Roof Pond Definition

Flat roofs are an ancient form mostly used in arid climates and allow the roof space to be used as a living space or a living roof flat roofs or low slope roofs are also commonly found on commercial.

Roof pond definition.

The water will then sit and create a pond the longer water sits on a roof the more likely it is to cause damage over time. Ponding water accelerates the deterioration of many materials including seam adhesives in single ply roof systems steel equipment supports and particularly roofing asphalt. Therefore they can be utilized in efforts towards the goal of carbon neutral design. This review suggests that in some cases roof ponds can provide year round thermal comfort while reducing demand for active heating and cooling systems.

A pond of water on a roof structure that cools a building by evaporation. A flat roof is a roof which is almost level in contrast to the many types of sloped roofs the slope of a roof is properly known as its pitch and flat roofs have up to approximately 10. The roof ponds of contained water are the heating and cooling unit. In the building trades the acronym tpo stands for thermoplastic polyolefin a material originally developed for pond liners and used extensively for roofing since 1989 it s a single ply membrane made from a polymerized combination of polypropylene and ethylene propylene rubber that can be attached to a roof with adhesive or with mechanical fasteners.

The roof pond approach brings the differing building aspects of a building roof ceiling heating and cooling system and heat distribution does away with ducts into one system. Overall 19 roof pond cooling and 4 roof pond heating systems were identified. Because the water increases the thermal mass of the building it also increases the gain in solar energy storing the absorbed energy during the day when it is abundant for later use. Ponding is the typically unwanted pooling of water typically on a flat roof or roadway.

When drainage fails water will run to low points in a flat roof. The roof ceilings of the building act as the structural support for the roof ponds. An insulated roof pond with materials such as polystyrene panels is placed over the roof and filled with water up to a certain level average water depth in the reviewed papers was 15 cm. Well it s not as fun as it sounds.

Leaks from cooler lines to structural issues building a flat roof can bring considerable advantages for your commercial roof primarily in providing more interior space. So what is roof ponding.
