How Does Double Glazing Work?
When you live in an area the place winters are notably lengthy, you will see it advantageous to switch from traditional windows to double glazed units. There are lots of benefits associated with the latter: Double glazed windows are more energy-environment friendly and harder to break. They also do a better job of reducing noise.
So, how precisely does double glazing work? Opposite to what many people think, the principle behind the technology is pretty simple – but it’s value understanding the science to help you to make better selections about which features are worthwhile, and which are merely marketing gimmicks.
First, glass panes are held together 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 in the course of the warm summer months, your house won’t really feel like an oven.
The most common tints are bronze, grey, 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 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 switch is far slower in gases (like the air or argon trapped in the spacer) because the particles not only move freely but are also situated far other than every other. The impact is improved insulation. Heat doesn’t escape easily from the window. Your house stays warmer longer.
Sound travels slowest by way of air and accounts for the way double glazing can keep noise levels down. Additionally, some spacers come with foam padding designed to absorb echo and muffle sound. This is a superb way to host late-night time parties without disturbing the neighbours.
Finally, the barrier is sealed to forestall the entry of outside air and to avert moisture build-up in the internal glass panes. Typical spacers include dessicant as an added precaution towards condensation.
There are several factors that may have an effect on 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 home windows operate under the identical basic principle. Traditional windows utilize only one pane of glass, whereas double glazing makes use of two. Between the 2 panes of glass is an air or gas-crammed barrier that works to reduce heat loss and regulate heat gain.
