  • Condensation Control: By offering a seal that prevents warm, moist indoor air from hitting the cold surface of the main window, secondary glazing significantly decreases the risk of condensation and subsequent mold growth.

  3. Hinged Units: These open like a basic door or casement window. They are often used when complete access to the primary window is needed for cleansing or ventilation.
  4. Lift-Out Units: Ideal for windows that are hardly ever opened, these panels can be physically raised out of their frame when maintenance is needed. They provide the most smooth, unobtrusive aesthetic.
