Not all double glazing is created equal

Low E – Glass, has a thin silver coating applied during the glass manufacturing process, which allows the microscopic coating to fuse onto the hot glass. The Low-E coated glass is placed on the inside facing pane within the insulated double glazed window unit.

With this coating, U Values, like an R value, which is a number given to a window unit based on how much heat loss it allows, are reduced with Low-E glass being between 2.5 to 5 times more efficient than uncoated double glazed windows.

Low-E insulated glass units have very little negative impact on visible light transmission and allow large amounts of free solar energy to enter the building. By adding a thermal spacer and filling the unit with argon gas, you significantly increase your insulation performance on a standard window unit.

Low-E coating technology offers energy efficiency and can play an important role in the overall performance of a window, significantly affecting the overall heating, lighting, and cooling costs of your home.
