Quality double glazing is distinct from other energy-efficient technologies that can only ineffectively minimize heat gain or loss—or combined. By regulating the movement of hot or cold air between the two windows, its special insulation capabilities help keep the house warmer in the winter and cooler in the summer. Not only does this keeps the house pleasant all year round, but it also lessens the need for artificial heating and cooling.

Double-glazed windows have become more and more common during the last quarter of the 20th century. Two glass panes with argon gas wedged between them make up these windows. Through its role as a heat-insulating layer, the gas helps the windows in their effort to reduce temperature dispersion. The window’s main component is the insulated glass unit (IGU) or double-glazed sealed unit, which is housed in a frame constructed of wood, aluminum, or uPVC. Between two glass sheets, a spacer bar produces an air gap that is later filled with an insulating gas, such as Xenon, Krypton, or Argon. In the UK today, six out of ten households have double-glazed windows.
