How Does Low E Glass Work?

Low-e stands for “low emissivity”. Low-e windows contain glass that has been coated in invisible layers of metallic oxide. This coating allows natural light to enter the home while deflecting uv rays and infrared light back out into the environment.

How Does Low E Glass Work?

Low–E glass is a type of glass designed to reduce the amount of ultraviolet and infrared light that passes through it.

It is an energy–efficient solution that has become increasingly popular in the construction of modern buildings and homes.

Low–E glass works by reflecting heat away from the building, while also allowing light to penetrate the glass. This results in a building that is kept cooler in the summer months and warmer in the winter months.

Low–E glass is created by applying a special coating to the glass that is designed to reflect infrared light. This coating is typically made up of a metallic oxide, such as tin or silver, and is applied to the surface of the glass in a process called magnetron sputtering.

This coating is practically invisible to the eye, but it is effective at reflecting the infrared light away from the building. This coating also helps to reduce the amount of ultraviolet light that passes through the glass, which can cause discoloration and fading of textiles and furniture in a home or building over time.

In addition to the reflective coating, Low–E glass often includes an additional layer of insulation in the form of a gas–filled space between two panes of glass. This gas–filled space can be filled with arg
