Elastoflex SA Base Plus membrane is a self-adhered, elastomeric base membrane, manufactured using patented ADESO® dual-compound self-adhesive technology, whereby a “true” Styrene-Butadiene-Styrene (SBS) modified asphalt compound is applied on the top layer and an aggressive self-adhesive compound is applied on the bottom layer. Elastoflex SA Base Plus membrane is built with a strong non-woven polyester mat to enhance tear strength and puncture resistance, providing a robust membrane that resists natural forces and other factors on the rooftop. Elastoflex SA Base Plus membrane is finished with polyolefin film having laylines on the top surface and a split release film on the bottom surface.
Elastoflex SA Base Plus can be used as a base sheet in “Stick 1–Torch 1” applications where the cap sheet is heat welded. Polyglass offers a variety of compatible torch cap sheets, such as Elastoflex S6 G and Elastoflex S6 G HP, and self-adhered options such as Elastoflex SA P.
