Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of polyurethane edge sealing rock wool board, it is recommended to prioritize checking key parameters such as product thickness (usually 50-200mm), fire rating (such as Class A), and thermal conductivity (≤ 0.040W/(m · K)) to ensure compliance with technical requirements for building wall or roof insulation scenarios.
  • Polyurethane edge sealed rock wool board is suitable for industrial plants, cold chain warehouses and other scenarios with high requirements for fire prevention and insulation performance. When purchasing, its compressive strength (≥ 40kPa) and hydrophobicity (≥ 98%) can be evaluated based on specific application environments.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support or platform statistical information. Such suppliers usually provide more stable product delivery capabilities.
  • When using polyurethane edge sealing rock wool board in cold storage construction, attention should be paid to the integrity of its edge sealing process (such as polyurethane tape width ≥ 20mm) to avoid the thermal bridge effect affecting the overall insulation performance.
