Skylight / July 11, 2018 / Nicolas Charlebois
Glass and acrylic or plastic skylights are available. Tubular skylights are relatively new on the scene. The small size allows them it to be used in spaces where full-sized skylights cannot. Hallways bathrooms even closets can accommodate a tubular skylight. They provide a lot of light in spite of their small size. The concept and installation process are basically the same as for a regular skylight except they have an enclosed tunnel of reflective material to reflect the light. They are available in many sizes. The small ones are 10 to 12 inch diameter and the large ones are 24 inches. Flat glass skylights come mounted in a wood or integrated rubber and metal framework and require no additional curb construction.
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.
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.
