Product Data Sheet

FLEX 140N GEOTEXTILE

SEPARATION LAYER

PRODUCT DESCRIPTION

Flex 140N Geotextile is a non woven geotextile composed of polypropylene fibers, which are formed into a stable

network such that the fibers retain their relative position. Flex 140N Geotextile is inert to biological degradation

and resists naturally encountered chemicals, alkalis, and acids.

The Flex 140N Geotextile is installed as a separation or protection layer in Flex Protected Membrane Roof

Systems. It also is used as a protection layer and filtration fabric in Flex Garden Roof Systems and Flex Below

Grade Waterproofing Systems. The Flex 140N has excellent physical and hydraulic properties in addition to high

tensile strength. The Flex 140N provides the required strength and abrasion resistance to protect Flex

Thermoplastic Roofing and Waterproofing Membranes withstanding installation and application stress to create an

effective, long term solution.
