What Does Low-E Mean?

Low-E window glass is glass with a low level of emissivity, also known as the ability of a material to emit energy as thermal radiation. By utilizing a thin, transparent coat, Low-E window glass reflects heat while allowing as much natural light as possible to pass through the window itself. Low-E also means that a house’s temperature can consistently reflect the interior temperatures inside while blocking exterior temperatures from passing through the glass (for a broader explanation, see our post on Low-E Window Glass).

What is Low-E 240?

When window glass glare is your top priority, Low-E 240 glass should be your Low-E glass of choice. A specially treated version of Low-E, this type of window glass is the best at controlling glare regardless of the level of light coming into your home.

On the contrary, Low-E 366 is known in circles as one of the premier performance types of Low-E glasses. Low-E 366 glass provides some of the highest levels of comfort all year-round while simultaneously delivering some of the biggest energy savings.
