Polyurethane insulation panels are widely adopted for cold‑storage, freezer rooms and industrial building envelopes. Their temperature resistance, thermal performance and physical parameters directly determine project energy‑saving efficiency and long‑term service life.
Core Panel Construction
Well‑manufactured PU sandwich panels consist of metal outer facings bonded firmly to rigid polyurethane foam core.
Exterior Sheets: 0.5 mm PPGI steel sheets
Insulation Core: Rigid Polyurethane (PU) Foam
Custom‑available Thickness: 50 mm‑250 mm
PU Foam Density: 40‑42 kg/m³

Standard Panel Dimensions
Our PU insulation panels are produced in container‑friendly maximum lengths to lower logistics costs for overseas shipments.
Standard Working Width: 1120 mm
Maximum Production Length: up to 11.85 m

Thermal Performance Data
Low thermal conductivity is the core advantage of PU insulation material. The thermal resistance (R‑value) increases as panel thickness grows.
Core Thermal Conductivity (λ): 0.021 W/(m·K) ‑ Thermal Resistance reference by thickness:

Additional Technical Notes for PU Insulation Panels
Rigid PU foam features a high‑rate closed‑cell structure, delivering excellent moisture resistance and mechanical strength.
Closed‑cell content ≥95 %, which keeps low water‑absorption rate and stable long‑term insulation performance. ‑ Typical applications: Walls, ceilings and roofs for cold‑storage rooms, freezer rooms, and controlled‑environment chambers.
For cold‑room or industrial construction projects, select proper panel thickness based on target operating temperature. If you need technical support or custom quotation, feel free to send us your project requirements.
