Elastomeric-plastomeric polymer distilled bitumen waterproofing membrane. PLANA PREMIUM P is a prefabricated ELASTOMERIC-PLASTOMERIC (Plastomer-Polymer Bitumen) waterproofing membrane offering good performance. Made from a special compound with a high percentage of polymer, formulated with distilled bitumen modified with special polymers that give the membrane excellent elastic, plastic and rubber-like properties. PLANA PREMIUM P is BROOF(t1) certified to the requirements of the external fire performance standard EN 13501-5. PLANA PREMIUM P has a spunbond polyester nonwoven carrier stabilized with glass strands parallel to the machine direction. The carrier gives good tensile strength (in all directions) and puncture resistance, with excellent dimensional stability. PLANA PREMIUM P assures good dielectric and resistive properties (Volume Resistivity 5,50·10+14 Ωcm); it can be used to isolate structures from possible forms of “stray currents” in the ground near electric rail and tram lines. The special type of compound ensures remarkable characteristics of low temperature flexibility and due to its waterproof properties this membrane does not absorb humidity and its electrical resistance remains unaltered in time.
