Jun Ming ® Waterproof vapor permeable membrane is a new type of polymer waterproof material. In terms of production technology, the technical requirements for waterproof and breathable films are much higher than those of ordinary waterproof materials; At the same time, in terms of quality, waterproof breathable films also have functional characteristics that other waterproof materials do not have.
Jun Ming ® Steam barrier film, also known as insulation and moisture-proof film or moisture-proof vapor barrier film. The installation of vapor barrier film between the roof base and insulation layer can strengthen the building's air and water tightness, protect the thermal performance of insulation materials and maintain the structure, and reduce building energy consumption.
Product introduction
One、Waterproof vapor permeable film：It can enhance the air and water tightness of buildings, ensure that they are not affected by wind and rain, improve building durability, ensure building insulation performance, improve indoor air quality, and make the living environment more comfortable.
Parameters:
1.Water vapor transmission (g/㎡.24h,≥)：730。
2.2000mm, 2h impermeable
3.Maximum tensile force (longitudinal)(N/50mm，≥)：467。
4.Maximum tensile force (transverse)(N/50mm，≥)：190。
5.Nail rod tear performance (longitudinal)(N,≥)85。
6.Nail rod tear performance (transverse)(N,≥)108。
Two、Waterproof vapor barrier film：Jun Ming ® The vapor barrier is not breathable and can prevent indoor water vapor from penetrating into the enclosure structure, effectively ensuring the thermal performance and structural durability of the insulation material. Paired with Jun Ming ® waterproof and vapor permeable film, it can achieve excellent water vapor insulation effect.
