Roof Pond Meaning

Roofing calculator 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.

Roof pond meaning.

Tpo is a type of membrane roofing suitable for flat and low slope roofs. Flat roofs are inherently bad at draining water unlike sloped roofs. 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.

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. Another word for roof. When drainage fails water will run to low points in a flat roof. Roof ponds are an example of this strategy.

Ponding water accelerates the deterioration of many materials including seam adhesives in single ply roof systems steel equipment supports and particularly roofing asphalt. Overall 19 roof pond cooling and 4 roof pond heating systems were identified. Roof ponds can be classified into three broad categories namely dry wet and open cited in. Pond definition a body of water smaller than a lake sometimes artificially formed as by damming a stream.

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. This review suggests that in some cases roof ponds can provide year round thermal comfort while reducing demand for active heating and cooling systems. Roof pond a pond of water on a roof structure that cools a building by evaporation. Ponding is the typically unwanted pooling of water typically on a flat roof or roadway.

Overall 19 roof pond cooling and 4 roof pond heating systems were identified. The roof pond design became popular with the development of the sky thermal system designed by harold hay in 1977. In dry roof ponds water is contained in plastic bags. In the open type water is not contained in plastic bags.
