    Polyurethane Raw Materials for Sandwich Panel Production - Kimpur
    A PU sandwich panel is a building material with a polyurethane (PU) foam core sandwiched between two rigid outer layers, usually steel or aluminum sheets, creating lightweight, strong, and highly insulating panels used for walls, roofs, and cold storage, offering excellent thermal performance, fire resistance, and easy installation for industrial, commercial, and agricultural buildings.
     
    Key Components & Features
    • Core:
      Polyurethane (PU) foam, known for its low thermal conductivity, making it a superior insulator. 
    • Skins:
      Typically pre-painted steel or aluminum sheets, providing durability and weather resistance. 
    • Structure:
      The layered construction gives it high strength-to-weight ratio, making it sturdy yet light. 
    • Joining:
      Often features tongue-and-groove or hidden fastening systems for seamless, airtight installation. 
    Common Applications
    • Industrial Buildings: Warehouses, factories, logistics centers.
    • Commercial Spaces: Offices, retail outlets, gymnasiums.
    • Cold Storage: Walls and roofs for refrigerated warehouses and containers.
    • Transportation: Walls and roofs for trucks, trailers, ships, and RVs.
    • Agricultural: Barns, stables, and other farm structures.
    • Clean Rooms: Controlled environments in labs and manufacturing. 
    Benefits
    • Superior Insulation: Significantly reduces heating/cooling costs. 
    • Fire Resistance: Can be engineered for high fire safety requirements (PIR variants). 
    • Lightweight & Strong: Easy to transport and install, yet durable. 
    • Versatile: Available in various colors, profiles, and thicknesses. 
    • Fast Construction: Speeds up building processes due to large panel sizes and simple assembly.

      What is the disadvantage of a PU sandwich panel?
      2. Moisture Absorption: Sandwich panel walls can absorb moisture over time, which can cause the core material to deteriorate and weaken the overall strength of the panel. This can lead to structural problems in the building and a reduced lifespan for the panels.

      Which is better, rockwool or polyurethane foam?
      Rockwool vs PU Sandwich Panels – A Brief Comparison - EPACK ...
      Rockwool panels have a higher density, approximately 120 kg/m³, offering better sound absorption and structural rigidity in certain applications. PU panels are lighter, with a typical density of around 40 kg/m³, which contributes to ease of installation and reduced structural load.Oct 31, 2018
