80% of most windows are glass. Double-strength glass is thicker, stronger and more protective. It won’t crack, break as easily. Insulated glass package plays a very important role in replacement windows. We all need our houses to be warmer in the winter times and cooler during summer.

There are 2 important factors:
Low-E glass, acts as a thermal barrier. During the winter months, it helps reduce heating use by reflecting indoor heat back into the room. In the summer months, it lets in visible sunlight while minimizing infrared and ultraviolet solar energy. Space between panes of glass (double or triple) is filled with Argon or Krypton gas. Insulating gas prevents heat and cold conduction making your home more energy-efficient and quieter.
