Choosing new or replacement windows for your home involves more than simply getting the look right – you need to select the right glass for your climate.

Window glass treatment, known by professional contractors as ‘glazing’, makes a huge difference in how comfort your home feels, as well as the size of your electric bill. Gone are the days of the single-pane windows, these days experts stress the importance of installing higher-efficiency windows to homeowners. When you understand the different types of window glazings, you can better choose the right windows for your home.

Double-Pane Insulated Glass: This is the most common type of window installed. It is constructed by sandwiching a layer of inert gas between to window panes. Since inert gas is a poor thermal conductor, double-pane insulated glass windows keep interiors more comfortable.

Triple-Pane Insulated Glass: If two layers of window panes are better than one, three layers must be better still. Triple-pane insulated glass provides excellent insulation for extreme temperatures as well as reducing exterior noise, but it comes at a price. This type of window glazing is heavy, thick, and more expensive.

Whether you choose single-, double-, or triple-pane windows, there are more ways to lower your home’s energy use.

Low-emissivity Coating: This invisible coating of metallic oxide comes standard for most of today’s new windows. Low-E, as it is more widely known, can cut energy costs by as much as 25%. Customers have the option to customize the low-E coating to best suit their climate.

Heat Mirror Glass: This type of glazing fills the space between a double-pane window with a thin film of low-E. This high-tech window glazing provides the same, or even better, energy saving provided by the triple-pane insulated glass, without the weight and thickness.

Deciding on the right windows for your home requires making a compromise between your current window budget, and the amount of energy savings you want in the future. Remember, energy efficiency differs even among windows with the same glazing. Look for an Energy Star sticker on the window, or speak with a window expert for choosing the best windows for your home.
