Green Roof Filter Fabric

We re pleased to introduce our new j drain eco fabric.

Green roof filter fabric.

Bmi canopia filter fleece. The grs ff35 has a high flow rate of 150 gallons per minute per square foot. Density as per astm d3776 8 oz yd2. Root resistant filter fabric serves to prevent root penetration into the underlying roofing if it is not root proof.

Optigreen separation fabric weighs approximately 200 g m2 6 oz yd2. Optigreen separation fabric is a non woven geotextile made from recycled polypropylene. Green roof solutions has a 3 5 oz filter fabric ff35. Filtration layers are required in green roof systems as a separation and containment layer to limit the amount of fine particles reaching the drainage layer and rainwater outlets.

Polypropylene fibers are needled to filter fabric for a stable network that retains dimensional stability relative to one another. Our greenroof root resistant filter fabric is 100 post consumer recycled nonwoven polyester and are manufactured using post consumer recycled material pcr chip. They are also useful for encapsulating other components such as telescopic drainage tubes to reduce the amount of fines getting into them. Green roof solutions has a 3 5 oz filter fabric ff35.

Puncture resistance as per astm d4833 130 lb. Since it is significantly less likely to clog than common filter fabrics it is ideal for separating green roof soils from underlying drainage media or drainage plates. The function of the existing roofing is completely preserved. Strong enough and adequate puncture resistance to withstand stresses of installing other layers of the green roof.

Filter fabric generally needle punched non woven polypropylene geotextile with the following qualities. A filter fleece separates the drainage layer from the roof garden substrate in a green roof structure. The fabric is resistant to degradation from uv exposure as well as the. It s green even before its green our green vision is now even greener.

Beneath the growing media and above the drainage system the filter fabric keeps the media from clogging up the drainage while allowing water to flow freely. An important consideration with filter fabric is the promotion of the flow rate while preventing media runoff. The green roof does make sure that the durability of the roofing is extended. Filter fabric is designed to separate the growing media from the drainage system on vegetative green roofs.

It prevents small soil particles from filling the drainage layer and so the water buffering function of the drainage layer remains intact for longer. A layer of filter sheet will prevent substrate dropping into the drainage layer. An important consideration with filter fabric is the flow rate while preventing media runoff.
