Covers for: Technical properties Tensile strength Tear strength Folding resistance The 2-tone characteristic also limits light transmission and significant reduces growth of harmful "microorganisms". Merging into the landscape... Flame retardancy Rating FR ZE Antistatic measurement in ATEX zone - AS Management systems Sustainable, innovative membranes Composed of a PVC-coated polyester complex and a PVC coating, the polyester reinforcement ensures very high structural strength and optimum flexibility: • good bending and perfect dome adaptation; • easy to make up and install on site; • control of gradual gas expansion. This coating has been specially designed to ensure optimum imperviousness and resistance to chemical and organic effluents. Stam 4739OR and ZE bio-energy membranes are an ideal solution to this problem! Extensive architectural potential 100% recyclable Serge Ferrari believes that eco-design involves considering its membranes' impact on the environment throughout their life cycle: from development stage to manufacturing, transport and installation, right through to their end-of-life management. The unique TEXYLOOP process ensures that Serge Ferrari membranes remain an infinite resource and are no longer a burden for the environment. Adhesion (conventional finish) 12 / 12 daN/ 5 cm Thanks to their green/grey 2-colour coating, Stam 3739, 4739, 5739, 6739 bio-energy membranes merge perfectly into an urban or rural landscape.
