Skylight domes are architectural elements that are used to provide natural light and ventilation to buildings. They are typically made of glass, acrylic, or polycarbonate and are installed on the roof of a building.

The main purpose of skylight domes is to bring natural light into a building's interior, which can help reduce energy costs associated with artificial lighting. Skylight domes also provide a sense of openness and spaciousness to interior spaces, making them a popular choice for commercial buildings such as shopping centers, museums, and office buildings.

In addition to providing natural light, skylight domes can also be used for ventilation. Some skylight domes are designed to open and close, allowing fresh air to circulate through the building. This can help improve indoor air quality and reduce the need for mechanical ventilation systems.

Skylight domes are available in a variety of shapes and sizes, including circular, square, rectangular, and even custom shapes. They can also be tinted or coated to control the amount of light that enters the building and to reduce heat gain.

Overall, skylight domes are a versatile and practical architectural element that can enhance the functionality and aesthetic appeal of a building.
