Purchasing Guide

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

  • For procurement needs that require the use of polystyrene insulation boards, it is recommended to prioritize confirming key technical parameters such as thermal conductivity, compressive strength, and fire rating to ensure that insulation requirements for different scenarios such as building exterior walls or cold storage are met.
  • 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 can usually provide more stable product supply.
  • In industrial plants or civil construction projects, the thickness and density of polystyrene insulation boards need to be selected according to actual insulation needs, and there may be differences in product specifications in different climatic regions.
  • It is recommended to conduct a comprehensive evaluation based on the industry performance and product compatibility of suppliers during procurement. For example, enterprises that have been serving large infrastructure projects for a long time may be more familiar with application standards in complex scenarios.
