The Skylights industry, classified under SIC Code 1761, involves the installation, repair, and maintenance of skylights in residential, commercial, and industrial buildings. Skylights are windows installed on the roof of a building to allow natural light to enter the interior space. This industry is an important part of the roofing, siding, and sheet metal work sector, as skylights require specialized knowledge and skills to install and maintain. Skylights come in a variety of shapes and sizes, including fixed, vented, tubular, and custom designs. They can be made from different materials such as glass, acrylic, and polycarbonate. The installation process involves cutting a hole in the roof, framing the opening, and sealing the skylight to prevent leaks. Skylights can also be retrofitted into existing roofs. The Skylights industry is driven by the demand for energy-efficient and sustainable building solutions. Skylights can reduce the need for artificial lighting, which can lower energy costs and improve indoor air quality. They also provide natural ventilation, which can reduce the need for air conditioning and improve occupant comfort.
