Green Roof Protection Fabric

Green roof components can include.

Green roof protection fabric.

The 6 slotted triangle shape is used beneath the aggredrain layer and allows for water to flow freely. It protects the waterproofing and the insulation of the green roof. Aggredrain is most commonly used at a 1 minimum depth over a moisture retention mat grs mrm 14 or grs mrm 30. Green roof systems of this type are drained by a multi layer fabric mat called a drainage mat that combines soil separation drainage and protection functions.

It is able to absorb 3 6 l m moisture depending on the product. Root barriers are often used in green roofs to provide some protection to the waterproofing from invasive stolons rhizomes and from woody roots from trees and shrubs. The most common root barriers used are thin polyethylene sheets laid over the waterproofing membrane. A filter fabric layer on top should separate the aggredrain from the growing media.

Root barrier lower filter fabric water retention mat upper filter fabric growing medium and sedum. A green roof system consists of two major groups of components. This geotextile is made of polyester fibres a mixture of mechanically reinforced fibres and regenerated polyester and polypropylene. Compared with green roofs systems using drainage plates or granular drainage this system is the fastest to install and creates the thinnest and lightest green roof assembly.

These may not be required if the waterproof membrane is certified as root resistant. The green roof solutions drainage conduit is a stainless steel channel for use with the aggredrain system.
