When you\u2019re choosing windows for your home or office, you\u2019ll probably hear the term Low-E glass. But what exactly is it?<\/p>

\"Low<\/p>

Low-E stands for Low-Emissivity. In simple words, emissivity is a material’s ability to radiate heat. Low-E glass is specially designed to control how heat moves through your windows. It has a very thin, almost invisible metallic coating that reflects heat while still allowing plenty of natural light to pass through. Think of it like sunglasses for your windows \u2014 blocking what you don\u2019t want while keeping what you do.<\/p>

How Low-E Glass Works<\/h2>

\"Low<\/p>

To really understand why Low-E glass is so effective, let\u2019s break down how it works \u2014 without getting too technical.<\/p>

What Is Emissivity and Thermal Radiation?<\/h3>

Every object gives off heat in the form of infrared energy. This is called thermal radiation. Even your windows do it. Emissivity is a measure of how much heat a surface releases. Regular glass has high emissivity, which means it lets a lot of heat escape or enter your home.<\/p>

That\u2019s where Low-E glass<\/a> comes in. Its special coating lowers the emissivity of the glass, reducing the amount of heat that passes through.<\/p>

The Secret Is in the Coating<\/h3>

\"Low<\/p>

Low-E glass has a microscopic metallic coating \u2014 thinner than a human hair and nearly invisible to the eye. This coating reflects heat back to where it came from:<\/p>
