Extensive Green Roof Build Up

Mounds of up to 250 mm as required for increased biodiversity. - 0 x Insulation - I had to put in some thermal insulation because our council building control couldnt calculate the U value for insulation of the living roof - after installing it this is way better than any fibreglass or fibrespan board - so you probably dont need this.

Type of planting depends on depth of the growing medium layer as well as other factors.

Extensive green roof build up.

Each green roof brings back a piece of nature and on some buildings a recreational space can be created for people to enjoy. Extensive semi-intensive and intensive green roofs.

See above Growing medium. Also you need to protect the building structure so this is my recipe for making a living roof. Extensive roofs are thin lightweight roof systems that typically have a planting media measuring 6 to 20 cm deep while heavier thicker green roofs are known as.

Drainage filter and vegetation layer. Extensive green roofs are generally made up of a shallow layer 20-100mm of substrate planted with low-growing stress-tolerant grasses mosses and sedum. Extensive Green Roofs An Ecological Alternative to Conventional Surface Protection.

Intensive green roof build-ups over roofs and podiums are designed to be trafficked and should only be installed on flat roofs. EXTENSIVE SUBSTRATE E 6 - 21 cm A substrate with high water storage capacity and good air porosity tailored to extensive multi layer systems. Green roofs or living roofs as they are also known can be classified according to type of usage construction factors and maintenance requirements into three different types.

8 to 20 per square foot. The insulation quality is relatively low and extensive systems always incorporate conventional insulation. 15 to 50 per square foot.

The soil is usually not more than 5 deep and is sometimes contained by a tray system which provides a barrier to excessive growth protects the roof membrane and also interlocks the entire system together to prevent wind damage. Extensive landscaped roofs are an ecological alternative to conventional surface protection or ballast layers such as gravel and pavers.

Each layer needs to fulfil several functions to decrease the height and the weight of the overall build-up. A Bauder green roof combines the finished planting scheme and all its supportive components with a high quality and secure waterproofing system to give you the best results every time. Extensive green roofs are generally made up of a very thin layer of soil or other planting medium with shallow-root plants like sedum mosses and grasses.

Green roofs are one of the most effective ways to reduce the ambient air temperature in urban areas. These lightweight systems require little maintenance. Any large slope or flat roof thats hard to reach makes a great area for this kind of vegetation as nature will take care of itself.

Planting and Waterproofing The build-up heights and weights will be dependent upon the type of planting specified however as a rough guide 300 to 1500mm are the typical depths and weights could be in the region of 400kg to over a tonne per sqm. For a conventional roof. The basic build up of a green roof is three layered.

Extensive Green Roofing systems consist of lightweight naturalistic planting that provides extensive plant cover with minimal maintenance and a wide range of benefits including. They are lightweight and have a shallow build-up height. With an extensive green roof vegetation is thinner 16 to five inches thick and lighterwith appropriate plants that will make them low-maintenance and self-sustaining.
