For those who live in an space the place winters are particularly lengthy, you will discover it advantageous to switch from traditional home windows to double glazed units. There are a lot of benefits associated with the latter: Double glazed windows are more energy-efficient and harder to break. They also do a greater 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 – but it’s value understanding the science that can assist you to make higher selections about which options are worthwhile, and which are simply marketing gimmicks.

First, two glass panes are held together in a frame. Glass panes used in double glazing are normally tinted although clear varieties are available. The tint helps to soak up solar radiation so that in the course of the warm summer season months, your house will not feel like an oven.

The commonest tints are bronze, grey, blue and green. Higher-finish glass panes may 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 hole is key to reducing heat loss and noise. Heat will always move from higher to decrease 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 within the spacer) because the particles not only move freely but are additionally located far apart from each other. The impact 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 parties without disturbing the neighbours.

Finally, the barrier is sealed to stop the entry of outside air and to avert moisture build-up in the inside glass panes. Typical spacers include dessicant as an added precaution towards condensation.

There are several factors that may have an effect on the overall efficiency of double glazed windows. These embody the kind of window frame used, the thickness of the glass and the house between them.

Regardless of the variables, all double glazed home 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 2 panes of glass is an air or gas-filled barrier that works to reduce heat loss and regulate heat gain.
