Window glazing refers to the process of installing glass in windows and doors. It involves fitting glass panes into frames to create a barrier against weather elements while allowing light to enter. Glazing can be single, double, or triple, depending on the number of glass layers used, which affects insulation and energy efficiency. In addition to providing visibility and protection, window glazing can enhance a building's aesthetic appeal. Different types of glass, such as tempered or laminated, can be used for safety and durability. Proper glazing techniques are essential for ensuring that windows are energy-efficient and long-lasting.
