How Does Double Glazing Work?

If you live in an space where winters are notably long, 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-efficient and harder to break. They also do a greater job of reducing noise.

So, how exactly does double glazing work? Contrary to what many individuals think, the principle behind the technology is fairly easy - however it's worth understanding the science to help you to make higher choices about which options are worthwhile, and which are simply marketing gimmicks.

First, two glass panes are held collectively in a frame. Glass panes used in double glazing are often tinted though clear varieties are available. The tint helps to soak up solar radiation so that during the warm summer time months, your house will not really feel like an oven.

The most common tints are bronze, gray, blue and green. Higher-finish glass panes might make use of a combination of reflective, anti-glare and heat-absorbing technologies.

Second, a barrier of air or gas is maintained between the 2 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 way slower in gases (like the air or argon trapped in the spacer) because the particles not only move freely however are also positioned far apart from each other. The impact is improved insulation. Heat does not escape simply from the window. Your own home stays warmer longer.

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

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

There are several factors that may affect the overall efficiency of double glazed windows. These include the kind of window frame used, the thickness of the glass and the space between them.

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