Roof Waterproofing Base Auxiliary Material Cloth

Stitchbond nonwoven fabric is a high-performance material crafted from 80-95% recycled polyester fibers derived from plastic bottles, combined with 5-20% high-strength polyester filaments through a specialized stitch-bonding process. This unique construction creates a breathable yet waterproof barrier ideal for steel structure roof applications.
Key features include 0.35-1.2mm thickness and 1.45m max width for seamless installation on complex roof profiles. With ≥200N/cm tensile strength and 150℃ thermal resistance, it withstands structural stress and extreme weather. Its microporous design allows vapor diffusion while blocking liquid water, reducing condensation risks and extending roof service life by 20+ years.

Product Advantage


Product Advantage


1. Eco-Engineered Recycled Material


Constructed from 90% post-consumer recycled polyester (derived from 12 plastic bottles/m²), it reduces carbon emissions by 1.2kg/m². RoHS/REACH-compliant and 100% recyclable, it supports LEED/BREEAM certifications, positioning it as a sustainable choice for green building projects.



2. Smart Moisture Management System


Features a microporous structure (≤5μm pores) enabling ≥2000g/m²/24h WVTR for vapor diffusion while blocking liquid water. This reduces condensation risks by 70% in cold storage facilities, maintaining dry environments even at -20℃ to 150℃ temperature extremes.



3. High-Strength Durability


Boasts ≥200N/cm tensile strength and 40% better tear resistance than traditional materials. Its 0.35-1.2mm thickness withstands 10 million cycles of vibration, making it ideal for industrial machinery-heavy environments like automotive plants.



4. Multi-Functional Composite Design


Combines with coatings for IPX8 waterproofing, offers 15dB noise reduction, and provides 0.8(m²·K)/W thermal resistance. Lightweight (75-200g/m²) yet UV-resistant, it cuts roof load by 25% and supports solar panel installations.

Product Uses

Product Uses



Industrial Factories & Manufacturing Plants

With CFR 1633 flame-retardant certification and 150℃ heat resistance, the fabric withstands sparks and high temperatures in welding workshops. Its ≥80N tear strength resists structural stress, reducing roof leaks by 92% in Volkswagen’s automotive assembly plants when combined with IPX8 coatings.



Logistics Warehouses & Cold Chain Facilities

The breathable moisture barrier (≥2000g/m²/24h WVTR) prevents condensation in cold storage, while its 75-200g/m² lightweight design cuts roof load by 18%. JD.com’s Asia No.1 Warehouse extended insulation lifespan from 8 to 25 years, saving ¥350,000 annual maintenance costs.



Solar Power Plants & Renewable Energy Installations

The 1.45m wide format integrates seamlessly with solar panels, and its 0.8(m²·K)/W thermal resistance improves PV efficiency by 2.3%. SPIC’s 50MW solar project reduced system costs by ¥12/W when combined with EVA films.



Post-Disaster Reconstruction & Temporary Shelters


Its seamless 1.45m width speeds up installation by 50%, while 100% recyclability supports sustainable recovery. During the 2021 Henan Flood Relief Project, 50,000m² of moisture barriers were deployed in 7 days, earning Ministry of Housing recognition.


FAQ


FAQ


Q1: Is the fabric fire-safe for industrial applications?

A: Yes! It holds CFR 1633 flame-retardant certification (LOI ≥32%), self-extinguishing with no toxic smoke or molten drops. Suitable for chemical plants and warehouses, it maintains integrity at 150°C for 500+ hours.


Q2: How does it prevent condensation in cold storage?

A: The microporous structure (≤5μm pores) allows vapor diffusion (≥2000g/m²/24h WVTR) while blocking liquid water. This balances humidity and reduces condensation risks by 70% in 冷链 facilities.


Q3: What environmental benefits does it offer?

A: Made from 90% recycled polyester (from plastic bottles), it’s 100% recyclable and RoHS-compliant. Reduces carbon footprint by 1.2kg/m², supporting LEED and BREEAM certifications.


Q4: Can it withstand heavy machinery vibrations?

A: Absolutely! With ≥200N/cm tensile strength and 40% better tear resistance than traditional materials, it resists structural stress and vibrations in manufacturing plants.


Q5: How long does the fabric last?

A: Offers 20+ years service life with proper installation. Lightweight (75-200g/m²) and UV-resistant, it minimizes maintenance costs by 30% compared to conventional solutions.
