Skylight / July 8, 2018 / Baptiste Allain
Skylights are usually covered with translucent or transparent material to allow light to pass through while also protecting from extreme weather conditions. A Skylight is a great way to allow more light into your home through a flat or sloped window built into the roof structure for daylighting. Adding a skylight can almost immediately open up any room and make it lighter and brighter adding a sunny airy feeling. Skylights come in many styles and designs. They can be rectangular oval triangular or any odd shape and are perhaps the most beautiful way to enjoy the rain as you see it fall over your head. Windows cannot recreate the drama and magic that skylights can add to your house.
It is recommended that the skylight size should never be more than five percent of the floor area in rooms with many windows and not more than fifteen percent of the rooms total floor area for spaces with very few windows. Skylights on north-facing roofs provide cool illumination while east-facing roofs provide maximum light and heat in the morning. West-facing skylights provide afternoon sunlight and heat. South-facing skylights provide more passive solar heat than any other location. Skylights are an excellent way to bring more natural light into your home. Just one skylight can dramatically transform your room by adding 30% more natural light than a window. This helps you save energy and makes your home warmer during the winter.
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.
