UV Resistant Breather Membrane

House‑wrap UV resistant breather Membrane made in China work on a microporous physical mechanism to deliver waterproofing alongside vapor permeability. Rain droplets as large as 20 μm cannot pass through the membrane, yet 0.0004 μm water‑vapor molecules escape outward. This solves common building issues including interior condensation, mold growth and insulation failure caused by trapped moisture.

Core operating principle and product performance advantages

This UV resistant breather Membrane house wrap adopts an S‑pattern embossing production technique to boost material toughness, resilience, abrasion performance and onsite construction‑damage resistance. It comes with seven major physical benefits. It keeps stable performance under high temperatures up to 80 °C and still maintains 5 % elongation at‑40 °C. The material withstands acid‑alkali corrosion and delivers antibacterial, anti‑mold and insect‑resistant performance. It has completed 168‑hour UV plus high‑temperature aging testing and satisfies national Class B2 flame‑retardant requirements. All raw materials can be recycled, complying with green building environmental requirements.

Test data from NIST shows correct installation of this breather membrane may cut building heating and cooling energy use by as much as 40 %. Used together with a 3 cm air gap, thermal resistance hits 0.307, double the value of a standard air layer. It helps insulation stay dry long‑term and prevents thermal‑performance degradation.

The UV resistant breather Membrane reaches 1500 mm water‑column waterproof performance within two hours. No cracking occurs with bending at‑30 °C. Tensile strength remains at or above 80 % after thermal aging. When fitted inside building assemblies away from direct sunlight, the product delivers 10‑15 years of reliable service life. The exposed membrane withstands UV rays for four months. Do not leave it under continuous direct sunlight during installation.

Building Application Scope and Installation

House Dress Jinbo® UV resistant breather membrane should be installed on the exterior cold side of the insulation layer; it is compatible with a variety of building structures, including steel plate composite wall systems, plastered curtain wall systems, externally mounted stone cladding systems, pitched-roof systems, and vertically jointed metal roofing systems.

This breather membrane is suitable for buildings such as light-gauge steel and wood-framed residential homes, civilian villas, steel-framed industrial plants, commercial complexes, sports centers, food processing facilities, and passive energy-efficient buildings. Domestic implementation projects include the BASF factory, the Starbucks Industrial Park, and the Danzhou Sports Center; the product is exported year-round to international markets including Europe, the Americas, and Estonia.

Key construction considerations: Lay the UV resistant breather membrane in the direction of water flow; the overlap width shall be no less than 10 cm; for door and window openings, the overlap width should be 1 to 1.5 times the width of the main frame joint. All overlap joints and opening nodes must be sealed using House Dress Jinbo's original factory-made overlap tape and flexible flashing tape. For rough surfaces, it is recommended to apply an interface primer to enhance the adhesion strength of the tape. For the indoor warm side of the insulation layer, a vapor barrier membrane should be installed to form a complete moisture vapor control system. During installation, use appropriate tools such as insulation nails, nail guns, and compacting scrapers. Storage conditions: Store in a cool, dry indoor environment; the unopened product has a shelf life of 12 months.
