Skylight / November 15, 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.
This heat gain can be minimized by installing your south-facing skylight in the shade of deciduous trees or adding a moving window covering. Skylights come in all shapes and sizes. Its size greatly affects the illumination level and temperature of the space below. As a rule of thumb the size of a skylight should never be more than 5% of the floor area in rooms with many windows; and no more than 15% of the rooms total floor area for spaces with few windows. Dept. of Energy. Glazing Like windows skylight manufacturers use different types of glazing to improve their energy efficiency. The glazing comes in three different forms. Plastic glazing - This type of glazing is usually inexpensive and less likely to break than other glazing materials.
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.
