White PVC Waterproof Membrane 1.2mm, 2m Width, 85% Light Reflectivity, Low VOC, for Green Roof
Product Spotlights
Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998, exporting high-quality construction materials to over 15 global markets. Our White PVC Waterproof Membrane (1.2mm thickness, 2m width) is specifically engineered for green roof systems, combining superior waterproofing with an impressive 85% light reflectivity and low VOC emissions. This product is designed to meet the growing demand for sustainable and energy-efficient building solutions, offering a perfect balance of performance and environmental responsibility.
As a factory with over two decades of experience, we understand the critical requirements of modern roofing projects. Our PVC membrane is produced using advanced calendering technology, ensuring uniform thickness, high tensile strength, and excellent flexibility. The white surface reduces heat island effect, lowers cooling costs, and protects the roof membrane from UV degradation. With low VOC content, it contributes to better indoor air quality and meets stringent environmental standards.
Key Features & Technical Specifications
- Waterproof & Durable: 100% waterproof PVC formulation, resistant to root penetration, chemicals, and harsh weather conditions.
- High Reflectivity: 85% solar reflectance (SRI ≥ 85) helps keep roof surfaces cool, reducing energy consumption for air conditioning.
- Low VOC: Volatile organic compound content is below 50 g/L, making it safe for green roof vegetation and indoor environments.
- Easy Installation: Flexible and lightweight (approx. 1.8 kg/m²), can be installed with hot air welding or adhesive bonding.
- UV Resistance: Stabilized against UV radiation, ensuring long service life (expected 20+ years under proper maintenance).
- Environmentally Friendly: Recyclable material and low carbon footprint during production.

Frequently Asked Questions (FAQ)
1. Can this membrane be used on sloped roofs?
Yes, it is suitable for both flat and sloped roofs (up to 30°). For slopes over 30°, additional mechanical fastening may be required.
2. Is it compatible with all types of green roof vegetation?
Absolutely. The membrane is root-resistant and works well with sedum, grasses, and small shrubs. It can be paired with a root barrier if needed.
3. How do you install the membrane?
Installation can be done via hot air welding (for seams) or fully adhered with a compatible adhesive. Detailed installation guidelines are provided.
4. What is the expected lifespan?
Under normal conditions, the membrane lasts 20–30 years. UV stabilizers and high reflectivity help extend its service life.
5. Does it contain any harmful chemicals?
No. Our PVC membrane is formulated with low VOC content (
6. Can you provide a sample before bulk order?
Yes, we offer free samples (A4 size) for testing. Shipping cost is at buyer's expense.
7. What is the minimum order quantity (MOQ)?
Standard MOQ is 500 m² (5 rolls). For special colors or thickness, MOQ may be higher.
8. How do you package the membrane for export?
Each roll is wrapped in polyethylene film, then packed in a woven bag or wooden crate to prevent damage during transit.
