Ourgreen B1 Grade Fire Resistant XPS Foam Board for Cold Storage
Thickness Requirement of Nanjing Ourgreen XPS Foam Board
When XPS is installed for building insulation, as being used together with Roof / Wall / Floor, a thickness of less than 50mm is enough.
In area such as Cold Chain Logistic Truck manufacturing, Cold Storage, Insulation board at thickness of 75mm / 100mm or more is preferred. Especially in Cold Storage, where release of cold is critical. People tend to require large panel like 2440X1220X100mm or even 2440X1220X150mm. In this case XPS Extrusion Line with small capacity is far from enough. Bigger Extruder with higher capacity of 800-1500 Kg/h is expected.

XPS Foam board has to meet fire classification requirement of at least B2 Grade in China. According to China National Standard GB/T 2406.2, B2 Grade corresponds to an Oxygen Index of > 26% while B1 Grade corresponds to and Oxygen Index of >30%.
