Multi-purpose PVC Tarpaulin Sheet
“Multi-fiber PVC Single-ply roof waterproofing roll goods” products have been developed on the basis of Multi-fiber & enhanced PVC waterproofing membrane.Ltd. Its research standards adopt the standards of ASTM D4434-2006 of U.S. This waterproofing system is applicable to a variety of roof structure, which has light weight, waterproofing, airtight insulation, faster construction, easy maintenance, rich aesthetic color, windproof and tearproof ,environmental protection, especially the significant reduction in cost advantages of integrated roof construction.the construction materials and components have been confirmed by the Shanghai Quality Supervision, Inspection and Testing Station determination.
There are two types of this product. Type I follows the Quality Standard DIN 16734-86. Type II is higher than the Quality Standard DIN 16734-86. Please see detail below.
