Product Description
Low-E glass has a low rate of emission - that is it has a lower rate than clear float glass of allowing heat to pass through the glass. In other words, if there is a heat source inside your house (or outside), the glass bounces the heat from that object back away from the glass. So, in the winter months, if you have Low-E glass in your home, much of the warmth (heat) given off by air conditioners, heaters and all the objects which they have heated, is bounced back into the room. In the summer, the same thing happens but in reverse. The sun heats things up (the air, sidewalks, driveways, next door neighbours bricks, etc. ) outside of your house. This heat radiates from those objects and tries to get into your house. With Low-E glass much of this heat bounces off the glass and stays outside. There are two types of Low-E glass: Online coated Low-E (hard coat) and offline coated Low -E (soft coat). As you might imagine, they have different properties. In fact, they actually look different.
