If you are planning to build a new house, it is important to think about the type of windows you'll use. Windows can cause unwanted heat gain or loss that contributes significantly to your domestic heating and cooling expenses. The good news is that some modern styles of windows are designed to help make your home more energy-efficient despite the potential for passive energy loss.

Over the years, the demand for double-glazed windows has been rising in both the residential and commercial construction markets. Growing demand for these windows can be attributed largely to their design, which lends itself to energy-efficient construction. 

If you are holding back from choosing double-glazed window units for your home because of a lack of knowledge and awareness of how they work, you have come to the right place. Read along to find out how double glazing helps save energy and reduce energy bills in the home.

Double-Glazing Forms an Insulating Barrier Between Your Home and the Outside World​

A double-glazed window unit comprises two panes of glass with an air gap between them. Because the two layers of glass trap air in, thermal energy is not going to move through your windows as easily as it does through single-glazed versions. 

During the colder months of the year, single-glazing does little to prevent heat loss, as the cold air on the outside of the glass draws heat from the warmer home interior environment. With double-glazing, heat has to move through one pane of glass plus the air space before it can reach the second pane, significantly slowing down the movement of thermal energy.

To reduce heat loss and increase the thermal performance of double-glazed windows even further, the air trapped between the two panes of glass can be replaced with an inert gas such as argon. Inert gases not only increase the thermal performance of glass windows but also help insulate against outside noise.

Double-Glazing Can Be Specially Coated to Minimise Passive Energy Loss​

Modern window manufacturers have seen the potential for increasing the thermal performance of double-glazed windows with advanced glass coating technology.

The inside pane of glass is specially coated to reduce the amount of heat lost through conduction and convection. On the other hand, the outer pane of glass is specially coated to prevent excess solar heat radiation through your windows.

As more heat will be retained within your home, you can keep warm and comfortable year-round without incurring huge energy bills.

While installing quality double-glazed windows helps make your home more energy-efficient, it does not eliminate the need for proper residential insulation and air-sealing. To achieve superior levels of energy efficiency, you need to think about the potential for passive energy loss throughout the home.
