HouseDress Jinbo® waterproof breathable membrane have unique functionality and stronger physical properties than traditional waterproof material. Because of its unique functions of waterproof, vapor permeation and windproof, it can strengthen the air tightness and the water tightness of buildings. Its unique vapor permeability can make the water vapor in the structure discharged quickly and avoid the breed of mold, which can effectively improve the energy efficiency of building envelope, make building envelope maintain the best use of the state for a long time and perfectly solute the problem of damp and human settlement health. The water vapor is discharged quickly so that the thermal performance of envelope structure is protected. It is a kind of new energy-saving materials, healthy and environmentally friendly.
House Dress Jinbo® waterproof breathable membrane has good performances in waterproof, vapor permeation, windproof and aging resistance, widely used in the field of architecture. The waterproof breathable membrane can strengthen the water tightness of buildings and meanwhile discharge the steam in enclosure with its unique steam permeability function. Therefore, it can effectively extend the service life of buildings and has the function of heat preservation, energy saving and improving the living environment. Its unique function of breath has became a great invention and innovation in China building application field. Meanwhile, because of its functions of waterproof, anti-mite, anti-mildew, antibacterial, ventilation and isolation and so on, it is widely used in the fields of modern industry, agriculture, home textile, clothing, medical and health and packaging. House Dress Jinbo® waterproof breathable membrane is a necessary new material for protection and isolation.
House Dress Jinbo® waterproof breathable membrane is a new type of waterproof breathable material made from spunbond polypropylene composite polymer. In terms of production process, its technical requirements are stricter than ordinary waterproof material’s. Meanwhile, in terms of quality, it has unique functions that other waterproof material does not have. Its working principle is micro porous vapor permeation. The smallest diameter of the droplet is about 20 microns, but the water vapor molecule is only about 0.0004 microns in diameter. So there is a huge difference in the diameter of them. The water vapor can be discharged through the micro holes on the basis of diffusion principle. Liquid water or water drop have surface tension so that water molecules can not be discharged. Therefore, House Dress Jinbo® waterproof breathable membrane can proof water and permeate vapor.
Advantages and functions of House Dress Jinbo® waterproof breathable membrane
1. Function introduction of House Dress Jinbo® waterproof breathable membrane
House Dress Jinbo® waterproof breathable membrane is laid on the surface of building insulation layer just like a layer of protective clothing. It can strengthen the air tightness and the water tightness of buildings. Meanwhile its unique vapor permeability can make the water vapor in the structure discharged quickly , so as to save energy, improve building durability and ensure the indoor air quality. Also, it can make a more effective guarantee for the drying of building envelopes (external wall and roof) and a more significant thermal insulation efficiency, effectively prolong the service life of buildings and make buildings more comfortable and energy saving.
High air tightness:
1. House Dress Jinbo® waterproof breathable membrane is laid on the surface of building insulation layer and cover the whole building. Its unique non confined pore, great wind resistance performance and effective anti-aging can substantially improve the air tightness of buildings, so as to reduce the air leakage and heat loss and protect the insulation layer.
2. High water tightness
House Dress Jinbo® waterproof breathable membrane has great water resistance to protect buildings from water vapor and rain. It can improve the durability of building structure and effectively ensure the thermal insulation effect and service life of the building, so as to make the building more energy saving and environmental protection and protect property value.
National Construction Engineering Quality Supervision and Inspection Center carried out thermal test for waterproof breathable membrane with a net hanging plaster external insulation system. Test results showed that the value of thermal resistance of waterproof breathable membrane can reach to 0.307 with 3cm air layer. Its is equal to two times of the value of thermal resistance of the air with the same thickness and 43% of EPS insulation board in accordance with the regulations in Code for Thermal Design of Civil Buildings GB50176. Therefore, Its heat preservation effect is remarkable.
3. Persistent vapor permeability
House Dress Jinbo® waterproof breathable membrane is laid on the outside of the insulation layer with an air permeability above 1000g/m•day. It can quickly and effectively discharge the water vapor in the structure, so as to reach the natural dry, protect thermal performance of building envelope and guarantee the durability and service life of the material. Meanwhile it can solve the problem of damp and dew. Its great bio-control function can protect the roof from the mold breeding, improve the air quality of the room, protect insulation layer and make the living environment more comfortable.
A large number of surveys show that when the temperature is different between hot and cold, condensation phenomenon will occur. At that time, drops of water will form in the roof or wall surface, attack a building or a heat insulating layer, reduce the thermal efficiency of the thermal insulation layer and make a direct impact on the durability of the building. After laying House Dress Jinbo ® waterproof breathable membrane, the water vapor can be discharged through the membrane, making waterproof more secure.
4. Reduction of the engineering cost
House Dress Jinbo® waterproof breathable membrane can protect thermal insulation layer overall, directly and effectively. Therefore, other protective layer and steam exhaust measures do not need laying on the outside of thermal insulation layer. What’s more, fine stone concrete or film waterproof material is not deeded, too. It can greatly reduce the cost of the project.
2. 7 unique advantages of House Dress Jinbo® waterproof breathable membrane
1. High temperature resistance — when operating temperature reaching to 80℃, it is still stable.
2。 Low temperature resistance — it has great toughness. Even if the temperature drops to -40℃, it can maintain elongation at 5%.
3. Corrosion resistance — it shows inertia, acid and alkali resistance, water resistance and various organic solvents resistance for most chemicals and solvents.
4.Biological — antibacterial, anti-mildew, anti-mite, and resistance to insect invasion.
5. Durability — it experiences the test of 168 hours of strong UV exposure and high temperature of 80℃.
6.Flame retardant — flame retardant performance can reach the national standard B2 level.
7. Recoverable — it adopts 100% recyclable materials and meet the requirements of green environmental protection.
