The answer to 'what is skylight' is a window installed in the roof or ceiling of a home that allows natural light to enter the interior space. Skylights come in a variety of shapes, sizes, and materials, and can provide both functional and aesthetic benefits. They can brighten up dark rooms, reduce the need for artificial lighting, and even help with energy efficiency by allowing passive solar heating.
Skylights are typically made of glass or acrylic and can be fixed (non-opening) or operable (able to open and close). They can be installed in a variety of roof types, including flat, pitched, and curved roofs. Proper installation is important to ensure the skylight is properly sealed and integrated with the roof to prevent leaks and maintain the integrity of the roof system.
