The green roof is an architectural concept based around sustainable development. This type of flat roof,
with suitable thermal insulation and a bituminous waterproof membrane, carefully prepared to have a substrate
and vegetation across the whole surface, is known either as:
or INTENSIVE.
Extensive vegetation
An easy process to implement because the plants only use a small amount of soil (a substrate with a
composition that is essentially mineral-based and a thickness of between 6 and 10 centimetres). Naturally,
these are species that have little need for water, care and nutrients. They normally grow in arid and uncultivated
places and do not need to be pruned or mown.
