The white reective bituminous waterproong membrane DERBIBRITE NT is a waterproong membrane composed of a copolymer bitumen with New Technologies which give it exceptional characteristics. DERBIBRITE NT is reinforced with a composite glass / polyester reinforcement impregnated with an acrylic coating with a high reection capacity. The functionality of the DERBIBRITE NT as a passive cooler allows energy savings and reduce production of CO2 during its roof life DERBIBRITE NT benets from a technology that makes it pH-neutral thus allowing the recycling of rainwater. When installing the DERBIBRITE NT a minimum slope has to be provided in accordance with the national rules and the requirements described in the specications. The membrane also has a border of 10 cm without coating to facilitate the application. Special characteristics SRI (Solar Reectance Index) Initial reectivity Initial emissivity Fungus resistance Fire resistance ASTM 1980 100 ASTM C-1549 81% (Criterium > 65 %) ASTM C-1371 & ASTM E-408 81% (Criterium > 80 %) ASTM Test method G 21 0 (no growth of fungi) Conform to EN 13501-5, classication BROOF (t1, t2, t3) according to ENV 1187 method. Fire resistance reports available upon request. Environmental characteristics pH-neutral Recycling Climatic change* Ecological Resistant Anti-tearing HALOGEN FREE Halogen free In accordance with ISO 14040 standard (Life Analysis Cycle) U1.3/01-080 (MFPA Leipzig) this waterproong membrane is 100% recyclable 3,4kg CO2/m² but its functionality allows it to comply with the criterion Factor 19 > Factor 4 Factor 4 : European objective that falls within the development of an European strategy for sustainable development in line with the kyoto protocol. It means that by 2050 the products will have to generate twice more value with 2 times less ressources Factor 19 : Due to its passive cooling effect DERBIBRITE NT saves 19 times more CO2 after installation than the produced total of CO2 during production.
