Simply put, double glazing involves sandwiching two panes of glass together, with a hollow aluminium spacer bar in between which contains a substance to remove any residual moisture. The glass is airtight and it is the trapped air that in effect provides the insulation, reducing heat loss by as much as 51%.
A double glazed panel may be made even more efficient by using a special low-emissivity glass, which loses less heat. The still air between the panes could also be replaced with an inert gas such as argon.
At Rylock Windows Geelong , we source all of our double glazing from specialist suppliers who provide a six year guarantee on all of their products. Our standard guarantee of a replacement panel is also extended to the onsite fitting, should a fault occur.
