What is the quality of your insulation? (Temperature range for insulation) and Is the panels 100% filled with urethane?

We selected 100% of the new generation of pentane-blown B1 PU-PIR foam as the rigid core material, with excellent thermal insulation and fire resistance performance.

It boasts ultra-high temperature stability and a fire protection rating. It is also energy-saving and eco-friendly, with zero Freon emissions, thus being widely used in industrial buildings and cold storage projects.
