How Does Double Glazing Work?
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 a lot of benefits associated with the latter: Double glazed home windows are more energy-environment friendly and harder to break. They also do a better job of reducing noise.
So, how exactly does double glazing work? Contrary to what many people think, the principle behind the technology is fairly simple – however it’s value understanding the science that can assist you to make higher selections about which features are worthwhile, and which are simply marketing gimmicks.
First, two glass panes are held collectively in a frame. Glass panes utilized in double glazing are often tinted although clear varieties are available. The tint helps to absorb solar radiation so that throughout the warm summer season months, your house is not going to feel like an oven.
The most typical tints are bronze, gray, blue and green. Higher-end glass panes could make use of a mix of reflective, anti-glare and heat-absorbing technologies.
Second, a barrier of air or gas is maintained between the two 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 switch is way 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 every other. The impact is improved insulation. Heat doesn’t escape easily from the window. Your house 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 soak up echo and muffle sound. This is a good way to host late-night time events without disturbing the neighbours.
Finally, the barrier is sealed to stop the entry of outside air and to avert moisture build-up in the interior glass panes. Conventional spacers comprise dessicant as an added precaution in opposition to condensation.
There are a number of 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 home windows make the most of only one pane of glass, whereas double glazing makes use of two. Between the two panes of glass is an air or gas-crammed barrier that works to reduce heat loss and regulate heat gain.
