Polyurethane Composite Panels| Joint Corner Panel

Polyurethane composite panels features

Fire Retardant

The PU foam core quickly carbonizes under heat, preventing the spread of fire and enhancing safety.
Compressive Strength

High compressive strength ensures the polyurethane cold room panels' resistance to distortion and maintains its shape under pressure.
Sealing Performance

Excellent sealing performance minimizes air leakage and heat loss, enhancing energy efficiency.

Easy Installation and Maintenance

Our freezer panels are designed for ease of installation and maintenance, reducing construction time and costs.
Weather Resistance and Long Lifespan

Being weather-resistant, our insulated freezer panels are suitable for outdoor applications and offer a long service life.
Versatility

The panels for cold room can be easily cut and shaped to fit specific design requirements, making them highly adaptable.

Joint Corner Panel — Seamless, Thermal-Bridge Free Corner Solutions

Our Joint Corner Panel is a prefabricated, insulated corner solution designed to eliminate traditional corner joints and reduce thermal bridging in industrial and refrigerated buildings. Available in PIR and PU cores, the joint corner panel is ideal for cold storage, cleanrooms, food processing facilities, warehouses, and factory buildings. This one-piece or precision-spliced corner system dramatically speeds installation and improves long-term airtightness and hygiene.

These polyurethane composite panels consist of a polyurethane foam core laminated between two layers of galvanized steel, offering a splicing design for versatile applications. Our sandwich board panels are engineered to be lightweight, durable, and easy to install, making them ideal for a wide range of construction and insulation needs.

· Thermal-bridge free corners — engineered to minimize heat loss at external and internal corners, improving overall building energy performance.
· Hygienic one-piece options for cleanrooms and food plants — integrated corner systems remove crevices where dust and bacteria collect, simplifying cleaning and helping meet stringent hygiene requirements.
· Faster installation & fewer accessories — factory-made corner elements reduce on-site cutting, flashing and sealant work, saving labour and reducing installation risk.
· Multiple core choices & fire performance — choose PIR (superior thermal conductivity) or PU cores and specify fire ratings and surface finishes per project needs.

Typical Applications

· Cold storage rooms & freezers (joint corner panel for cold storage)
· Cleanrooms and pharmaceutical facilities (hygienic one-piece corner solutions)
· Warehouses & logistics centers (insulated corner panels for external walls)
· Food processing plants (wipe-clean corners)
· Prefab modular buildings and refrigerated trucks

Available Types & Edge Details

· Integrated one-piece corner panel (factory molded) — eliminates corner splice; best for hygienic cleanroom and cold storage applications.
· L-shaped corner panel — economical solution for standard 90° corners.
· Joint corner panel (spliced) — for large panels where transport length or onsite splicing is required; designed to achieve airtight cam-lock or tongue-and-groove connections.
· Radius / arched corner systems — for curved façade or architectural detailing.
