How Does Double Glazing Work?

In the event you live in an space where winters are particularly lengthy, you'll discover it advantageous to switch from traditional home windows to double glazed units. There are many benefits related with the latter: Double glazed windows are more energy-efficient and harder to break. In addition they do a greater job of reducing noise.

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

First, glass panes are held collectively in a frame. Glass panes utilized in double glazing are normally tinted although clear varieties are available. The tint helps to absorb solar radiation in order that in the course of 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 could employ a mix 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 gap 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 in the spacer) because the particles not only move freely but are additionally positioned far aside from every other. The effect 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 how double glazing can keep noise ranges 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 parties without disturbing the neighbours.

Finally, the barrier is sealed to forestall the entry of outside air and to avert moisture build-up within the inner glass panes. Typical spacers comprise dessicant as an added precaution towards condensation.

There are several factors that can have an effect on the general effectivity of double glazed windows. These embrace 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 same fundamental principle. Traditional 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-stuffed barrier that works to reduce heat loss and regulate heat gain.
