If you happen to live in an area the place winters are particularly lengthy, you will find 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-environment friendly and harder to break. Additionally they do a greater job of reducing noise.
So, how exactly does double glazing work? Opposite to what many individuals think, the precept behind the technology is fairly easy – but it’s value understanding the science that can assist you to make better choices about which options are worthwhile, and which are merely marketing gimmicks.
First, two glass panes are held collectively in a frame. Glass panes used in double glazing are often tinted although clear varieties are available. The tint helps to soak up solar radiation in order that throughout the warm summer time months, your house will not feel like an oven.
The most typical tints are bronze, grey, blue and green. Higher-end 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 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 apart from each other. The impact is improved insulation. Heat does not escape simply from the window. Your home 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 great way to host late-night 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 interior glass panes. Typical spacers contain dessicant as an added precaution towards condensation.
There are a number of factors that can affect the overall effectivity of double glazed windows. These embrace the kind of window frame used, the thickness of the glass and the house between them.
Regardless of the variables, all double glazed windows operate under the same basic principle. Traditional home windows utilize only one pane of glass, whereas double glazing makes use of two. Between the two panes of glass is an air or gas-filled barrier that works to reduce heat loss and regulate heat gain.
