Elastoflex SA Polar Base membrane is a self-adhered, elastomeric base ply for low-slope roofing. This product is specially designed for colder weather applications. It is manufactured using patented ADESO® Dual-Compound Self-Adhered 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 Polar Base membrane is built with a high performance reinforced polyester mat to enhance puncture and tear resistance, and a proprietary “low-temp” self-adhered compound to enhance adhesion at lower temperatures.
When used in conjunction with Elastoflex SA P Polar Cap or other approved Polyglass cap sheets, Elastoflex SA 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 Polar Base membrane is finished with a polyolefin film displaying preprinted laylines on the top surface, and a split release film on the bottom surface.
