Green roof slab thickness.

Green roofs reduce the temperature of the building and the surrounding air in multiple ways. The plants in a green roof absorb water through their roots and then use surrounding heat from the air to evaporate the water while some roofs can reach temperatures of up to 90 f in the summertime these two features can allow. It is common practice to use the term extensive to describe green roofs that are very thin and will only support hardy drought resistant vegetation such as sedums herbs and perennials. There are two types of green roof.

Intensive roofs which are thicker with a minimum depth of 12 8 cm 5 1 16 in and can support a wider variety of plants but are heavier and require more maintenance and extensive roofs which are shallow ranging in depth from 2 cm 13 16 in to 12 7 cm 5 in lighter than intensive green roofs and require minimal maintenance. The entire thickness of the layer is usually between than 6 to 15 cm. Intensive green roofs have a higher weight and require a minimum soil thickness of at least 30 cm compared to the 5 12 cm of the latter. They provide shade to the top of a building evapotranspiration.

Extensive green roofs are principally created for their ecological advantages. Intensive to describe green roofs that are thick enough.
