If you happen to live in an area where winters are significantly long, you’ll discover it advantageous to switch from traditional windows to double glazed units. There are numerous benefits associated with the latter: Double glazed windows are more energy-efficient and harder to break. Additionally they 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 fairly easy – however it’s price understanding the science that can assist you to make higher selections 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 although clear varieties are available. The tint helps to soak up solar radiation in order that during 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-finish glass panes could 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 lower temperature. In solids (like glass), this occurs very quickly because the particles are tightly packed.
Heat transfer is far slower in gases (like the air or argon trapped in the spacer) because the particles not only move freely however are additionally located far aside from each other. The effect is improved insulation. Heat doesn’t escape simply from the window. Your house stays warmer longer.
Sound travels slowest through air and accounts for the way double glazing can keep noise ranges down. Additionally, some spacers come with foam padding designed to soak up echo and muffle sound. This is a superb way to host late-night events without disturbing the neighbours.
Finally, the barrier is sealed to forestall the entry of outside air and to avert moisture build-up within the inside glass panes. Typical spacers comprise dessicant as an added precaution against condensation.
There are several factors that may affect the overall effectivity of double glazed windows. These include 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 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-filled barrier that works to reduce heat loss and regulate heat gain.
