And ventilation outputs

The installation of a roof ventilation system allows you to remove water vapor from the room coming upstairs, drop the temperature on the total surface of the roof and prevent the occurrence of ice on cornice overhangs, as well as reduce the direction of heat accumulated under the trim from the exposure of the sun. An important link in the entire roofing system is ventilation consisting of several elements, which include passing elements and ventilation outputs. To maintain the tightness of especially complex parts of the roof, passing elements are designed, such as television antennas, yields of chimney pipes. Such ventilation outputs are facing the withdrawal from the premises of the spent air forced or naturally. The principle of this action is based on the use of air flows occurring with a pressure difference. To evade the introduction of snow, water and better traction, the products from the roof ridge are installed at a minimum distance. Ventilation outputs are also divided into the following types: ridge, which are designed for roofs with an angle of about 27 ° and pitched, designed for roofs with a slope of up to 20 degrees.
