Product Description

 

 

 

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.
The working principle of House Dress Jinbo ® waterproof breathable membrane 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.
