Specifications
PE film coated with Nonwoven ( non-breathable or low vapor permeable or high vapor permeable, 2layers or 3layers)Roofing membrane/ breathable membrane: laminated by one layer of modified microporous PE film and two layers of reinforced non woven.
Excellent performance at water resistance.
- 1. Products characteristic
Excellent performance at water reisitance
Particular funtion of vapour permeability, so called breathable membrane
Good performance at UV resistance
Tear resistance, wear resistance, good extensibility
Light and thin antiskid, with good low temperature flexibility, suitable for construction in different condition.
The 100% returnable polymer materials, fit the ecologist requirements.
- 2. Functions of products
A. Improve watertightness of building, prevent the construction from the invastion of wind and rain, protecting the structural materials and equipmnets inside roof and wall.
B. 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.
C. 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.
D. 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,
- 3. Application of products
Mainly used as underla for pitched roof and enclosure protection for insulating layer of wails.
- Roofing application.
- Wall application.
Use: Breathable roofing underlay positioned immediately above the insulation layer in a warm pitched roof, or in a cold pitched roof (ventilayed or unventilated). Breathable roofing underlay for use under tiles and sheeted roofs, over open rafters or on to fully boarded substrates. Breather membrane for timber frame wall construction.
