Product Data Sheet
FLEX 45 MIL TPO PLUS
(REINFORCE THERMOPLASTIC POLYOLEFIN MEMBRANE)
PRODUCT DESCRIPTION
The Flex 45 TPO Plus polyester reinforced thermoplastic polyolefin (TPO) roofing membranes are
designed for use in mechanically fastened and adhered roofing systems. The Flex 45 TPO Plus
membrane is manufactured in widths of 5’ and 10' for economical installations. Flex 45 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 45 TPO Plus membranes polyester reinforcement allows for structural movement with no splitting or
cracking. The Flex 45 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 45 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 45 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 45 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.
