Skylight / July 8, 2018 / Baptiste Allain
Skylights let in outdoor light cutting down on both heating and electricity costs. When a skylight is designed and installed properly it can light an entire room provide heat and improve the appearance of your home or business. These are just some of the basic benefits to using skylights; you could even look into utilizing the solar power from your skylights in different ways to live more eco-friendly. No matter what type of home or business ceiling thickness you have there is a skylight design that will work for you. For buildings with thick ceilings attics or multi-storied buildings often utilize tubular skylights. For the layperson the easiest way to describe tubular skylight design is a long tubular channel with a collector at the top and a diffuser at the bottom that will illuminate an area between 75 and 150 square feet per skylight.
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.
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.
