How Does Double Glazing Work?

If you happen to live in an space where winters are significantly lengthy, you’ll find it advantageous to switch from traditional 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. Additionally they do a better job of reducing noise.

So, how exactly does double glazing work? Opposite to what many people think, the principle behind the technology is pretty easy – however it’s price understanding the science to help you to make higher decisions 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 usually tinted although clear varieties are available. The tint helps to soak up solar radiation in order that throughout the warm summer time months, your house won’t feel like an oven.

The most common 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 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 far slower in gases (like the air or argon trapped within the spacer) because the particles not only move freely but are also located far other than each other. The effect is improved insulation. Heat does not escape simply from the window. Your own home stays warmer longer.

Sound travels slowest through 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 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 internal glass panes. Typical spacers contain dessicant as an added precaution towards condensation.

There are a number of factors that can have an effect on the general effectivity of double glazed windows. These include 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 same fundamental principle. Traditional windows make the most of only one pane of glass, whereas double glazing uses two. Between the 2 panes of glass is an air or gas-stuffed barrier that works to reduce heat loss and regulate heat gain.
