Double Glazing
Double Glazing is a method of window construction where two panes of glass are sealed together with a space between them, usually filled with air or special gas. This creates better insulation for buildings compared to single-pane windows. When candidates mention this term, it typically means they have experience installing, maintaining, or selling these energy-efficient window systems. Similar terms include 'insulated glass units' or 'IGUs.' Double glazing is a fundamental concept in modern construction and is important for both residential and commercial buildings.
