One type of specially coated glass is low-e, or low emittance, glass. Low emissivity (low e or low thermal emissivity) refers to a surface condition that emits low levels of radiant thermal (heat) energy. There is also Low-E 2 (or Low-E squared) for even greater benefits. When Low E units are made the #2 surface will always be the Low E surface and placed accordingly with the Low E toward the outside, ALWAYS. These coatings have been successfully used in residential and commercial applications since 1983. , added six colors to its low-E SunGuard advanced architectural glass product line. There are lots of reasons to replace your windows, but realizing immediate savings on your energy bill isn't one of them. It`s a different glass than standard E-glass and is about 30% stronger and 15% stiffer. As you might imagine, they have different properties. Their appearance approaches that of clear glass. The low-e coating lowers the U-factor of the window, and different types of low-e coatings have been designed to allow for high solar gain, moderate solar gain, or low solar gain. Browse our EnLiten flush-glazed designs for a more expansive view. Glass thickness is rarely mentioned, or even understood, with respects to most professional window sales people. Low-Emissivity Glass Your IG unit will typically be made with low-E glass, which has a coating that reduces the ultraviolet and infrared light that passes through a window.
