Elastoflex S6 25 is a smooth surface Styrene-Butadiene-Styrene (SBS) modified bitumen roofing membrane reinforced with a polyester mat saturated with a rubberized asphaltic compound. The non-woven reinforcement provides superior tear strength and puncture resistance.
Elastoflex S6 25 is designed for use as a base ply or interply layer in multi-layer low-slope assemblies, and is available in a film or sand top surface and a film or sand bottom surface.
Application methods include hot asphalt or cold adhesive when the membrane is sand backed. When a top surface film configuration is selected, successive system layers can be heat welded with an additional ply of Elastoflex S6 25, Elastoflex S6 G or other Polyglass SBS cap sheet. A top film configuration also allows for the application of a variety of Polyglass SBS or APP self-adhered cap sheets.
