How Does Double Glazing Work?

With the emphasis on energy efficiency nowadays, it’s no wonder that most properties now have some form of double glazing. This is one of the most effective ways of creating a space that is thermally efficient.

Even minimal heat leak can mean we pay out more on our utility bills. Did you know that poor double glazing performance can add as much as a couple of hundred pounds to your heating bills over 12 months.

However, it’s not just heat retention that double glazing is known for – it’s ideal for home security and can reduce the amount of noise coming from outside. Before the 1980s, more homes than you think would simply had single pane windows – double glazing is actually quite a modern staple to properties throughout the UK.

How Does it Work?

A double glazed bifold door uses two sheets of toughened glass with a small gap in between. The space is usually about 16mm and the space is filled with an inert gas such as argon. Inert gasses have low thermal conductivity compared to normal air.

There’s no point in having highly efficient glazing without ensuring the frame is also thermally efficient. NOW Aluminium bifolds, for example, are slimmer and lighter than most frames, making sure that the amount of glass is maximised. Our NW1 bifold frame is thermally broken which makes it incredibly energy efficient – keeping the heat inside in the winter and warmth out in the Summer.

You can compare how energy efficient bi-folding doors are by looking at a measurement called the u-value, also known as heat transfer coefficients. Put simply, this relates to the amount of heat that gets transferred from one side of the glass to the other. The lower the value, the less heat that is transferred and the more energy efficient the door system.
