How Does Low-E Make RELIABILT Windows More Energy Efficient? In the winter, Low-E glass lets the warm, solar rays in while blocking the heat in the home from getting out.
Choose Low-E for the most effective, insulating solar control glass available. Its special, double layer of silver coating dramatically limits the sun’s penetrating heat during the summer by reflecting long-wave heat energy. During cold winter months, Low-E maintains your home’s warm, comfortable indoor temperature by permitting short-wave heat energy to enter, while keeping cold temperature out.
In the summer, Low-E glass reduces heat gain from the sun to help keep the home cooler.

Low-E Glass with Argon Gas
Argon gas works like an insulating blanket between two panes of glass to further improve thermal efficiency and decrease outside sound levels.
