Type of Glass Classification

Clear Glass (Dual or Tri-pane) – Glass is  two or three panes thick and clear with no special coatings applied to them. The panes of glass are spaced about 1 ¼ cm (½  in) apart, and the air in between the panes of glass acts as an insulation barrier.









Low-E (Low Emissivity) Glass – Low-E is a coating that can be applied to the glass to make it more energy efficient, the heat generated by your furnace is reflected back into your home. Low-E generally has a neutral appearance when viewed from the outside and inside however sometimes they can become quite reflective.







SunStop/UV Reflective Coated Glass – SunStop uses two layers of Low-E laid over top of one another to block out the sun’s energy, reflecting heat while still allowing a maximum amount of visible light into the house. This keeps your home cooler during the summer and warmer during the winter. The coating results in making the windows reflective.
