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

When choosing tunnel insulation boards, the following factors need to be considered: 1. Thickness: The thickness of the insulation board is closely related to its insulation effect. Generally speaking, the thicker the thickness, the better the insulation effect. But thickness is not the only factor to consider, other factors such as density and material also need to be taken into account. 2. Density: The density of tunnel insulation board is also an important factor to consider when selecting.
