...hotter than the outside, the low-e coatings work best on the inside window pane, on the side that faces toward the outside. Q: What is U-Value? A: The U-value, also called the U-factor, is a measure of how well heat flows through an object (thermal conductivity). It is also referred to as the heat transfer coefficient or the coefficient of heat transmission. See #1.

...Low-E coatings are microscopically thin, virtually invisible, metal or metallic oxide layers deposited on a window or skylight glazing surface primarily to reduce the U-factor by suppressing radiative heat flow. The principal mechanism of heat transfer in multilayer glazing is thermal radiation from a warm pane of glass to a cooler pane. See #9.
