If you are purchasing windows, either for new construction or as replacement windows, you may be amazed at the number of options available, ranging from the very simple to the very complex. One feature you will most likely encounter among these options is low-E glass.
Low-E stands for low emissivity, which is the ability of a surface to radiate energy. Low-E glass is made by applying a non-visible, microscopic metal coating or metallic oxide to the surface of a pane of glass. This coating reflects the part of the light spectrum that transmits heat, reducing the amount of heat the escapes or enters the home through the windows. This maintains a more comfortable, consistent temperature in your home year-round. Low-E windows also block UV rays, reducing fading to furniture and other items.
Energy Efficiency
There are two types of metallic low-E coating: a hard coat and a soft coat. A hard coat is created by applying tin directly to the molten glass. For a soft coat, silver is applied after the glass has set. Of the two, soft coat low-E glass has better insulating properties.
Even the placement of the low-E coating is important. The specific placement of the metallic coating makes a significant different in how the window directs heat. For this reason, different placements should be used in different climates. In colder areas, where retaining heat is a priority, the low-E coating should be applied to the interior pane of glass. This keeps heat from escaping the home, and saves on winter heating bills. In warmer climates, the goal is to keep heat from entering the home, so the coating should be applied to the exterior pane of glass. This reflects heat back outward and keeps the A/C bills low.
