Skylight / July 12, 2018 / Odo Vaillancour
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 installed badly however they can do a great deal of damage. Many people dont realize how easily that damage can be avoided by purchasing a replacement skylight instead of giving it up altogether. A skylight might be detrimental to a house in many different ways. They require flashing when installed and without proper flashing of aluminum or some other sturdy material the light will leak. Rain and other forms of moist weather will find its way into the house itself. Roof design is very important when choosing and installing a skylight. It is another reason why skylights fail after awhile. The angle or tilt of a roof and the angle at which the skylight is set will determine how strong and supported the light is.
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.
