Purchasing Guide

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

  • For procurement requirements that require the use of insulation boards, it is recommended to prioritize confirming key technical parameters such as thermal conductivity, fire rating, and thickness range, which directly affect building energy efficiency or the insulation effect of industrial equipment.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. These suppliers usually have more stable delivery capabilities in sub fields such as cold chain logistics or exterior wall insulation.
  • In low-temperature storage or pipeline insulation scenarios, different materials of insulation boards need to be selected based on environmental humidity and temperature differences. For example, extruded polystyrene boards are suitable for high humidity environments, while rock wool boards are more suitable for high-temperature fire protection needs.
  • When purchasing insulation boards, it is usually necessary to pay attention to the industry data support of suppliers, and evaluate the actual application cases of their products in large-scale infrastructure projects based on platform statistical information, in order to reduce procurement risks.

Knowledge Base

Q

How to choose rock wool insulation board for ship steel structure 1. Expansion type A-grade fireproof rock wool board should not be used outdoors. The expansion type A-grade fireproof rock wool board was originally used for wooden structures. Due to its poor weather resistance outdoors, it is prone to aging and peeling, and has reliability issues with expansion in humid and corrosive environments. In addition, during the high-temperature flame grilling and foaming process, resin decomposition produces thick smoke and toxic gases,
