Xiashi Packing is a reliable manufacturer and supplier, and Breathable Membranes constitute a major product category we offer. As a direct-sales factory, we provide one-stop services—including customization tailored to the specific requirements of your project—along with relevant technical support.
When you choose Jinbo® Breathable Membrane, you’re choosing a trusted supplier that professionals count on. Our membrane features a robust three-layer "sandwich" structure: durable PP spunbond non-woven fabric on both the top and bottom, with a high-performance PE (polyethylene) core. This is the material known in the construction industry as "breathable paper"—a reliable choice for keeping buildings dry and comfortable.
At Xiong County Xiashi Packing Co., Ltd., our Breathable Membrane ranges in weight from 90g to 200g, and in size from 75mm to 3.2m, customized to your specific working conditions. If these specifications do not meet your needs, please let us know, and we are happy to provide customized solutions to meet your specific project requirements. We can also select the appropriate durability level based on specific application needs—whether it's lightweight residential protective material or a more durable commercial solution.
Breathable Membrane is widely used in the exterior walls of timber, steel, and concrete buildings. It is laid on the outside of the insulation layer and the inside of the finishing layer, preventing rainwater and wind-driven rain from penetrating the wall while allowing moisture inside the wall to escape effectively, preventing wood rot, steel corrosion, and condensation, thus extending the building's lifespan.


In pitched roofs, metal roofs, and similar applications, breathable membranes are laid as an underlayment between the roof slabs and tiles. They prevent rainwater infiltration while allowing moisture to escape from the attic or roof, preventing condensation buildup and insulation dampness, keeping the roofing system dry and efficient.
Passive houses and prefabricated buildings also extensively use breathable membranes as a key material for airtight building envelopes. Furthermore, they are suitable for sealing door and window openings, renovating old houses, and cold chain buildings. In short, Jinbo® breathable membranes are the ideal choice for spaces that require both rain protection and ventilation.
The working principle of House Dress Jinbo® Breathable Membrane is microporous 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 microholes on the basis of the diffusion principle. Liquid water or water drops have surface tension so that water molecules cannot be discharged.
Therefore, House Dress Jinbo® Breathable Membrane can be waterproof and permeate vapor.

When you receive our Breathable Membrane, here's a helpful tip: please store them in a cool, dry place away from direct sunlight. Keep them intact on a pallet or on a clean, flat surface. This helps maintain the adhesive's effectiveness and prevents premature film aging.
