Green Roof Aeration Layer Material

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.

Green roof aeration layer material.

Cup style drainage sheets should be overlapped to eliminate the possibility of gaps being created between sheets. 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. 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.

It is made of a filtration veil and the polyamide monofilament fibre network layer. What is a green roof. 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. 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.

Root barrier drainage layer moisture resistant insulation aeration layer moisture retention layer reservoir layer. The green roof solutions drainage conduit is a stainless steel channel for use with the aggredrain system. Our root barriers are constructed of virgin polyethylene with a carbon black additive. It should have good consistent drainage and aeration with a structure that.

To better understand the full use of a green roof system we have broken down the layers here. Seams are overlapped from 6 12 and are taped to provide a continuous layer between the green roof and the roof membrane waterproofing. 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. Drainage protection filtration layer it is used for lightweight green roofs terraces and has many functions.

Root barrier the root barrier is the system that avoids the membrane underneath from being pierced and penetrated by roots ensuring that the system can remain. Protection drainage and filtration. The 6 slotted triangle shape is used beneath the aggredrain layer and allows for water to flow freely. Drainage is installed as a continuous layer over the entire surface of the green roof.

Green roof growing medium is composed of mineral aggregates and only a small amount of organic material. Other plastic drainage types should have adjacent sheets butted together. 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.
