The answer to 'difference between skylight' is that a skylight and a window are both openings in the roof or ceiling that allow natural light to enter a room, but they have distinct features and use cases. Skylights are installed directly into the roof, while windows are typically installed in the walls.
Skylights are designed to maximize natural light and ventilation, often with a sloped or domed shape to capture more sunlight. They are commonly used in rooms that lack adequate wall space for traditional windows, such as bathrooms, hallways, or open-concept living areas. Skylights can also help reduce energy costs by providing passive solar heating and reducing the need for artificial lighting. However, skylights may be more expensive to install and maintain than windows, and they can be more prone to leaks if not properly installed.
