DOUBLE GLAZING
When choosing glass for your windows, sliding doors, French doors, and entry doors, you need to look at the
glazing aspect. Double glazing refers to windows that have two sheets of glass that are sandwiched together
to create one sturdy layer of glass. Double-glazed glass has excellent performance and is preferred to glass
that is made from one sheet only. There is triple-glazed glass as well, and this is made up of three sheets of
glass.
Using double-glazed glass for your windows and glass doors can improve the energy efficiency of the home.
The space between the sheets is usually a vacuum, and in other instances, it is filled with a gas. This vacuum
or gas-filled space prevents heat loss or gain through the windows or doors. As a result, you don’t have to
worry about losing heated or conditioned air from your home during the cold or hot season respectively. The
triple-glazed glass is usually even more efficient, but you can opt for double glazing as it’s more affordable
and sufficiently energy efficient.
