Fixed Secondary Glazing
Fixed windows are permanently sealed and do not open, making them ideal for areas where ventilation isn't required. They are commonly used in homes and offices alongside operable windows, providing natural light and unobstructed views without any moving parts.
Fixed secondary glazing offer multiple benefits, including:
Improved insulation
Reduced noise pollution
Enhanced security
Better temperature control
Convenience of operable windows
Fixed Window Installation
Fixed windows are installed as a secondary glazing layer by being mounted on the inside of the existing window frame. This installation creates an insulating air gap between the original window and the fixed secondary glazing, which enhances thermal and acoustic performance.
When used as part of a secondary glazing system, fixed windows contribute to minimising heat loss and reducing noise transmission. Their permanent seal ensures that they work effectively to improve the overall comfort and efficiency of the space without the need for additional moving parts.
