Double Glazing

Double glazing is an effective way to insulate your property. With a large amount of heat escaping from inefficient windows, it’s important to have well-sealed and high performing window systems. Double glazing is now standard in all new-build properties. There are, however, many houses with single glazed windows or old, poorly functioning double glazing. This is particularly true in the South East of England. A government survey found that there were more than twice as many properties with single glazing in the South East compared to the rest of England.

How does double glazing work?

Double glazing consists of two panes of reinforced glass hermetically sealed into an insulating frame. The space between the glass panes is filled with an inert gas such as Argon or Krypton to enhance insulating capacity. When installed, the sealed unit is accurately fixed into the wall space and sealed with durable beading. Double glazed windows have been proven to improve a property’s insulating capacity making potential energy savings of up to £75 a year on heating bills, amongst other benefits.
