POLYVAP RADONSHIELD P-AL is a prefabricated ELASTOMERIC-PLASTOMERIC (Plastomer-Polymer Bitumen) waterproofing vapour control membrane offering excellent performance. Made from a special distilled bitumen compound modified with a high percentage of special polymers such as POLYPROPYLENE (APP) and POLYOLEFIN (APAO), with the addition of special anti-ageing additives that provide blends with superior performance characteristics. POLYVAP RADONSHIELD P-AL is a membrane produced to the standards set by NAT® technology, the innovative production system for the control of polymer matrix ageing in bitumen membranes. POLYVAP RADONSHIELD P-AL has a stabilized polyester nonwoven COMPOSITE carrier laminated with aluminium foil that gives tensile strength in all directions, as well as good dimensional stability and excellent water vapour transmission resistance properties.
