Double glazing is when two panes of glass are combined into a single window system. The system is designed to create a sealed gap between the two panes filled with air or an inert gas like argon. This acts as an extra layer of insulation, increasing the thermal resistance and reducing the amount of heat escaping through your windows in winter. In summer, the effect is opposite, keeping heat out and helping to keep the interior cool.
Since windows are responsible for a significant proportion of a building’s heat loss, double glazing dramatically improves your energy efficiency. Since less heat is lost to the outside environment, less energy is required to keep your interiors warm. Likewise, in summer less energy is required to keep the interior cool.
Not only will you save on your energy costs, but by lowering your reliance on heating and cooling systems you will also reduce your carbon footprint.
Double glazing also helps to reduce instances of condensation on the inside of your windows. While this helps with energy efficiency, it also reduces the risk of moisture damage to your window sills and frames.
Double glazing has the additional benefit of improving sound insulation around your home. The extra pane of glass and layer of gas can help to block out ambient noise from outside, like human voices and traffic noise.
Finally, double glazing can help to bolster your home security. The additional pane of glass means that your windows are harder to break, which toughens up one of the more vulnerable areas of your home.
Whichever way you look at it, double glazing is a sensible investment for your home or business.
