Waterproof And Breathable Membrane

In 2010, Xiong County Xiashi Packing Co., Ltd. successfully developed and launched the Jinbo® Waterproof and Breathable Membrane—a milestone that reinforced our position as a reliable manufacturer and trusted supplier in the global building materials industry.

Since then, our high-performance membranes have been widely exported to North America, Europe, and Southeast Asia, serving distributors, contractors, and construction companies seeking durable, sustainable solutions.

The Origin of Waterproof and Breathable Membrane

In the 1940s, European architects discovered that traditional waterproof materials, due to their airtight nature, trapped moisture in houses, easily leading to mold, rot, and bacterial growth. This seriously threatened the living environment. Based on this phenomenon, in the late 1980s, building experts developed waterproof and breathable membranes, which were widely promoted in Europe and America.

Buildings using waterproof breathable membranes are hailed as "breathing houses."

Product Working Principle and Characteristics

This waterproof and breathable membrane works by utilizing micropores for ventilation. Since the smallest water droplet diameter is 20 micrometers, while the diameter of a water vapor molecule is only about 0.0004 micrometers, the huge difference in diameter allows water vapor to diffuse through the micropores.

Due to surface tension, liquid water molecules cannot enter, thus achieving the function of waterproofing and breathability. Furthermore, it has withstood 168 hours of strong UV radiation and 80°C high-temperature testing. Our raw materials are 100% recyclable, so you don't need to worry about its adverse environmental impact. What you care about is also what we value highly!

Applications of Waterproof and Breathable Membrane

If you are building a house in the United States or Canada, your house will likely have a timber frame structure. Timber is strong, renewable, and beautiful, but it is not moisture-resistant. Moisture behind the siding or plaster can cause rot, warping, and even structural damage over time.

A waterproof and breathable membrane wraps around your house like a protective sleeve, preventing rainwater from seeping in while allowing moisture inside the frame to escape. Think of it as giving the walls the ability to breathe while preventing them from getting wet.

If you've been following green building trends, you've probably heard of the Passivhaus standard. These buildings are extremely airtight, making humidity control crucial. To improve energy efficiency, building experts often choose a waterproof breathable membrane to protect the building structure while achieving excellent airtightness. It's one of your most effective investments.
