Insulated Sandwich Panels for Roof, Wall, Cold Room and Clean Room Projects
LIAOHE insulated sandwich panels combine metal facings with insulation cores to form practical roof, wall, cold room and clean room building systems. The product range is designed for buyers who need thermal insulation, faster installation, cleaner project coordination and export-ready panel supply.
How This Panel Is Used
Use this category when the project is still in selection stage and you need to compare PU, PIR, rock wool, EPS, roof, wall, cold room and clean room panel options before confirming specifications.
Project fit
Use this category when the project is still in selection stage and you need to compare PU, PIR, rock wool, EPS, roof, wall, cold room and clean room panel options before confirming specifications.
Core material
PU, PIR, rock wool, EPS or project-specified insulation core
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
- Choose PU when insulation and weight control are the main requirements.
- Choose PIR when the project needs insulation with improved fire performance.
- Choose rock wool when fire resistance and acoustic performance are priorities.
- Choose EPS for cost-sensitive general construction where local code permits.
- Choose cold room or clean room systems when joints, surface finish and room details are more important than a generic wall panel.
