Skylight / July 12, 2018 / Odo Vaillancour
Skylights let natural light stream into your home bringing warmth and a feeling of spaciousness. When properly selected and used they can reduce your need for electric lighting and minimize your heating and cooling costs. There are also health benefits to this wonderful sunlight that shines on us. If you lack sufficient sunlight on your skin you will suffer health effects. Thats because the human body was designed to be exposed to sunlight on a frequent basis. We evolved after all under the natural sun not under fluorescent lighting. Our environment was one with plentiful sunlight. Skylights can provide up to 30% more natural light than vertical windows while making a small space seem bigger.
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.
Skylights may seem inexpensive at first glance since a quality 2x4 foot skylight along with a flashing kit costs anywhere from $100 to $400. However you need to consider adding another $3000 for installation costs. That being said you first need to carefully evaluate if installing a skylight is the right thing for your home. Till recently having a roof slope determined if you could install a skylight. Flat roofs or those which were too steep required special tools and techniques. However many of the skylight kits available today include a comprehensive installation kit and procedures which permits it to be installed on all types of roofs.
