House Dress Jinbo ®waterproof breathable membrane is a new type of waterproof breathable material made from spunbond polypropylene composite polymer. Its working principle is micro porous vapor permeation. The smallest diameter of a water droplet is about 20 microns, while a water vapor molecule is only about 0.0004 microns. This huge difference allows water vapor to discharge through micro holes via diffusion, while liquid water is blocked by surface tension.
Energy Efficiency: By strengthening air and water tightness, this membrane improves energy efficiency, effectively protecting the thermal performance of the building envelope. It avoids mold growth and ensures human settlement health by discharging vapor quickly.
Widely used in civil and commercial buildings, this "breathing" membrane is laid on the thermal insulation layer, protecting it effectively without the need for fine stone concrete, thereby reducing construction costs.
