Product Data Sheet
FLEX 60 TPO PLUS DATA SHEET
(REINFORCED, THERMOPLASTIC POLYOLEFIN MEMBRANE)
PRODUCT DESCRIPTION
Flex 60 TPO Plus polyester reinforced thermoplastic polyolefin (TPO) roofing membranes are designed
for use in mechanically fastened and adhered roofing systems. The Flex 60 TPO Plus membrane is
manufactured in widths of 5’and 10' for economical installations. Flex 60 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 60 TPO
Plus membranes polyester reinforcement allows for structural movement with no splitting or cracking.
The Flex 60 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 60 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 60 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 60 TPO
Plus membranes are true thermoplastics, therefore all seams are sealed by the hot air welding method
creating a seam as strong as the original membrane.

· White and Tan Flex 60 TPO Plus Membranes are Energy Star® roof products
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, 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.
