Polyglass® has introduced Elastoflex SA Base membrane, a self-adhered, elastomeric base ply low-slope roofing product manufactured using patented ADESO® dual-compound self-adhered technology, whereby a true 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 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.

When used in conjunction with Elastoflex SA P or other approved Polyglass self-adhered cap sheet, Elastoflex SA Base provides cleaner application; improved application speed, and removes the need for torches, hot asphalt, or bonding adhesives on the jobsite. Elastoflex SA Base membrane is finished with film that has laylines on the top surface and a split release film on the bottom surface.
