The breathable roof membrane is a synthetic underlay designed for warm pitched roofs, positioned directly above the insulation layer to manage moisture and prevent water ingress. This product is engineered to allow trapped moisture to escape while maintaining a waterproof barrier, reducing the risk of mold and structural damage. Its lightweight and flexible composition simplifies installation, making it suitable for both residential and commercial roofing projects.
Manufactured from polymer-based materials, the membrane typically features a non-woven or spun-bonded fabric core with a micro-porous coating to balance breathability and water resistance. Standard industry variants include UV-stabilized options for exposed applications, with typical weights ranging from 80 to 200 g/m² depending on the intended use. The material is often classified under EN 13859-1 for roofing underlays, ensuring compliance with European performance standards for water tightness, tensile strength, and durability.
Builders and contractors use this membrane in new construction and retrofitting projects to enhance roof longevity and thermal efficiency. The supplier, based in Haian Industrial Park, Jiangsu, offers export-ready materials with packaging tailored to bulk shipments. Buyers should confirm compatibility with their roofing system, as the membrane’s performance depends on correct installation above insulation and below the final roof covering.

Before ordering, verify the membrane’s compliance with local building codes and your roofing system’s specific needs. Check for certifications like CE marking or EN 13859-1, and request test reports for water tightness, breathability, and tensile strength. Confirm the supplier’s ability to provide consistent quality across large batches, as variations can impact performance.
Discuss logistics details such as Incoterms (e.g., FOB or CIF), packaging, and lead times. Bulk shipments typically require palletized rolls, so ensure the supplier can accommodate your volume and delivery schedule. For international orders, clarify port of loading and any export documentation required by Chinese customs.
Conduct quality checks upon receipt, including visual inspections for defects and measurements of roll dimensions. For critical projects, arrange third-party testing to validate the membrane’s Sd value, tensile strength, and UV stability. Request the supplier’s recommended installation guidelines to avoid common issues like improper seaming or inadequate ventilation.
