Why Double Glaze Windows?
Single pane of glass provides poor insulation because glass is a good conductor of heat. This result in heat in your room literally goes out the window. Installing double glaze window can minimize the heat that goes through your window because you have a layer of air trapped between two panes of glass and air is a poor conductor of heat. Double glazing windows also add up to your safety because it is fire resistance.
