Breathable membrane by hot rolling coating

Our product are waterproof and breathable or heat insulation widely used in construction for roofing felt and underlay.

Our roofing membrane is a three layer highly breathable, fully waterproof membrane, constructed from high tensile spun-bonded polypropylene layers, around a microporous PE film. The outer layer forms the functional waterproof surface; the middle layer is the breathable waterproof membrane and the inner layer protects the membrane from abrasion and damage, also giving additional strength.

Products characteristic

Excellent performance at water reisitanceParticular funtion of vapour permeability, so called breathable membraneGood performance at UV resistanceTear resistance, wear resistance, good extensibilityThe 100% returnable polymer materials, fit the ecologist requirements.

Functions of products

Improve watertightness of building, prevent the construction from the invastion of wind and rain, protecting the structural masterials and equipmnets inside roof and wall.Improve the energy saving and insulation effect. Due to the unique water proof and vapour permeable performance, when forming the protection to the insulating layer, it can also effectively avoid the negative influence from the temperature difference between interior and exterior. Hence, it increasing the effects of insulation and energy saving as well as providing the continuously energy saving.Shorten the construction period. Thanks to the good water resistant performance, interior construction and exterior can be performed at the same time so that shorten the construction period, reduce the construction cost.Improve the residential environment. Because of the special breathable function, the interior vapour can natural exhaust, will effectively avoid mould and condensation, keep dry, permeate and comfortable indoor, improve the residential environment.
