Double Glazed Unit (DGU) comprises of two panes of glass, separated by air or other gas filled space to reduce heat transfer across a part of the building envelope. Glass is a good conductor of heat, so, just a single glazed pane window will not insulate your property very well. Whereas, air is a poor conductor of heat and therefore has superior insulating properties. The air gap between each glass pane is sealed around the perimeter, that helps keep more heat inside the room during the winter and outside during the summer. Most units are manufactured with the same thickness of glass used on both panes.
DGU Glass are manufactured in range of thickness from 3 mm to 10 mm (18″ to 38″) or more in special applications. The glass can be a laminated glass or a tempered glass. The DGU glass will generally be up to five times stronger than ordinary annealed glass depending on the glass type and thickness. These are used when strength, thermal resistance and safety are important considerations. Special applications such as acoustic attenuation or security may require wide ranges of thicknesses to be incorporated in the same unit.
