How does double glazing work?


If you live in an area where the winters are particularly long, you will find it advantageous to switch from traditional windows to double glazing. There are many benefits associated with this: double-glazed windows are more energy efficient and more difficult 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 of technology is quite simple – but it is worth understanding science to help you make better decisions about what features are worthwhile and that are merely marketing tricks .

Firstly, Two panes are held together in a frame. The panes used in double glazing are generally colored, although clear varieties are available. The hue helps absorb solar radiation so that during the hot summer months, your home will not feel like an oven.

The most common colors are bronze, gray, blue and green. The top glass panes can use a combination of reflective, anti-glare and heat-absorbing technologies.

Secondly, an air or gas barrier is maintained between the two panes. Called a spacer, this gap is essential to reduce heat loss and noise. The heat always goes from the highest temperature to the lowest. In solids (such as glass), this happens very quickly because the particles are well packaged.

Heat transfer is much slower in gases (such as air or argon trapped in the spacer) as the particles do not only move but are also located Very distant one from the other. Insulation is improved. The heat does not easily escape from the window. Your home stays warmer for longer.

The sound moves more slowly in the air and explains how double glazing can reduce noise levels. In addition, some spacers come with a foam padding designed to absorb the echo and muffle sound. This is a great way to host nightly evenings without disturbing neighbors.

Finally, the barrier is sealed to prevent outside air entry and to prevent moisture accumulation in the interior windows. Conventional spacers contain desiccant as an additional precaution against condensation.

There are several factors that can affect the overall efficiency of double glazed windows. These include the type of window frame used, the thickness of the glass and the space between them.

Independently of the variables, all double glazed windows operate according to the same basic principle. Traditional windows use only one window, while the double glazing uses two. Between the two panes is an air or gas barrier that reduces heat loss and regulates the heat gain.
