5. Additional Notes for PU Panel
The closed-cell structure of the rigid PU foam provides excellent moisture resistance and structural strength.
Panels are suitable for walls, ceilings, and roofs of cold storage, freezer rooms, and controlled environment chambers.
Foam Closed Cell Content: ≥95% (ensures low water absorption and stable long-term performance).
