Iking Waterproof Breathable House Wrap for Building Envelope

A waterproof breathable membrane is a multi-layer, high-performance material typically consisting of a waterproof layer, breathable layer, and a protective layer. It effectively blocks the penetration of moisture and pollutants while allowing water vapor to pass through, ensuring excellent breathability. It is widely used in the construction industry.

A waterproof breathable membrane has a microporous structure. When water vapor molecules encounter the membrane they are able to penetrate through it through capillary action. When moisture is converted into liquid droplets, surface tension prevents them from penetrating the membrane, thus preventing water from penetrating.

A waterproof breathable membrane typically has a service life of over 10 years, depending on the operating environment, exposure conditions, and product quality. Under normal conditions, it effectively resists UV rays, moisture, and temperature fluctuations, extending its service life.

Depending on the product specifications, a waterproof breathable membrane can typically withstand hydrostatic pressures exceeding 1.5 meters (thin films) to over 2 meters (thick films), allowing it to withstand high water pressure without breaking.

We use high-quality raw materials and utilize rigorous production processes, such as hot-press lamination, to ensure membrane quality. Each batch undergoes rigorous testing for temperature resistance, breathability, and hydrostatic pressure to ensure it meets standards.
