However, these highly efficient windows will keep the gaps between the inner and outer glazes from allowing air inflow or outflow, although this is usually kept to a minimum due to the gases present inside.

The majority of modern windows are energy-efficient and are integrated with advanced coatings that are heat-sensitive. Homeowners have the ability to choose between a variety of window glazing options that include low-E glass, triple-pane insulated glass, double-pane insulated glass, and single-pane glass.

Window glazing is rated on three criteria: its ability to insulate, how much light it filters through, and its ability to block heat from the sun. By evaluating these factors, you can choose the best windows that are the most suited to your climate and even customize windows for specific rooms in your home.

A window’s ability to insulate is measured in a handful of different ways. The most common way to measure this is with the R-Value system, which is a measurement of how well materials resist energy transfer. In this system, the higher R-value translates into greater resistance and thus, higher insulation.
