For those who live in an space where winters are notably long, you will see that it advantageous to switch from traditional home windows to double glazed units. There are numerous benefits associated with the latter: Double glazed windows are more energy-efficient and harder to break. They also do a better job of reducing noise.
So, how exactly does double glazing work? Contrary to what many individuals think, the principle behind the technology is fairly simple – however it’s value understanding the science that will help you to make better choices 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 normally tinted though clear varieties are available. The tint helps to absorb solar radiation so that throughout the warm summer time months, your house is not going to feel like an oven.
The most common tints are bronze, grey, blue and green. Higher-end glass panes may employ a mixture 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 decrease temperature. In solids (like glass), this happens very quickly because the particles are tightly packed.
Heat switch is much slower in gases (like the air or argon trapped within the spacer) because the particles not only move freely but are additionally located far other than each 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 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 good 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 interior glass panes. Typical spacers comprise dessicant as an added precaution in opposition to condensation.
There are several factors that may have an effect on the general effectivity 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 primary principle. Traditional windows utilize only one pane of glass, whereas double glazing uses two. Between the 2 panes of glass is an air or gas-filled barrier that works to reduce heat loss and regulate heat gain.
