Reliable Waterproof Backing Board for Effortless Installation and Use

Yes. Our factory operates under the ISO 9001 Quality Management System. Our insulation products, including rock wool boards and tile backer boards, are CE certified and comply with relevant ASTM standards. We can provide full test reports and certificates upon request to ensure your projects meet local regulations and building codes.

Our products excel in both thermal efficiency and fire safety. Thermal Performance: The thermal conductivity (K-value) ranges from 0.028 W/(m K) to 0.040 W/(m K), depending on the product type and density. This ensures excellent insulation performance. Fire Rating: Most of our insulation materials, such as rock wool, are classified as Class A non-combustible, helping significantly improve building fire resistance.

We offer flexible terms to meet different customer needs. MOQ: For standard products, the MOQ is typically one 20-foot container (20GP). Mixed container and trial orders are also supported. Samples: Free samples are available for quality evaluation. You only need to cover shipping costs, and the sample cost can be deducted from your first order.

Quality control is integrated into every stage of production. Raw Materials: All suppliers are strictly evaluated and materials are inspected upon arrival. Production: Automated lines and experienced workers monitor key parameters such as density and thickness in real time. Final Inspection: Each batch undergoes a strict pre-shipment inspection. Third-party inspections are also supported for added assurance.
