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.
Your sunroom manufacturer will probably recommend that if you expect your sunroom to see regular use you hook it up to your homes heating and cooling system. Any occasionally-used however can be constructed with an independent climate control system. Designing Your Sunroom When you are in the designing phase of your sunroom project your sunroom manufacturer will need information about the sun exposure of the location where the sunroom will be located. Knowing the sun exposure will let your sunroom manufacture determine the best kind of high performance glass to install in your sunroom. While your sunroom manufacturer will undoubtedly have a large collection of standard sunroom designs from which you can choose most sunroom manufacturers will be happy to create a custom design.
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.
