PU Sandwich Panels for Thermal Insulation and Cold Room Projects
PU sandwich panels are selected for projects where thermal insulation, lightweight construction and fast installation are central to the buying decision. A rigid polyurethane core helps reduce heat transfer, while metal facings protect the panel surface during daily building use.

How This Panel Is Used
They are especially useful for cold rooms, refrigerated warehouses, food processing facilities, workshops and industrial buildings that need reliable insulation without excessive wall or roof weight.
Project fit
They are especially useful for cold rooms, refrigerated warehouses, food processing facilities, workshops and industrial buildings that need reliable insulation without excessive wall or roof weight.
Core material
Rigid polyurethane foam
Export support
Panels can be supplied with customized length, surface color, packing method and shipment documents according to order requirements.
Panel Structure and Materials
The panel is built as a composite system: outside steel facing, insulation core, inside steel facing and a connection detail selected for the building use. This structure helps buyers coordinate insulation, strength, appearance, installation speed and maintenance in one product.
For export projects, please confirm core material, panel thickness, steel sheet thickness, coating, color, length, quantity, joint type and packing requirements before production.

How to Choose Specifications
- For general warehouses, 50 mm to 75 mm panels are commonly considered, depending on climate and energy targets.
- For chill rooms and processing areas, 75 mm to 100 mm is often evaluated first.
- For freezer or low-temperature rooms, thicker PU panels may be required according to temperature, room size and door openings.
- Confirm steel thickness and coating according to indoor humidity, cleaning method and external environment.
