PROTECTED | INVERTED MEMBRANE
Job Title
A protected membrane roof is a roof where thermal insulation or another material is located above the waterproofing membrane. Modern green roofs are a type of protected membrane roof. This development has been made possible by the creation of waterproofing membrane materials that are tolerant of supporting a load and the creation of thermal insulation that is not easily damaged by water.
Frequently, rigid panels made of extruded polystyrene are used in PMR construction. The chief benefit of PMR roof design is that the covering protects the waterproofing membrane from thermal shock, ultraviolet light and mechanical damage.[4][5]
One potential disadvantage of protected membrane roof construction is the need for structural strength to support the weight of ballast that prevents wind from moving rigid foam panels or the weight of plants and growth media for a green roof. However, when flat roofs are constructed in temperate climates, the need to support snow load makes additional structural strength a common consideration in any event.
