How Does Double Glazing Work?

Should you live in an space where winters are particularly long, you can find it advantageous to switch from traditional windows to double glazed units. There are a lot of benefits related with the latter: Double glazed windows are more energy-environment friendly and harder to break. Additionally they do a greater job of reducing noise.

So, how precisely does double glazing work? Contrary to what many individuals think, the principle behind the technology is pretty simple - but it's value understanding the science to help you to make better decisions about which features are worthwhile, and which are simply marketing gimmicks.

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

The most common tints are bronze, gray, blue and green. Higher-finish glass panes might make use of a mixture 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 lower 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 within the spacer) because the particles not only move freely but are also positioned far apart from every other. The impact is improved insulation. Heat does not escape easily from the window. Your house stays warmer longer.

Sound travels slowest by means of air and accounts for the 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 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 within the inside glass panes. Conventional spacers comprise dessicant as an added precaution towards condensation.

There are several factors that can affect the general efficiency of double glazed windows. These embody the kind of window frame used, the thickness of the glass and the house between them.

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