Skylight / July 8, 2018 / Baptiste Allain
Solar heat control glazing - Manufacturers use various glazing methods to reduce the impact of summer time solar heat gains and winter time heat losses. These come in the form of heat-absorbing tints double and tripled paned skylights and low-emissivity coatings. Slope When your window professional installs your skylight one of the factors they will take into consideration is the slope. The slope or tilt of the skylight affects the amount of solar heat gain. A low slope on your skylight admits more solar heat in the summer and less in the winter which is the opposite of the effect you are trying to achieve As a rule of thumb you want to achieve a slope equal to your geographical latitude plus 5 to 15 degrees.
This is ideal for cubicles or small offices even restrooms. The places where tubular skylights are most effective are in the bottom floor of a multi-story building in order to light the space with natural sunlight warehouses private offices or to prevent heat loss and for solar gain. The installation of tubular skylights requires a professional installer who can work with the thickness of your ceiling and angles to get the most out of your skylight. The top panel of the skylight will be affixed to your roof with the channel running through the ceiling completely hidden from sight with the bottom window attached on the visible area of the ceiling.
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.
