Handmade Polyurethane Sandwich Panel
Handmade polyurethane sandwich panels consist of two layers of high-strength panel material encasing a PU Foam core. The manufacturing process involves meticulous hand assembly, edge sealing, and pressing to create a high-performance composite sandwich panel. This handcrafted production process allows for greater flexibility in panel dimensions and surface treatments, making it ideal for both standard and custom applications.
Furthermore, they offer excellent sound insulation and fire resistance, meeting stringent building safety standards. These handmade polyurethane sandwich panels are widely used in logistics warehouses, factories, industrial buildings, commercial buildings, and residences—places where high levels of insulation and durability are required.

Benefits of Handmade Polyurethane Sandwich Panels
Thermal Insulation: Polyurethane material has an extremely low thermal conductivity (approximately 0.020-0.028 W/m·K), making it one of the best-recognized insulation materials currently available. It also effectively reduces building energy consumption and improves overall energy efficiency.
Flame Retardant Properties: The PU Foam core material possesses excellent flame-retardant properties. Combined with double-sided metal panels, the handmade polyurethane panel can meet building fire rating requirements of B1 or even higher.
Sound Insulation and Noise Reduction: The dense structure and high closed-cell rate of polyurethane foam effectively absorb and block sound wave propagation. Suitable for high-noise control applications, such as equipment rooms and laboratories.
High Strength and Wind Pressure Resistance: The double-sided metal facets of the handmade PU sandwich panels ensure the overall structural strength of the panels. The internal filling does not shrink or deform, maintaining stability even in windy areas or high-rise buildings.
Strong Sealing and Moisture-proof: With a closed-cell rate exceeding 95%, PU foam possesses excellent moisture-proof properties, preventing moisture ingress and effectively avoiding condensation and mold growth on walls. Ideal for clean spaces and cold storage areas with high humidity.
Installation Method for Handmade Polyurethane Sandwich Panels
Measurement and Layout: Lay out the installation positions on the construction site according to the design drawings.
Keel Installation: Lay the light steel keel system in place and secure it.
Panel Installation: Place the PU panels in sequence, ensuring tight joints.
Joint Sealing: Treat the joints with sealant or foam strips to ensure a tight seal.
Edge Finishing: Install aluminum alloy or stainless steel edge trims to enhance the overall aesthetics of the panels.
Cleanup and Acceptance: After completion, clean the surface and inspect the dimensional accuracy and joint tightness to ensure acceptance.
