Triple Glazing vs Double Glazing

Triple glazing is essentially an upgrade from double glazing because it has an additional pane of glass. Whereas double glazing is installed with two panes of glass, triple glazing has three which creates two sealed cavities.

The additional layers of glass can provide more benefits. During this time of increasing energy costs in Dunstable, it makes sense for people to consider triple glazing for their home or business because that additional pane of glass can improve conditions significantly. As well as the additional layer of glass, triple glazing comes with a layer of insulating gas in the centre pane.

The inert gas is usually argon which is thicker than air meaning it will trap as much heat as possible which is where the high triple glazing energy rating comes from. This is known as the U or G value.

We have a range of options for triple glazing and can ensure that windows with this extra pane of glass fit in with your needs every time. Our windows will be made to the exact square metre requirements for your home and we have a range of options.

This additional layer of argon gas, which is an insulating gas that is heavier than air and therefore makes a great thermal layer, is what makes triple glazing so effective.

This is commonly installed in the centre pane, between the two layers of glass for the best performance. It can contribute to how effective this window reflects heat, offering better temperatures inside the home and reduce carbon emissions.
