Panel Sándwich PU de Aluminio
Aluminum PU sandwich panels combine two outer aluminum sheets with a rigid polyurethane (PU) foam core in a three-layer structure. The aluminum skins, typically 0.3-1.0 mm thick, are available in various alloys and can receive surface treatments such as fluorocarbon coating or anodizing. The PU foam core, with density commonly between 28-80 kg/m³, provides low thermal conductivity. Total panel thickness ranges from 10-120 mm, with standard widths up to 2600 mm and lengths reaching 12 meters.
The PU foam core delivers effective thermal insulation, reducing heat transfer and maintaining stable indoor temperatures for energy efficiency. The aluminum skins provide structural strength, corrosion resistance, and protection from rain and wind. The panels are lightweight, facilitating handling and installation, and both aluminum and polyurethane are recyclable materials.
Applications include cold storage rooms, refrigerated warehouses, and transportation vehicles such as refrigerated trucks, trailers, and ships where thermal insulation is critical. In building construction, the panels serve as exterior and interior wall cladding, roof panels, and facades for industrial, commercial, and agricultural structures.
The panels can be cut and shaped using high-precision Computer Numerical Control (CNC) machining. Many systems feature interlocking or snap-lock mechanisms for concealed fastening, creating a sleek appearance with hidden fixings. Customization options include dimensions, color, surface finish, and core density.
