What Determines the Temperature Resistance of Polyurethane Insulation Panels?

Jan 21, 2024

Leave a message

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

PU COLD STORAGE PANEL

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.
