Product Data Sheet
FLEX FB 80 TPO PLUS DATA SHEET
(FLEECE BACKED, REINFORCED, THERMOPLASTIC POLYOLEFIN MEMBRANE)
PRODUCT DESCRIPTION
The Flex FB 80 TPO Plus polyester reinforced thermoplastic polyolefin (TPO) fleece backed roofing
membranes are designed for use in new or reroofing roofing systems. The Flex FB 80 TPO Plus membranes
are manufactured in widths of 5’ and 10’x 50’ for economical installations. Flex FB 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 FB
80 TPO Plus membranes polyester reinforcement allows for structural movement with no splitting or
cracking. The combination of the reinforcing scrim, fleece backing and the TPO membrane provide Flex FB
80 TPO Plus membrane with high breaking strength, tearing strength and puncture resistance. The specially
formulated membrane offers excellent resistance to solar UV and chemical exposure as well as remaining
flexible in cold temperatures.
USE
Flex FB 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 FB 80 TPO Plus membranes can be installed adhered directly
over layers of approved roof board insulation or cover boards. The Flex FB 80 TPO Plus membrane may
also be secured to the deck using an approved mechanically fastened system utilizing methods that have been
independently tested for wind uplift. The Flex FB 80 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.
