The Benefits of uPVC Windows with Double-Pane Glass

A major factor to consider when choosing replacement windows is the type of glass used. In this article, we highlight the differences between single- vs. double-pane windows and explain the benefits of double-pane glass.

Single- vs. Double-Pane Windows

The main difference between a single- and double-pane window is the number of glass layers it has. Single-pane windows have one layer of glass that offers wind protection. However, glass is a poor insulator. Experts estimate that 70 percent of energy loss occurs in windows and doors, and 90 percent of window heat loss occurs through the glass. Poor insulation causes the outdoor temperatures to greatly affect the indoor temperature of your home.

What are Double-Pane Windows?

Double-pane windows contain two panes of glass separated by a space of air or gas that helps to slow the transfer of heat and cold. Because gas is denser than air, insulating gas is more energy efficient than air. The two gasses typically used in double-pane glass are Argon and Krypton.

Double-pane glass is also known as double-glazing, insulation-glass-pane, IG-glass, and increasingly triple glazing/pane.

While the initial cost of double-pane windows is more than single-pane windows, the impact on your energy bills will be noticeable. With less heat and cold transferring through your windows, the cost to cool your home will decrease significantly.

Double-Pane Window Benefits

According to, double-pane windows can reduce energy usage by around 20%. It’s important to keep in mind that to see energy-saving results, you must replace all old and failing windows in your home; not just one.

Double-pane windows also help to shield your home from noise. The two layers of glass and insulating gas significantly reduce the amount of outdoor noise pollution that enters your home. This is especially beneficial for homes on busy streets or in noisy neighborhoods.
