Domed rooflights are a type of roof window with a curved, dome-shaped surface, usually made from durable polycarbonate. They are an effective solution for bringing more natural light into a space, often used in flat-roofed areas of a building. The shape of the dome is not just for aesthetics; it also offers added structural strength, and the curve helps to disperse sunlight evenly, as well as promoting rainwater run-off.

A dome roof is a curved structure that covers the entire roof area, while a cone roof tapers towards a central point, resembling the shape of a cone. Dome roofs are often used for their aesthetic appeal and the way they evenly distribute natural light entering the space. Cone roofs, on the other hand, offer a distinctive profile and are typically used to cover smaller areas such as towers or roof lanterns. Both roof types provide unique architectural details and can enhance the character of a building.

Roof window domes can be an excellent choice, especially if you are looking to bring more light into a flat-roofed area. They offer a stylish solution that not only allows daylight to flood in but also adds an architectural feature to the roof. The domed shape is effective at dispersing light throughout the room and has the added benefit of shedding water and debris more easily than flat windows, reducing maintenance requirements and enhancing the longevity of the installation.

Dome rooflights are a popular choice for flat roofs and come in various types to suit different needs. The common types include single skin for unheated spaces, double skin for improved thermal efficiency, and triple skin for superior insulation. Additionally, some dome rooflights offer ventilation options and can be designed to open manually or electrically for fresh air. They can also be clear, tinted, or opaque to control light and privacy.
