Building up principle of 3 layer breathable roof membrane:
3 layer breathable roof membrane, thermal laminated by high polymer material + polyolef in microporous membrane + high polymer material, we create this technology in China which is advanced all over the world. Polyolefin microporous membrane has excellent breathability, as well as good duration. Polyolefin microporous membrane has not only acid and alkali resistance, but also good extensibility which enable the fasresilience after tearing by nail so that to improve the sealing performance.
Characteristics of 3 layer breathable membrane:
A. Excellent Performance at water resistance B. Particular function of vapour permeability, so called breathable membrane
C. Good performance at UV resistance
D. Tear resistance, wear resistance, good extensibility.
E.Light and thin, antiskid, with good low temperature flexibility, suitable.
F.The 100% recyclable polymer materials, fit the ecologist requirements.
Waterproof and breathable membrane for building. This product uses different breathable formulations and production processes to produce products with different air permeability. The air permeability is widely used in the field of roofing waterproof from (50 to 25, 000 g / M 2 / 24 hours).
The waterproof and breathable membrane produced by Nantong Jinwei composite material Co., Ltd. uses the latest German and Italy technology to overcome the shortcomings of most of the previous manufacturers using glue or simple leaching. It is produced by non glue and non leaching process, so the surface is smooth, no wrinkling is bubbling, the compound fastness is good, and it is very high. Tensile strength and air permeability (up to 2000g/ square /24 hours), good waterproof performance (hydrostatic pressure testing more than 2 meters), anti aging (using BASF patent protection anti aging raw materials, 200 hours accelerated UV aging after aging more than 90%), high temperature resistance (temperature to 110 degrees). The waterproof breathable membrane of our company has been certified by the European Union CE, and passed the national building material testing center inspection, the quality is more guaranteed. At present, a very wide market in European countries is an integral part of the construction industry in these regions. At present, the main exports of Britain, Poland, Finland, Sweden, Norway, Italy, Spain, Greece, the Cyprus, Ukraine, Russia, Slovakia, Czech, Slovenia, Holland, Latvia, Southeast Asia, Australia, New Zealand, Canada, Chile, Argentina and other countries and regions.
Function of 3 layer breathable membrane:
Air-tightness of breathable membrane breathable membrane paves outside of the insulation system, wrap up the whole building, can strengthen air-tightness effectively and reduce air leak as well as convectional heat loss.
