ELASTOSHIELD TS 4 and ELASTOSHIELD TS 4 MINERAL are high-performance prefabricated waterproof elastomeric membranes made from a modified distilled bitumen compound, a highly elastic thermoplastic elastomeric resin (SBS) and a heavyweight spunbond polyester nonwoven carrier, reinforced with glass strands parallel to the machine direction. This special carrier, in addition to having non-rotting qualities, gives the membranes excellent properties in terms of mechanical performance, ultimate elongation, high puncture resistance and dimensional stability. The special elastomeric compound provides excellent low temperature flexibility properties. The ELASTOSHIELD TS 4 and ELASTOSHIELD TS 4 MINERAL membranes are produced to the quality standards set by NAT^®   technology the innovative manufacturing system for the control of polymer matrix ageing in bituminous membranes.
