Our breathable membrane is just used on the insulation layer of roof, like on the top of glass wool or other insulation material, and it is just under the roof tiles or plate. It is good moisture permeable (breathable), allows the moisture to pass through it and keep the drop water outside. It is also good waterproof and wind proof functional. Light weight and cheap price make it more welcome than traditional bitumen roof felt.

This 3 layer breathable membrane(thermal laminated by non woven PP + waterproof and vapour permeable membrane + non woven PP).
"KangDa" breathable membrane paving on the top of the insulation system, it can strengthen the water tightness of the building, as well as to eliminate humidity inside the containment by the unique breathability, thus to retain the duration of building effectively, playing a part in thermal insulation, energy conservation and living environmental improvement.

2. Specification
Weight(gsm): 90, 100, 115, 120, 135, 140, 160 and so on.
Width: 1.5M,1m
Length: 50M or jumbo roll

3. Products characteristics and function
"KangDa" breathable membrane has excellent performance at water resistance, high vapour permeability, Good performance at UV resistance and 100% recyclable polymer materials, fit the ecologist requirements.

Water tightness of "KangDa" breathable membrane: Thanks to the prominent waterproof performance, "KangDa" breathable membrane can wrap building tightly, protect the building from corrosion of water vapour and rain, guarantee good insulation performance and well durability of building enable the building to be more energy conservation and environmental protection.

Permeability of "KangDa" breathable membrane: "KangDa" breathable membrane paves outside of the insulation system, enable the water vapour inside the insulation system to exhaust, solve the condensation problem, protect the insulation system.

Reduce construction cost: "KangDa" breathable membrane can protect the insulation system, saving the fine concrete or the film waterproofing materials which regularly paved on top of insulation system so that to reduce the construction cost.

4. Application
Mainly used as underlay for pitched roof and enclosure protection for insulating layer of walls

5. Quality control
We pay high attention to the quality of products, advanced production equipments, perfect detection means, powerful ability on technical research and management formed the preeminent "KangDa" quality.

6. R&D
"KANGDA" breathable membrane thermal laminating from 100% returnable polymer material by the advanced technology, we own independent intellectual property which enable us to be the only company in China who scale produce membrane by this technology.
