Skylight / July 12, 2018 / Odo Vaillancour
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.
Another modern option is to have a replacement skylight with double panes of glass with a layer of argon gas infused in between the panes. New features and options make getting a replacement skylight a more viable option than just shingling over the old one. Remote controls make it possible to open and close a skylight on a whim rather than having to clamber about on ladders. Some skylights can also come with rain sensors so they will close the moment they feel raindrops or too much moisture. These options allow the skylight to vent the house while also protecting it against damage.
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.
