ARDEX WPM 160 is an A.P.P. (Atactic Polypropylene) plastomeric type modified bitumen membrane, consisting of a specially formulated bituminous compound of distilled asphalt modified with selected high-grade visco-elastic polymers and reinforced with a polyester reinforcement. ARDEX WPM 160 is coated with either a sanded or talc top surface finish, while the bottom surface is embossed and protected by a heat-sensitive polythene film This type of finish for the lower surface has been chosen for two specifc purposes.
1. To act as a temperature gauge during When the film melts it shows that the compound is at the correct temperature.
2. The embossing is to allow the gases to rapidly escape when heated to its correct installation temperature avoiding possible problems of bubbling and
