Double glazed windows are made up of two layers of glass separated by a gap, much like a sandwich, and a layer of inert gas or a partial vacuum air is usually trapped between the two window panes. Since removing the air makes the window a poor conductor of heat, it helps to minimise heat loss to the surrounding atmosphere.
These windows can help to keep your house warm, and at the same time, you will be able to save a lot of money on your heating bills. This is very environmental friendly as well.
