Skylight / July 12, 2018 / Odo Vaillancour
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.
It will also make all the difference for a skylight that doesnt have newer methods for moving condensation away from the window. It is possible that some skylights are suffering manufacturer related defects. Most worthy manufacturers of skylights or replacements will guarantee their product. A new and complete skylight will be sent and installed hopefully at no cost. It will require the same installation techniques as applied with the first but will obviously be better all around. It is often only when installing a replacement skylight that the damage caused by the original is noticed. The moisture damage caused to a roof is often hidden by the shingles and failed flashing around a skylight.
Before installing a skylight in your home you need to carefully evaluate what type of skylight will work best for you considering your specific requirements and how to install it in a way that it improves your homes energy efficiency. Its a sensible idea to evaluate the energy performance ratings of skylights based on the climate that you live in and the architectural design of your home. In the U.S. you can find labeled energy-efficient skylights which tell you the minimum energy performance rating criteria by climate. The physical dimensions of the skylight also greatly affect the lux level and temperature of the space it is being used for.
