The term “low-E” refers to glass that has a very thin layer of metal or metallic oxide on top of it, usually silver or tin oxide. Putting this layer on the glass’s surface makes it better at keeping heat in by lowering the amount of heat that moves through it. What “emissivity” means is how much light energy a substance gives off. If you need Low-E glass for a current or upcoming project, our team at Custom Glass Products can help.

  • Invisible: You can’t really see Low-E coating with the naked eye. It’s so thin that it doesn’t change how the glass looks. However, this coating has a big effect on the glass’s thermal qualities.
  • Infrared Radiation and Natural Light: Low-E glass is made to reflect infrared radiation, which is when heat moves from one place to another through infrared light. At the same time, the coating allows natural light to pass through, which is beneficial for those inside as natural light is thought to improve mood and focus.
  • Controlling Heat Flow: Low-E glass stops heat from moving from the inside of a building to the outside by acting as a thermal barrier. The opposite occurs during the warmer months when the glass stops heat from entering. Both situations benefit the HVAC system by relying on it less and increasing its longevity.

Using Low-E glass helps make buildings more environmentally friendly and energy-efficient, which is a bonus for your clients. Contact our team today to learn more.
