The primary advantage of using insulated glass units is energy efficiency. Buildings equipped with IGUs can maintain a more consistent indoor temperature, reducing the reliance on heating and cooling systems. Consequently, this leads to lower energy bills and a decreased carbon footprint. The use of IGUs also enhances sound insulation, making them ideal for urban environments where noise pollution is a concern. The multiple panes, along with the airspace, significantly dampen sound transmission, creating a more peaceful indoor atmosphere.
