Insulating glass units (IGUs) are engineered to regulate the temperature within homes throughout the year. Typically, an IGU comprises two or more glass panes divided by a spacer material and joined at the edge using a sealant. The construction of an IGU creates an air pocket that acts as an insulator, which helps prevent heat loss during colder months and heat gain during warmer months. The use of IGUs can provide energy savings and enhance the comfort level of indoor spaces.
