BRONCOÃÂ® CEMSHIELD APP membranes are factory fabricated waterproof sheets of predetermined thickness. These sheets are also known as APP ( Atactic Polypropylene) membranes, consisting of a specially formulated bituminous compound of distilled asphalt modified with selected high grade visco-elastic polymers (APP), stabilizers and inert fillers, reinforced with a robust, non-woven polyester reinforcement.
The top surface of the membranes is covered with thin layer of PF film, sand or mineral protection. The bottom surface is covered with Flam-O-Lene (Flammable PE Film). For exposed applications, the top surface is covered with a layer of natural slate flakes (mineral) to protect the membrane from UV rays and physical damage.
