ARDEX WPM 185 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 viscoelastic polymers and reinforced with a polyester reinforcement (Polyester and Fibreglass). ARDEX WPM 185 is coated with a slate mineral granule topping. 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 specific purposes.
Positive vapor barrier
Excellent resistance to atmospheric agents cold flexibility – 0°C
Resistant to chemical attack Withstand thermal shocks
