Comparison between PIR sandwich panel and PU sandwich panel

PIR sandwich panels and PU sandwich panels are common building materials. They have excellent properties in terms of thermal insulation, heat insulation, and lightweight. This article will compare the performance, characteristics and application areas of these two sandwich panels in detail to better understand their differences and advantages.

1. Performance comparison

Thermal insulation performance: PIR sandwich panel has high thermal insulation performance because its internal closed-cell structure can effectively reduce air convection and reduce the thermal conductivity coefficient. Although PU sandwich panels also have certain thermal insulation properties, they are slightly inferior to PIR sandwich panels.

Thermal insulation performance: The thermal insulation performance of PIR sandwich panel is better than that of PU sandwich panel because its closed-cell structure can reduce heat transfer and provide better thermal insulation effects.

Lightweight performance: Both sandwich panels have lightweight characteristics, but PIR sandwich panels are lighter and easier to transport and install.

2. Comparison of features

Fire resistance: PIR sandwich panels have good fire resistance and can meet B1 fire protection standards, while PU sandwich panels have relatively poor fire resistance.

Environmental performance: PIR sandwich panel use fluorine-free foaming technology during the production process, which is environmentally friendly. The PU sandwich panel will produce certain waste gas, waste water and other pollutants during the production process.

3. Comparison of application areas

PIR sandwich panels are widely used in building insulation, refrigerated trucks, cold storage, air conditioning ducts and other fields, and are favored for their excellent thermal insulation, heat insulation and fire protection properties.

PU sandwich panels are more commonly used in temporary buildings, industrial plants, warehouses and other construction fields that require lightweight and easy installation.

To sum up, PIR sandwich panels and PU sandwich panels have their own advantages in performance, characteristics and application fields. PIR sandwich panels have better performance in thermal insulation, heat insulation and fire resistance, and are suitable for areas with higher requirements for insulation and fire resistance; while PU sandwich panels are more suitable for construction areas that require lightweight and easy installation. When selecting, the appropriate sandwich panel type should be selected based on specific needs and scenarios.
