How Does Double Glazing Work?

When you live in an area where winters are notably lengthy, you will discover it advantageous to switch from traditional home windows to double glazed units. There are various benefits associated with the latter: Double glazed windows are more energy-efficient and harder to break. Additionally they do a greater job of reducing noise.

So, how exactly does double glazing work? Contrary to what many people think, the principle behind the technology is pretty easy - but it's worth understanding the science that will help you to make higher selections about which features are worthwhile, and which are merely marketing gimmicks.

First, two glass panes are held together in a frame. Glass panes used in double glazing are usually tinted although clear varieties are available. The tint helps to soak up solar radiation in order that through the warm summer months, your house is not going to really feel like an oven.

The most common tints are bronze, gray, blue and green. Higher-finish glass panes could make use of a combination 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 occurs very quickly because the particles are tightly packed.

Heat switch is much slower in gases (like the air or argon trapped in the spacer) because the particles not only move freely but are also positioned far aside 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 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 good way to host late-evening events without disturbing the neighbours.

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

There are several factors that may have an effect on the overall efficiency of double glazed windows. These embody 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 windows make the most of only one pane of glass, whereas double glazing makes use of two. Between the 2 panes of glass is an air or gas-filled barrier that works to reduce heat loss and regulate heat gain.
