Elastoflex SA V Polar Base membrane is a self-adhered, elastomeric base ply low-slope roofing product designed for colder weather applications. It is manufactured using patented Adeso® dual-compound self-adhered technology, whereby a "true" Styrene-ButadieneStyrene (SBS) modified asphalt compound is applied on the top layer and an aggressive self-adhesive compound is applied on the bottom layer. Elastoflex SA V Polar Base membrane is built with a high performance reinforced fiberglass mat to ensure excellent dimensional stability. When used in conjunction with Elastoflex SA P Polar Cap or other approved SA cap sheet, Elastoflex SA V Polar Base provides cleaner application, improves application speed and removes the need for torches, hot asphalt or bonding adhesives on the job site. Elastoflex SA V Polar Base membrane is finished with polyolefin film with laylines on the top surface and a split release film on the bottom surface.
