Double Glazing works by containing air or argon gas between two panes of glass; this trapped air or gas acts as a thermal barrier reducing the amount of heat transferred from inside to out.
Double glazed windows are a brilliant way of reducing the amount of heat loss in your home, just by replacing your old single glazed windows you could reduce the amount of heat lost, by up to 30%.
Modern double glazed units generally use a gas, such as argon to reduce heat loss further, the argon gas inside the two panes of glass acts as a barrier which is used to reflect heat back into the property.
Argon gas filled units can also help to keep the heat out in the summer, giving a more relaxed feel during those summer months.
Double glazing is also a brilliant way to reduce sound from outside of the home, installing quality double glazed windows could make your home much quieter.
How does double glazing insulation work
The two panes of glass create an airtight seal which traps air or gas in between them to create the thermal bridge; this thermal bridge reduces the amount of heat that escapes from the property.
Modern UPVC frames also contain several chambers that trap air; these chambers reduce the levels of heat that is able to be transferred by the window frame.
A+ rated frames, and argon gas filled double glazed units can mean significant savings on your energy bills, and a property that feels much more comfortable to inhabit.

What is double glazing, and how does it work?
The term double glazing is referring to the two panes of glass that make up a double glazed unit; most people think that it has something to do with UPVC frames that make up a double glazed window but in-fact it is the glass that makes it double glazing.
Double glazing is a way to reduce the amount of heat lost through the window opening in a home; older style single glazed windows acted as a bridge allowing internal warmth to be escape through the glass.
Although glass is an insulator and does not transfer heat efficiently, it does transfer heat, and with glass windows generally being only around 4mm thick, heat can move with very little resistance.
Another problem that was solved by the introduction of the double glazed unit was the condensation problem; single glazed windows condensate very easily due to the rapid cooling of moisture within the home hitting the glass.
Double glazing can still create condensation but this is usually because of a misted unit, if you have this problem take a look at our guide for how to demist double glazing.
With modern double glazing this should not happen, if it does it will be a manufacturing problem that will be covered under warranty.
