Double glazing is the general term used for uPVC and replacement windows and doors. Gaining more information about their basic features and benefits can help you understand why double glazing could give you a lot more than just wonder looking windows.
What is double glazing? Today, the terms seems to be common enough to be heard on the streets but what does it really mean?
In the earlier times, windows were simply holes in the wall. Thanks to the various advancements on windows, the once bare hole is now covered with double glazing. Double glazing is basically the process of combining two panels of glass, kept apart by a spacer bar that contains tiny silica balls, then sealed together. The purpose of the silica balls is to keep moisture out of the space between the two panels. The glass used in double glazing is a special type of glass that meets the requirements of FENSA as an energy efficient product.
Homes with double glazed windows are known to give residents elegant looking windows that are energy efficient. Both the air and the glass of the windows prevent heat from going in and out of a home. This in turn will help keep the temperature of a room stable, and prevent the air conditioner or furnace from working too hard. Cuts on heating and cooling bills are evident with double glazed windows.
Double glazing has a few other associated terms you need to understand – toughened and float glass, Argon sealed units, and low-e. Understanding these terms will help you get the right kind of double glazing units for your home.
Float or toughened glass – Flat glass is often used for small double glazing units while toughened glass is for large units. Toughened or tempered glass is recommended for double glazing since they shatter into thousands of small pieced instead of big sharp glass shards when broken. This makes them safer and can prevent major injuries.
Argon sealed units – Argon filled double glazing is more effective than air filled units because Argon is an inert gas that reduces heat conductance between the two glass panels.
Low emissivity or Low-E – When combined with Argon filled units, the low e glass works twice as better. Low-e glass is applied with microscopic coating that reflects heat.
These three can affect the effectiveness of your double glazing as an insulator. If you are interested in having double glazed windows in your home, make are you work with a FENSA registered company to protect your double glazing units.
