Skylight / July 11, 2018 / Nicolas Charlebois
Tubular skylights An alternative to the conventional skylight which looks like a window in your roof is the tubular skylight. The tubular skylight is a roof-mounted dome which collects natural light and delivers it to the room below. It is less expensive than the conventional skylight because it is designed to fit between roof and ceiling framing eliminating the need for structural modifications. You will commonly see these used in bathrooms hallways and closets but they can be used in any room of your house. The average tubular skylight ranges in size from 10 - 21 inches in diameter which lights a 100-600 square foot interior space.
There must be a clear opening in the area where the skylight is to be placed. A skylight that faces the East lets in plenty of morning sunshine while one that faces the West brings lets in the afternoon sunshine. It is important to know the amount of light and the type of light your skylight lets in. Afternoon sunlight can become uncomfortably hot if you live in a warm and dry place. The size of the room also has a bearing on the effectiveness of the skylight on your roof. If the room is small your choices are severely limited as skylights are best suited for large rooms. If you still want a skylight for a small room it is best to opt for an elegant pyramid skylight. This gives the illusion of space.
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.
