How Does Double Glazing Work?

In case you live in an area the place winters are particularly lengthy, you will see that it advantageous to switch from traditional windows to double glazed units. There are a lot of benefits related with the latter: Double glazed home windows are more energy-environment friendly 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 precept behind the technology is fairly easy – however it’s worth understanding the science to help you to make higher choices about which features are worthwhile, and which are simply marketing gimmicks.

First, glass panes are held collectively in a frame. Glass panes used in double glazing are normally tinted though clear varieties are available. The tint helps to soak up solar radiation so that in the course of the warm summer months, your house is not going to feel like an oven.

The commonest tints are bronze, gray, blue and green. Higher-finish glass panes could employ 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 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 far slower in gases (like the air or argon trapped within the spacer) because the particles not only move freely but are also situated far aside from every other. The impact is improved insulation. Heat does not escape simply from the window. Your private home stays warmer longer.

Sound travels slowest through air and accounts for how 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 internal glass panes. Conventional spacers include dessicant as an added precaution in opposition to condensation.

There are several factors that may have an effect on the overall efficiency 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 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.
