3.2.4 Analysis of green roof The green roofs are inclined hills built on the top of stepped structure. This acts as a single plane rather than dividing that into horizontal and vertical planes, thus the transition between them is resolved by the greenery. At this rate the amount of soil used would be much larger, but it has been reduced by forming bulk of the inclined area with foam. This foam bulk massively reduces the weight of the structure above the roof that is soil. The soil layer is placed above the foam layer separated by the drainage layer made from plastic. The soil used is an artificial inorganic lightweight soil made up of a naturally occurring amorphous volcanic glass, perlite, aluminium, potassium, many silicon dioxide and sodium oxides. The benefit of this soil is that it can retain water at higher rate and can be saturated as well when needed.
