Polyanchor® UDL 40 is an Atactic Polypropylene (APP) modified steep slope underlayment constructed with a fiberglass reinforcement. A specialized aggregate is embedded on the walking surface for skid resistance. Utilizing our patented ADESO® dual compound technology, the top layer is APP modified and the bottom surface is a proprietary SBS modified compound. This feature gives the membrane all the benefits of APP plus selfsealing properties around properly installed nails. The bottom surface is sanded to protect the self-sealing compound and to keep the roll in place for accurate alignment and preparation for nailing after roll-out.
