In order for heat to be saved in the house even more, you can put a special energy -saving glass. In summer, such glass repuls hot sunlight, and in winter they retain complete heat inside. At the same time, a special coating that is applied to such glasses will not in any way affect the transparency and strength of the glass. Such windows, with all their advantages, do not fog at all and accumulate less dust on the surface of the glasses.
