Skylight / July 9, 2018 / Delphine Demers
A skylight might seem like the easiest option for rooms that are cramped dingy and dark. In many cases it is but only if the right kind of skylight is combined with the right type of roof. Fixing a skylight on the roof is not like placing a window in the wall. Most of us think only of the interior when we fix skylights. But did you know that your first priority should be your roof followed by the positioning of the skylight on the roof? The shape of the roof is a vital to the selection of skylights. There are different skylights for sloped roofs and different skylights for flat roofs. Incorrect installation can lead to problems in the future.
Before installing a skylight in your home you need to carefully evaluate what type of skylight will work best for you considering your specific requirements and how to install it in a way that it improves your homes energy efficiency. Its a sensible idea to evaluate the energy performance ratings of skylights based on the climate that you live in and the architectural design of your home. In the U.S. you can find labeled energy-efficient skylights which tell you the minimum energy performance rating criteria by climate. The physical dimensions of the skylight also greatly affect the lux level and temperature of the space it is being used for.
If the room you intend to illuminate with the skylight has an open ceiling with no attic space above you can install the skylight without needing to construct a light shaft. This is by far the simplest installation and it offers the maximum amount of light and a view of the sky. For ceilings with an attic space above a light shaft must be constructed that connects the skylight to the room. Skylight shafts take one of three forms: Straight in which the shaft drops vertically from the roof to the ceiling and is the same dimension as the skylight itself. This type is the easiest to construct but because of its offset angle relative to the skylight offers the least amount of light.
