FLEX SELF-ADHERING REINFORCED TPO MEMBRANE
GENERAL:
Flex Self Adhering TPO Membrane (SAM) is a heat-weldable, single-ply thermoplastic polyolefin (TPO)
sheet designed for fully adhered new roof construction and re-roofing applications. Flex (SAM) is
nominal 45 mil or 60 mil reinforced TPO membrane laminated to an elastomeric pressure-sensitive
adhesive. Flex (SAM) is based on advanced polymerization technology that combines the durability and
weatherability of ethylene-propylene (EP) rubber with the heat weldability of polypropylene. The
membrane is specifically formulated for long-term weather resistance without the use of either polymeric
or liquid plasticizers.
The pressure-sensitive adhesive is a 100% solid, hot melt adhesive that eliminates VOC and odor
concerns typically associated with fully adhered systems. The adhesive is factory applied to provide
uniform thickness yielding consistent field performance. An uncoated edge is maintained to allow for
heat welded field seams. The release liner is silicon coated on both sides to provide consistent, easy
release from the adhesive even if either side accidentally touches the adhesive again after removal.
Flex (SAM) is available in white (highly reflective) 45 mil and 60 mil nominal thicknesses. Available
widths are 5 and 10 ft in 50 and 100 ft rolls. The membrane is environmentally friendly and safe to install
with its VOC free pressure sensitive adhesive and heat welded seams.
Flex (SAM) white TPO membranes are LEED
TM
(Leadership in Energy and Environmental Design)
compliant. The U.S. Green Building Council (USGBC) designed by the LEED Green Building Rating
System. White Flex (SAM) is an E
NERGY S TAR ® and California Title 24 rated roof product.
