Purchasing Guide

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

  • For procurement requirements that require the use of insulation materials, it is recommended to first clarify key technical parameters such as thermal conductivity and fire resistance rating. There is a significant difference in material performance requirements between industrial high-temperature pipelines and building exterior walls.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. For example, companies that have long served in the petrochemical or new energy fields usually have a better understanding of special insulation needs.
  • When evaluating different application scenarios, flexible insulation felt is commonly used in cold chain logistics, while ceramic fiber board is commonly used in metallurgical equipment. Before procurement, the material form and installation method need to be confirmed based on specific working conditions.
  • The procurement volume in the construction field is large and the cycle is stable. Attention can be paid to the supplier's production capacity guarantee and regional warehousing capacity, while comparing the actual insulation efficiency data of similar project cases in the past.
