Pu Sandwich Wall Panel

Premium thermal insulation: Low thermal conductivity of PU enables PU sandwich wall panels to perfectly fit cold storage, constant-temperature and energy-saving industrial buildings; pairing with matching panel roofs optimizes overall building insulation.
Stable robust structure: Tight bonding between rigid PU core and metal skins brings outstanding compression and wind resistance as well as long-term structural stability.
Efficient installation & labor savings: Prefabricated design speeds up construction, cuts labor input and total project expense, advantageous for large B2B construction projects.
Energy and operational cost saving: Effective heat blocking lowers HVAC power consumption, decreases running costs, boosts building efficiency and shortens investment payback period.
Lightweight advantage: Lighter than brick and concrete, the panels ease foundation burden, simplify transportation and lift installation efficiency.
Customizable fireproof property: PIR or modified PU cores are available upon request to satisfy different fire safety specifications.
Long-lasting anti-corrosion performance: Pre-coated steel/aluminum outer layers resist corrosion and harsh weather, supporting a service life over 20 years.

Product Details

PU sandwich wall panel boasts superior thermal insulation ideal for cold storage and industrial premises when paired with panel roofs. Its bonded PU core ensures high structural strength; lightweight prefabricated construction cuts transport, labor and operational costs and speeds up ROI. Custom PIR/modified PU cores meet fire standards, and coated metal skins offer corrosion resistance with over 20 years’ lifespan.

1. Structure of PU Sandwich Wall Panel

The PU sandwich wall panel consists of three layers:

Outer Layer: Pre-painted galvanized steel (PPGI/PPGL) or aluminum
Core Material: Rigid polyurethane (PU) foam
Inner Layer: Steel sheet or aluminum foil

This structure provides excellent insulation, strength, and durability.

3. Applications

PU sandwich wall panels are extensively applied in industrial warehouses, cold storage, food processing plants, pharmaceutical workshops, cleanrooms, prefab container homes and agricultural constructions. Installed alongside matching pu sandwich panel roofs, they create a fully insulated integrated building enclosure.

4. Installation System

Our PU sandwich wall panels adopt tongue-and-groove connections and concealed fixing structure to deliver superior airtightness and waterproofing. Compatible with steel frames and modular constructions, they enable quick, streamlined installation to shorten construction cycles effectively.
