Skylight / July 7, 2018 / Arnou Gabriaux
For example the optimum slope for a south-facing skylight in Columbus Ohio at 40º North latitude is 45º to 55º. Every skylight has a "shaft" which governs how much light is admitted into the room below. If all four sides are flared then the light is spread over a wide area. If your skylight has a shaft with perpendicular sides the light is focused straight below. If your skylights shaft is flared on only one or two sides then the light is sprayed in the flared direction. Ventilation If you wish you can have a skylight which also provides ventilation as well as light to your room. This allows you to release the hot air which collects at your ceiling.
Some people in an effort to let in plenty of light choose the biggest skylight they can afford. But bigger is not always better when it comes to choosing skylights for your home. The size of the skylight should not be more than 5% of the floor space if there are other windows in the room. It should be less than 15% of the floor space if there are few windows in the room. Unlike commercial buildings where structures are huge there is only so much that a room within the house can take. So choose skylights that suit the size of the room. Style: Although most skylights are rectangular these are available in a variety of sizes shapes and colors.
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.
