Skylight windows are architectural elements installed on the roof of a building to provide natural light, ventilation, and aesthetic enhancement to interior spaces. These windows are designed to allow sunlight to penetrate directly into rooms from above.

Main features of skylight windows

Fixed Skylights

Fixed skylights are stationary windows that cannot be opened or closed.

Ventilated Skylights

Ventilated skylights are operable windows that can be opened to allow for airflow and ventilation.

Tubular Skylights

Tubular skylights, also known as sun tunnels or light tubes, are small-diameter cylindrical tubes that capture sunlight on the roof and channel it into interior spaces through a reflective tube.

Glazing

Skylight windows feature glazing materials such as glass or acrylic.

Frame

The frame of a skylight window supports the glazing and provides structural integrity.

Flashing

Skylight flashing is a weatherproofing component installed around the perimeter of the window to prevent water infiltration.

Seals and Gaskets

Seals and gaskets are used to seal the joints and edges of skylight windows.

Advantages of skylight windows 

Natural Light

Skylight windows maximise natural light penetration, reducing the need for artificial lighting during daylight hours.

Ventilation

Ventilated skylights provide fresh air circulation and natural ventilation.

Energy Efficiency

Well-designed skylight windows can enhance energy efficiency by reducing the demand for artificial lighting during daylight hours.

Disadvantages of skylight windows 

Heat Gain and Loss

Skylight windows can contribute to heat gain in the summer and heat loss in the winter if not properly insulated.

Water Leakage

Proper installation and maintenance of skylight flashing, seals, and gaskets are essential to prevent water infiltration.

Maintenance

Regular cleaning and maintenance of skylight windows are necessary to ensure optimal performance, longevity, and appearance.
