How Does Double Glazing Work?

In the event you live in an area the place winters are notably lengthy, you will find it advantageous to switch from traditional windows to double glazed units. There are a lot of benefits related with the latter: Double glazed home windows are more energy-efficient and harder to break. Additionally they do a better job of reducing noise.

So, how exactly does double glazing work? Contrary to what many people think, the precept behind the technology is pretty simple – but it’s worth understanding the science that will help you to make better decisions about which options are worthwhile, and which are merely marketing gimmicks.

First, glass panes are held collectively in a frame. Glass panes used in double glazing are usually tinted though clear varieties are available. The tint helps to absorb solar radiation so that during the warm summer months, your house won’t feel like an oven.

The commonest tints are bronze, grey, blue and green. Higher-end glass panes might employ a mix of reflective, anti-glare and heat-absorbing technologies.

Second, a barrier of air or gas is maintained between the two window panes. Called a spacer, this hole is key to reducing heat loss and noise. Heat will always move from higher to decrease temperature. In solids (like glass), this happens very quickly because the particles are tightly packed.

Heat switch is much slower in gases (like the air or argon trapped within the spacer) because the particles not only move freely however are also located far aside from every other. The impact is improved insulation. Heat does not escape easily from the window. Your private home stays warmer longer.

Sound travels slowest by means of air and accounts for a way double glazing can keep noise levels down. Additionally, some spacers come with foam padding designed to soak up echo and muffle sound. This is a superb way to host late-night time parties without disturbing the neighbours.

Finally, the barrier is sealed to prevent the entry of outside air and to avert moisture build-up in the inside glass panes. Typical spacers comprise dessicant as an added precaution against condensation.

There are a number of factors that may have an effect on the general efficiency of double glazed windows. These embody the kind of window frame used, the thickness of the glass and the space between them.

Regardless of the variables, all double glazed windows operate under the identical primary principle. Traditional home windows utilize only one pane of glass, whereas double glazing uses two. Between the two panes of glass is an air or gas-stuffed barrier that works to reduce heat loss and regulate heat gain.
