FLEX 80 TPO PLUS DATA SHEET
(REINFORCED, THERMOPLASTIC POLYOLEFIN MEMBRANE)
PRODUCT DESCRIPTION
The Flex 80 TPO Plus polyester reinforced thermoplastic polyolefin (TPO) roofing membranes are designed
for use in mechanically fastened and adhered roofing systems. The Flex 80 TPO Plus membrane is
manufactured in widths of 5’ and 10' for economical installations. Flex 80 TPO Plus membranes offer the
proven weathering resistance of rubber (derived from its high ethylene propylene rubber content) combined
with the thermoplastic properties of polypropylene. The combination results in a roofing membrane with hot
air welded seams and the durability of EPDM roofing membranes. The Flex 80 TPO Plus membranes
polyester reinforcement allows for structural movement with no splitting or cracking. The Flex 80 TPO Plus
membrane is also highly impact and puncture resistant. The specially formulated membrane offers excellent
resistance to solar UV and chemical exposure as well as remaining flexible in cold temperatures.
USE
Flex 80 TPO Plus membranes can be installed in new, reroof (tear-off) and recover roof constructions. In
recover construction, if the existing roof is structurally acceptable, the Flex roof system can save the cost of
disposing of the original roof system. Flex 80 TPO Plus membranes can be installed directly over layers of
approved roof board insulation. The membrane is secured to the deck using an approved fastening system
utilizing methods that have been independently tested for wind uplift. The Flex 80 TPO Plus membranes are
true thermoplastics, therefore all seams is sealed by the hot air welding method creating a seam as strong as
the original membrane.

INSTALLATION
The roofing system must be installed by an authorized Flex Roofing Systems TPO applicator. The Flex
applicator must inspect the area to be roofed to determine if the installation of a Flex Roof System is
acceptable. The substrate must be clean, smooth, dry, and free of flaws, debris and other irregularities.
Follow Flex Specifications and NRCA recommendations for installation of wood nailers around perimeters
and penetrations. Install approved insulation according to Flex’s standard fastening requirements or
applicable code whichever is more stringent. The membrane is mechanically attached using the disk and

fastener in the seam method. Fastener spacing increments are determined by the projects specification
criteria and or printed guide specifications. For adhered systems, the membrane is laminated to the
appropriate substrate using Flex Bonding Adhesive. All seams are completed by the hot air welding method.
Contact the Flex Technical Service Department for the specific design requirements and installation
procedures for these two systems.
