Why Low-E Coating is an Important Factor When Shopping for Window Glass Replacement?

Window Glass Replacement Johns Creek, GAThere are actually two different types of low-e coatings: passive low-e coatings and solar control low-e coatings. When shopping for window glass replacement it is a good idea to research the effectiveness of glass with low-e coating.  Simonton Window’s has developed innovative high performance glass packages designed to meet homeowners needs. Glass is one of the most popular and versatile building materials used today   One reason is because of its constantly improving solar and thermal performance.Low-e coatings have been developed to minimize the amount of ultraviolet and infrared light that can pass through glass without compromising the amount of visible light that is transmitted.   Click in this link to get more detailed information on Low-E Coating from Idea Scapes educationcenter.ppg.com/glasstopics/how_lowe_works.aspx

The following are used to measure the effectiveness of glass with low-e coatings:

  1. U-Value is the rating given to a window based on how much heat loss it allows.
  2. Visible Light Transmittance is a measure of how much light passes through a window.
  3. Solar Heat Gain Coefficient is the fraction of incident solar radiation admitted through a window, both directly transmitted and that is absorbed and re-radiated inward. The lower a window’s solar heat gain coefficient, the less solar heat it transmits.
  4. Light to Solar Gain is the ratio between the window’s Solar Heat Gain Coefficient (SHGC) and its visible light transmittance (VLT) rating.
