For example: usually the glass is coated on the inside of the outer pane for double-pane windows. This film coating reflects radiant infrared energy, which is meant to keep the energy on the same side it originates from while still letting in visible light.
So when the sun shines, a Low-E coated window reflects a lot of that unwanted energy back towards the sun instead of letting the heat pass through the glass. It works the same way if you are running your heater. There are a couple different methods used for coating Low-E windows. Pyrolytic coatings are applied at very high temperatures at the plant when the glass is manufactured. Hard coat Low-E glass surfaces are considered to be medium grade energy efficient windows and perform much better than plain clear glass.
The second method is called Magnetron Sputtering. This process takes place when the glass is placed in a vacuum chamber and has several thin layers of silver with antireflective properties applied to it.
Soft coat Low-E glass is the most efficient and highest performing of the two energy efficient window types. Soft coat Low-E windows are the type we sell at Glass-Rite.

The soft-coat has lower emissivity and superior solar control performance. Visible light transmittance measures how much visible light your product allows into the home.
This number ranges from and the higher the number, the more visible light is transmitted. High visible light transmittance can reduce the need for artificial lighting.
There are several ways that a homeowner can benefit from a Low-E glass package, but the most prominent being energy efficiency and the cost savings associated with that.
Low-E glass packages for northern climates are designed to allow thermal energy into the home, which correlates with lower heating bills. Low-E glass packages in southern climates are designed to do the opposite, reflecting thermal energy away from the home, keeping your home cool and reducing the need for air conditioning.
In addition to the energy efficiency benefits, Low-E glass also prevents discoloration of fabrics and furniture by blocking ultraviolet energy from entering the home. Advancements in the fenestration industry have reshaped the way we think of windows and doors. Not only are they a means to view the inside and outside of the home, but they are also a crucial component when considering the overall energy efficiency of your home. When deciding on windows for your next build or remodel, be sure to discuss which Low-E glass package will work best for you.

Ultraviolet Energy UV energy is one of the most dangerous forms of energy present in the solar energy spectrum and is invisible to the human eye. Visible Light Visible light lies in the middle of the solar energy spectrum and as the name suggests, is visible to the human eye in the form of colors.
Infrared Energy Infrared energy occurs at the opposite end of the solar energy spectrum as ultraviolet energy.
