Vapor Barrier Membrane

The Jinbo Vapor Barrier Membrane produced by Xiong County Xiashi Packing Co., Ltd. is powerful to block indoor moisture and seal the insulation layer. It is weather-resistant and durable, and easy to build.

With the breathable membrane, it is highly efficient, energy-saving, moisture-proof and mold-proof, which can form a complete waterproof air-proof system.

What is Vapor Barrier Membrane? 

The Vapor Barrier Membrane is a kind of high-blocking, high-waterproof and low-permeability architectural functional film. It is mainly laid on the inside of the building insulation layer. By blocking the indoor water vapor from penetrating into the wall, roof and insulation layer, it can avoid condensation, mold and moisture inside the structure from the source.

It effectively protects the performance of insulation materials, improves the airtightness and watertightness of the building, reduces energy consumption and prolongs the service life of the structure. It is often used with the outer waterproof and breathable membrane to form an architectural respiratory protection system of "internal vapor isolation and external ventilation".

Product specification

Our advantages

Jinbo Vapor Barrier Membrane is developed and produced by a professional enterprise that inherits three generations and cultivates environmental protection building materials. It has excellent vapor insulation performance and strong watertightness. It can efficiently block the indoor moisture from entering the insulation layer and avoid condensation, mold and insulation failure from the root cause.

The product is resistant to high and low temperature, anti-aging, corrosion-resistant, flame retardant, meets the standard of stable and durable physical properties, and adapts to a variety of architectural scenarios. With the same series of waterproof and breathable membranes and supporting auxiliary materials, it forms a complete sealing system.

The construction is more convenient, greatly reduces the engineering cost, and significantly improves the airtightness, energy-saving effect and structural life of the building. It has been successfully applied to major projects such as BASF and Starbucks, with reliable quality and excellent market reputation.

Notes

• Lay on the inside of the insulation layer, flat, without wrinkles and damage.

• The connection width is not less than 10cm, and the connection is tightly sealed.

• The connection, doors and windows, and the perimeter of the pipe are sealed with matching tape.

• Install it firmly with a special fixing part, and seal the nail hole.

• Avoid rain, snow and wind in construction, prevent scratches and damage, and repair damage in time.

• It is matched with the outer waterproof and breathable membrane to form a complete protection system.

FAQs

Q: Should the air diaphragm be laid indoors or outdoors?

A: The air diaphragm is laid on the inner side of the insulation layer (indoor side), and it is matched with the outer waterproof and breathable membrane to form a building protection system of "internal air insulation and external ventilation".

Q: What is the difference between air diaphragm and waterproof breathable membrane?

A: The air barrier membrane blocks steam and prevents moisture from entering the insulation layer; the waterproof breathable membrane is waterproof and breathable, which discharges the moisture in the structure and blocks rain. The combination of the two has the best effect.

Q: Can the broken diaphragm still be used?

A: Small damage can be repaired with matching butyl tape; large-area damage is recommended to be replaced, otherwise it will affect the effect of vapor isolation, sealing and insulation.
