Performance With A Higher Purpose

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.

What is Breathable Membrane?

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.

What specifications of products can we provide?

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.

Applications of Breathable Membrane

1. Building Exterior Walls

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.

2. Roofing Systems

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.

3. Specialized Buildings and More Applications

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.

Working Principle

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.

Storage Precautions

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.

Actual application data shows that project waterproofing qualification rates can consistently reach 99.9%.

The application cases in building roof and exterior wall waterproofing offer strong reference value.

Cases

In 2024, a high-end residential complex construction project in Hebei selected Jinbo Vapor Barrier to cover 150,000 square meters of roof and exterior wall systems, with Xiong County Xiashi Packing Co., Ltd. providing full technical support.

After the vapor barrier effectively blocked rainwater and vapor penetration, indoor building humidity was controlled within the 55%-65% range, mold occurrence dropped by 45%, and building structure lifespan was notably extended.

Following project implementation, the client recovered procurement costs within 8 months, demonstrating product's strong return on investment in modern construction. This practical cases in building basement and foundation engineering are equally noteworthy.

How to install Vapor Barrier in compliance with standards?

Xiashi Packing offers professional installation guidance videos and on-site technical services, requiring overlap widths of no less than 15cm and the use of matching specialized sealing materials.

Are you looking for a manufacturer that supplies window tape? Consider Xiashi Packing from China—and our brand, Jinbo. With over 40 years of industry experience, we utilize high-quality materials and refined production processes to deliver products that can be fully customized to meet your specific requirements.

What’s window tape?

House Dress Jinbo Window Tape is a “professional butyl sealing tape” for building sealing, waterproofing and energy saving. It is mainly used for sealing window openings, internal corners, pipe joints and membrane laps. It is a necessary auxiliary material for passive houses, prefabricated buildings and exterior wall insulation systems.

With strong self-adhesive, waterproof, weather-resistant and anti-aging properties, it can work with a waterproof breathable membrane, vapor barrier membrane, and reflective insulation membrane. It effectively blocks rainwater and moisture, prevents mold and condensation, improves building airtightness and energy efficiency, making it the first choice for global construction buyers and wholesalers.

Our window tape is different from ordinary tape

It uses butyl rubber, has excellent weather resistance, high waterproofing and breathability.

It is specially designed for window opening sealing, matching building envelope systems.

It is more durable, stable and professional for passive houses, prefabricated buildings and exterior wall insulation projects.

Product specification

The House Dress window adhesive tape has excellent weather resistance. It does not run at a temperature of 80℃ and maintains good toughness at -40℃. Combined with 168-hour heat air aging and strong UV aging tests, it does not deteriorate or deform under outdoor long-term use, meeting the engineering usage requirements in different climate zones around the world. This window adhesive tape adopts a pressure-sensitive self-adhesive design. It is easy to peel off for construction, and does not require additional application of interface agents to achieve a firm bond. This significantly improves the on-site installation efficiency. At the same time, it can achieve self-sealing at nail holes, effectively preventing rainwater and moisture from seeping into the interior of the wall through the nail holes, protecting the insulation layer and structural layer from becoming damp and unstable.

Why do we need window tape?

1. Stop water leakage completely

Window gaps are the easiest place for rain and moisture to enter. Without window tape, walls will get wet, moldy and damaged. Professional window tape seals all gaps tightly and keeps water out forever.

2. Save energy and reduce costs

Unsealed windows cause huge heat loss. Window tape improves airtightness, keeps warm in winter and cool in summer. It helps you save a lot on air conditioning and heating bills.

3. Avoid mold and structural damage

Moisture inside the wall will destroy insulation layers and shorten building life. Window tape works with waterproof breathable membrane and vapor barrier membrane to keep walls dry and safe.

4. Long-lasting, no aging, no maintenance

Ordinary tape cracks and peels off quickly. Our House Dress window tape is made for outdoor use, anti-UV, high and low temperature resistant, stable for many years.

In short: Window tape is not a small accessory—it is the most important protection for your windows, walls and whole building.

Do you know the correct way to use window tape?

First, clean and keep the window opening surface dry and free of dust.

Then handle corners with 1–1.5 times the joint width for tight sealing.

Maintain a lap overlap of at least 10 cm between tapes; press firmly with a roller to ensure full adhesion without bubbles.

Finally, seal all four sides of the window and work with waterproof breathable membrane to achieve the best waterproof, airtight, and long-lasting performance.
