DATA SHEET Product description SBS (styrene-butadiene-styrene) modified bitumen polymer waterproofing membrane. PARAFLEX Series prefabricated membranes include PARAFLEX NT (non-woven continuous filament polyester fabric reinforcing mat stabilized with mineral fibers, TERMOTENE thermoplastic film treatment on upper face, available thicknesses 3 and 4 mm); PARAFLEX W (glass tissue reinforcement, TERMOTENE thermoplastic film treatment on upper face, available thicknesses 3 and 4 mm); PARAFLEX ARD/HS (non-woven continuous filament polyester fabric reinforcing mat stabilized with mineral fibers, upper face surfaced with slate chippings, thickness 4 mm plus slate) and PARAFLEX ARD/S (continuous filament polyester fabric reinforcing mat stabilized with mineral fibers, upper face surfaced with slate chippings, density 4.5 kg/m2). Lower face of all types is coated with TERMOTENE film. On the optional PARAFLEX NT4 M version, both faces are coated with high value-added TEXTENE® preformed textured polymer fiber film, which enhances the product, improving durability and appearance. The bitumen-polymer compound’s special formulation ensures high mechanical performance, cold flexibility at temperatures down to -25°C), and excellent fatigue strength. In addition, the compound’s ultimate elongation exceeds 2000%. PARAFLEX Series membranes are supplied in strapped rolls, each accompanied by a Quality Control Certificate. PARAFLEX Series membranes comply with CE marking requirements where applicable. They contain no asbestos, tar or other dangerous substances. Certification European Technical Approval certification (formerly ICITE Agrement certification): PARAFLEX NT4 - PARAFLEX ARD/HS -PARAFLEX W3 - PARAFLEX ARD/S. Factory mutual approval: PARAFLEX NT - PARAFLEX ARD/S. Recommended uses PARAFLEX membranes are designed for waterproofing applications of all kinds. In particular, PARAFLEX membranes are ideal for use in cold climates or during cold weather. For membrane versions to be used in roofing, foundation and belowgrade applications, see the table below(1). For detailed documentation and guidance regarding product application, consult IMPER ITALIA srl Technical Services. (1) In compliance with applicable standards and AISPEC-SITEB-MBP guidelines.

(PARAFLEX SERIES continued) Methods of application PARAFLEX membranes are designed for easy torch application after priming, except for polyester-reinforced versions, which are secured using mechanical means. Waterproofing performance will depend to a significant extent on application methods. Special care must be taken at joins, which must be overlapped. Membrane must be laid to allow side laps of 8 to 10 cm and end laps of 12 to 15 cm. As bitumen-polymer compounds are damaged by exposure to UV radiation, PARAFLEX Series membranes should always be used under heavy-duty protection. If...
