Skylights are a great way to let natural light into a building, but they can also be a major source of heat gain in the summer. Facade skylight detailing is a process that is used to ensure that the skylight on the facade of a building is properly installed and functioning. The process includes inspecting the skylight and the surrounding area to make sure that it is properly sealed and that there is no water infiltration. The detailing process also includes checking the flashing around the skylight to make sure that it is properly installed and sealed. If any problems are found, the detailing process will include fixing those problems.A well-detailed skylight can reduce the heat gain by up to 50%. There are a few things that need to be done to detail a skylight properly. First, the flashing needs to be properly installed and sealed. The flashing is the metal or plastic material that is used to seal the skylight to the roof. If the flashing isn’t installed properly, water can get into the building and cause damage. The second step is to seal the joints between the skylight and the roof.
