Everything you Need to Know About Glass

Layers of Glass


  • Also known as single-glazed window with clear glass allows more daylight to pass through it than any other type. It, therefore, has very little insulating value. It provides only a thin barrier to the outside and thus accounts for considerable heat loss and gain.


  • Double-pane window, also known as dual paned or double glazed, is the most popular choice of today in window replacement. Because multiple layer of glass increase the window’s ability to resist heat flow, double-pane windows insulate much more than a single windowpane would.


  • Also known as triple glazed, triple-paned windows are even heavier and more expensive than double-paned windows. These windows create an even more energy efficient window. A window with three panes is an investment rather than a purchase; it is most often used for northern climates and as soundproofing near airports and highways.
