If you live in an area where winters are particularly lengthy, you will find it advantageous to switch from traditional windows to double glazed units. There are many benefits related with the latter: Double glazed home windows are more energy-efficient and harder to break. They also do a greater job of reducing noise.
So, how precisely does double glazing work? Opposite to what many people think, the precept behind the technology is fairly simple – however it’s price understanding the science that can assist you to make better selections about which features are worthwhile, and which are merely marketing gimmicks.
First, glass panes are held collectively in a frame. Glass panes utilized in double glazing are normally tinted though clear varieties are available. The tint helps to soak up solar radiation so that throughout the warm summer season months, your house will not feel like an oven.
The commonest tints are bronze, grey, blue and green. Higher-end glass panes might 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 hole 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 much slower in gases (like the air or argon trapped in the spacer) because the particles not only move freely but are also situated far apart from each other. The effect is improved insulation. Heat doesn’t escape simply from the window. Your own home stays warmer longer.
Sound travels slowest through air and accounts for a way double glazing can keep noise levels down. Additionally, some spacers come with foam padding designed to soak up echo and muffle sound. This is a great way to host late-evening parties without disturbing the neighbours.
Finally, the barrier is sealed to prevent the entry of outside air and to avert moisture build-up in the interior glass panes. Conventional spacers comprise dessicant as an added precaution towards condensation.
There are a number of factors that may have an effect on the overall efficiency of double glazed windows. These include the kind of window frame used, the thickness of the glass and the space between them.
Regardless of the variables, all double glazed windows operate under the identical primary principle. Traditional home 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.
