Should you live in an space the place winters are particularly long, you’ll discover it advantageous to switch from traditional windows to double glazed units. There are various benefits related with the latter: Double glazed windows are more energy-efficient and harder to break. In addition they do a greater job of reducing noise.
So, how exactly does double glazing work? Contrary to what many individuals think, the precept behind the technology is fairly simple – but it’s worth understanding the science that can assist you to make better decisions about which features are worthwhile, and which are merely marketing gimmicks.
First, glass panes are held collectively in a frame. Glass panes used in double glazing are usually tinted though clear varieties are available. The tint helps to soak up solar radiation in order that through the warm summer time months, your house is not going to feel like an oven.
The commonest tints are bronze, gray, 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 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 transfer is way slower in gases (like the air or argon trapped in the spacer) because the particles not only move freely however are also located far other than every other. The effect is improved insulation. Heat doesn’t escape simply from the window. Your own home stays warmer longer.
Sound travels slowest via air and accounts for how 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 events without disturbing the neighbours.
Finally, the barrier is sealed to stop the entry of outside air and to avert moisture build-up within the inside glass panes. Standard spacers include dessicant as an added precaution against condensation.
There are a number of factors that can 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 area between them.
Regardless of the variables, all double glazed home windows operate under the identical primary principle. Traditional home 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-crammed barrier that works to reduce heat loss and regulate heat gain.
