Have you heard about ecological roofing or know what the advantages are ? A roof protects the building from rain, storms, in addition to cold. So far as an ecological roof is involved, it's a special structure that can allow a range of plants to grow as part of it. There is a green roofing trend occurring in Australia and quite a lot of buildings now own ecological roofs.
Roof Structure
In this roof design, the covering consists of a number of layers and in addition each layer has it's own purpose. The major layer acts as the water-resistant sealing to prevent water leaks. There are a number of materials used to build this membrane, like a metal tray or a synthetic material.
The next level provides drainage and lets the water drain off the roof. It is very important to protect the water-proof layer from getting punctured by the plant roots and the protection layers do this in ecological roofing. The topmost layer is the growth medium, in which the bed is made to for plants to grow in.
There are three main categories and these are extensive roofs, intensive roofs plus other bio-diverse roofing.
Extensive green roofs (eco-roofing) promote the growth of only mosses plus small grasses. For this there's just a thin growing bed needed, that can carry the weight of around 60 to 150 kilogram per square meter. Extensive roofs are the cheapest of the green roofing options.
Usually for planning roof-top gardens and also green parks, the intensive eco-roof method is used. Flowers, shrubs and various medium-sized trees get grown in this roof style. For the growth of trees and plants, a more substantial soil bed has to get maintained, to endure a pressure of at least 180 to 500 kilogram per square meter.
On the other hand, a natural ecosystem is allowed to grow on a bio-diverse green rooftop. The thickness of the soil may vary toallow for a wide range of plants. Seeds and plants are encouraged to grow naturally on the top of this roof type without planned intervention. This sort of roof is basically aimed to deliver a natural environment for endangered species and is not as common for household roofs.
Some Advantages
Adopting green roofing will help you change unattractive roofs into a pleasing and refreshing one. Not just this, but eco-roofing can offer a mix of other benefits in addition. Normal roofing procedures may fail to save the surface of your roof from the damaging effects of UV rays. But the soil on green roofs acts as a protective shield, safeguarding your roof from harmful UV light-rays.
This eco roofing delivers a thermal effect which keeps the temperature of your house even over seasonal changes. As a result, the need for air-conditioning can be reduced, saving energy as well as protecting the environment.
Green roofs in addition absorb a lot of rain and later send it back to the environment, instead of simply draining it out. Considering the environmental and financial benefits it offers, green roofs can be a first-class option.
