How Does Double Glazing Work?

If you happen to live in an space where winters are particularly lengthy, you will find it advantageous to switch from traditional home windows to double glazed units. There are a lot of benefits associated with the latter: Double glazed home windows are more energy-environment friendly and harder to break. In addition they do a greater job of reducing noise.

So, how exactly does double glazing work? Opposite to what many individuals think, the principle behind the technology is fairly easy - but it's worth understanding the science that will help you to make better decisions about which features are worthwhile, and which are simply marketing gimmicks.

First, two glass panes are held together in a frame. Glass panes used in double glazing are often tinted although clear varieties are available. The tint helps to absorb solar radiation in order that throughout the warm summer months, your house will not feel like an oven.

The most common tints are bronze, grey, blue and green. Higher-finish glass panes may make use of a mixture 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 transfer is much slower in gases (like the air or argon trapped in the spacer) because the particles not only move freely however are additionally located far apart from every other. The impact is improved insulation. Heat does not escape simply from the window. Your own home stays warmer longer.

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

Finally, the barrier is sealed to stop the entry of outside air and to avert moisture build-up in the interior glass panes. Standard spacers contain dessicant as an added precaution in opposition to condensation.

There are several factors that can have an effect on the overall effectivity of double glazed windows. These embrace the kind of window frame used, the thickness of the glass and the area between them.

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