Green Roof Aeration Layer Material

Drainage is installed as a continuous layer over the entire surface of the green roof.

Green roof aeration layer material.

To better understand the full use of a green roof system we have broken down the layers here. A green roof is a layer of vegetation planted over a waterproofing system that is installed on top of a flat or slightly sloped roof. Root barrier drainage layer moisture resistant insulation aeration layer moisture retention layer reservoir layer. It should have good consistent drainage and aeration with a structure that.

Careful selection of material properties such as the water holding capacity and permeability rates of the growing media can enhance annual runoff volume reduction and peak flow reduction capacity of the vegetative roof. The growing media needed to facilitate a healthy green roof will be determined by the type of vegetative growth. Cup style drainage sheets should be overlapped to eliminate the possibility of gaps being created between sheets. Also the green roof drainage layer material is made to be sturdy and strong so that piercing can be limited and that the integrity of the entire program can be retained with ease.

The drainage layer is highly useful for those roofs in which the maximum angle is not more than 10 degrees for roofs which have steeper angles this layer is not required as they provide natural drainage to water with an effective tilt. Protection drainage and filtration. This drainage layer can be constructed using some plastic material or can be designed using some course material such as expanded shade pumice or gravel. Before the growing media is selected there are other layers of the green roof system which play major roles in the functionality of the roof.

Drainage protection filtration layer it is used for lightweight green roofs terraces and has many functions. This is a multi layer green roof system comprising protection fleece drainage layer filter fleece and mineral ri ch plant growing media suitable for drought resistant plants function to provide an ecologically sound protection layer to the roof with all the advantages listed below. It is made of a filtration veil and the polyamide monofilament fibre network layer. This flexible tear and puncture resistant material keeps roots from penetrating the roofing membrane and causing leaks.

A filter fabric layer on top should separate the aggredrain from the growing media. What is a green roof. Our root barriers are constructed of virgin polyethylene with a carbon black additive. The 6 slotted triangle shape is used beneath the aggredrain layer and allows for water to flow freely.

The green roof solutions drainage conduit is a stainless steel channel for use with the aggredrain system. Other plastic drainage types should have adjacent sheets butted together. Green roof growing medium is composed of mineral aggregates and only a small amount of organic material.
