4mm Sbs Modified Bitumen Waterproofing Asphalt Roofing Membrane for Building Roof

4mm Sbs Modified Bitumen Waterproofing Asphalt Roofing Membrane for Building Roof. Superior Waterproof Barrier: SBS membrane prevents water infiltration (0.3MPa/30min) for roofs, tunnels, and bridges. No Complex Installation: Pre-fabricated torch-on membrane installs fast without special equipment. 500N/50mm Tensile Strength: High resistance to mechanical damage and cracking under load. -25C to 105C All-Weather: Flexible at -25C (no cracks) and stable up to 105C. 0.3MPa Impermeability (30min): Exceeds industry standards for certified water-tightness. Flexible at Low Temps: Retains flexibility and shows no cracks at temperatures as low as -25C. UV & Aging Resistant: Maintains performance under prolonged sunlight exposure, ideal for exposed roofs. Eco-Friendly & Safe: Free from harmful solvents, meets EU environmental standards for green building.
