Cold insulation materials are functional materials used to reduce heat transfer from the surrounding environment to low-temperature media, pipes, equipment, or storage tanks. Their purpose is not simply to “keep things cold,” but to reduce heat transfer and help control the thermal load of a system. When combined with vapor barriers and protective layers, a properly designed cold insulation system can also help reduce the risk of condensation, frosting, and moisture entering the insulation layer.
Cold insulation is a system, not simply a single material. Insulation layers, moisture control, protective layers, supports, joints, and installation quality all contribute to the final performance.
Different insulation materials have different compositions, structures, and application conditions. Therefore, there is no single material suitable for every low-temperature system.
Cellular Glass is an inorganic insulation material with a uniform closed-cell structure. Its glass-based composition and closed-cell structure provide low thermal conductivity, low water absorption, and good compressive performance, along with non-combustible characteristics.
According to product information, relevant Cellular Glass products can be used for insulation of low-temperature and cryogenic pipes, vessels, storage tanks, and equipment. High-performance products complying with ASTM C552 are available in different density and compressive strength grades to meet specific project requirements.
PIR is a rigid foam insulation material with low thermal conductivity and a closed-cell structure. Its specific operating temperature, mechanical properties, and fire performance depend on the product design and applicable technical specifications.
In industrial insulation, PIR can be used for pipes, equipment, and other low-temperature systems. Its suitability should be determined according to operating conditions and project requirements.
PUR is also a rigid foam insulation material. Its closed-cell structure and low thermal conductivity make it suitable for certain low-temperature insulation applications.
For PUR, the material name alone should not be used to determine its suitability. Specific product data, including operating temperature, thermal conductivity, water absorption, dimensional stability, and other technical parameters, should be reviewed before selection.
Fiberglass is a fiber-based insulation material that can be used for industrial pipes, equipment, and related insulation systems. Compared with closed-cell foam materials, its moisture protection requirements need to be considered together with the specific product structure and vapor barrier system.
Therefore, for low-temperature applications, fiberglass should not be selected based only on its insulation performance. Moisture control, installation methods, and external protection should also be evaluated.
Cold insulation materials reduce heat transfer from the surrounding environment to low-temperature media, pipes, and equipment, helping control the thermal load of the system.
A properly designed cold insulation system can help reduce the risk of condensation and frosting caused by cold surface temperatures.
Certain cold insulation materials can be used in low-temperature and cryogenic environments, including LNG systems, low-temperature piping, and related industrial equipment.
Materials with suitable mechanical strength can help withstand mechanical loads encountered during the operation and installation of an insulation system.
Different insulation materials offer different combinations of thermal conductivity, moisture control, fire performance, mechanical strength, and temperature capability, allowing insulation systems to be designed according to specific project conditions.
LNG storage tanks, cryogenic piping, and related equipment require insulation systems to reduce heat transfer from the surrounding environment. Materials such as Cellular Glass can be used for appropriate low-temperature insulation applications based on design temperature, mechanical loads, and system configuration.
Refineries, chemical plants, and other industrial facilities contain numerous low-temperature pipes and equipment. Cellular Glass, PIR, and PUR can be selected for different applications according to operating conditions, equipment configuration, and project specifications.
Refrigeration equipment and cold storage facilities need to reduce external heat transfer and control the risk of condensation on cold surfaces. PIR, PUR, Fiberglass, and other insulation materials can be configured according to the specific structure, operating temperature, and moisture protection requirements.

There is no single material that is best for every project. Selection should consider design temperature, thermal conductivity, moisture control requirements, compressive performance, fire requirements, and applicable project standards.
Yes. Relevant Cellular Glass products can be used for insulation of low-temperature and cryogenic pipes, vessels, storage tanks, and equipment.
Selection should consider design temperature, thermal conductivity, moisture control, mechanical loads, fire performance, dimensional stability, applicable project standards, and installation conditions rather than focusing on only one performance parameter.
Material properties vary by product type and manufacturer. For engineering applications, always verify product technical data, applicable standards, design temperature, system configuration, and installation requirements before specifying insulation materials.
