What Low-E4 Window Glass Is

Low-E stands for “low emissivity,” a term that refers to coatings applied to the glass when it’s manufactured in order to effectively block or reflects certain types of light that produce heat. Low-E glass generally lets visible light pass through the glass, while reducing the heat from either escaping your home or entering from outside.
