What are the benefits of double glazed windows?

This added thermal resistance reduces the amount of heat escaping in winter and keeps your home at a more comfortable temperature.

Does double glazing keep a house cool?

Double glazed windows prevent the convection of heat from the outside to the inside of the house. They do this by the empty space in between the two panes of glass that is found in double glazed windows not allowing the heat to pass through. Shutters, blinds and curtains can also keep the house cool during the summer.

How double glazing windows can reduce energy losses from a house?

Hence, the thin layer of air of double glazed windows acts as a heat insulator. In other words, making an extremely thin gap for air to prevent it from circulating properly results in lower heat conduction. So, it reduces the overall heat loss.

How much heat is lost through a window?


The Thermal Envelope
