Double Glazing- How Does It Work?

Most homes in Australia and around Melbourne have insulation in the walls and roof. This means that the majority of heat loss and gain into your home is through your windows and doors. So why do very few homes have double glazed windows and doors?
You could think of double glazing as insulating your windows and doors. If it is hot and cold enough to warrant insulating your walls, why not your windows?

Double glazing works by providing a type of insulating gap between the two panes of glass. With our double glazed units, this gap is filled with Argon gas, which has much better thermal properties than air. Quality double glazing will prevent condensation from forming inside your home when it is warmer inside than out.

The interior pane of glass is Low E glass, which further acts to stop heat escaping out through your windows in winter when it is colder outside than in.

uPVC double glazing is far superior than timber or traditional aluminium products as the uPVC frame is very stable and therfore suffers from minimal expansion and contraction with temperature change. Timber frames move much more due to the nature of timber, meaning that the double glazing is not as stable and more likely to fail. Aluminium is not suitable (unless thermally broken with a polyamide core) because aluminium is a metal, meaning that heat will be conducted through the frame itself.
