Energy Saving
LowE Glass

LowE glass is glass that has had an invisible metallic coating applied to the surface. This coating dramatically increases thermal performance of the window by reflecting radiant heat. It is most effective when used in a sealed insulated glass unit that has been filled with inert Argon gas. You can achieve even greater efficiency by using a warm-edge non-conductive spacer to separate the two panes of glass. With the proper LowE coating, your windows meet EPA Energy Star guidelines for energy efficiency.

Yes, the LowE coating works to save you money and keep you comfortable in both heating and cooling seasons. In the winter, radiant heat produced by your heating system is reflected back into your home. In the summer, radiant heat from the sun is reflected, so that the load on your cooling system is greatly reduced. And unlike dark tinted glass, LowE glass allows almost all visible light to pass through.

Be sure to ask for Energy Star when you are selecting your replacement windows. At The Window Source, you are assured in writing that your windows will always be Energy Star compliant for your climate zone when you select the LowE glass upgrade for any of our windows and doors. Selecting LowE glass is a smart investment that will pay for itself quickly, keep your home more comfortable, and reduce fading of fabrics inside your home.
