FIBRANfilter SF32 | PP geotextile
GeotextilesDescription
Flat roof geotextile, not ground geotextile: 140 μm pore size — the largest in its class — for zero water retention above the waterproofing. High-drainage polypropylene geotextile, for inverted and green roofs on all types of building structures.
With a water permeability of V<sub>H50</sub> = 70·10⁻³ m/s and tensile strength T<sub>max</sub> = 7.0 kN/m; used as a separation, filtration or protective layer between materials. It is installed by mechanical fastening or simply laid in place, depending on the type of application. It bears the CE 0751 marking in accordance with ten harmonised European standards and has a projected service life of 100 years.
It bears the CE 0751 marking in accordance with ten harmonised European standards and has a projected service life of 100 years in natural soils.
Overview
