HUAYU PU Sandwich panel for factory buildings, storages, exhibition halls, gymnasiums, freezing stores, purifications workshops

A PU (Polyurethane) Sandwich Panel is a high-performance, prefabricated insulation panel composed of two external metal facings and a rigid polyurethane foam (PUR) core. They offer excellent thermal insulation, structural stability, and quick installation, making them ideal for modern construction and energy-efficient building solutions.

Core Advantages of HUAYU polyurethane Panels

Material:

1. Steel Sheet: up/bottom 0.3-1.2mm colored coated steel panel/ Zinc plate, hot galvanized plate/stainless steel plate

2. Core material: density of PU: 30-80kg/m3

Specification:

1.Cover width: 1000mm

2. Thickness: 50mm-150mm

Main Advantages

• ✅ Superior Thermal Insulation
  Low thermal conductivity (as low as 0.022 W/m·K) minimizes heat transfer, reducing energy costs.

• ✅ Excellent Fire Resistance
  Classified as B1/B2 (according to DIN 4102), PU foam slows down flame spread and resists ignition.

• ✅ Lightweight & Strong
  Combines high compressive strength with low weight, ideal for structures requiring minimal load.

• ✅ Moisture & Weather Resistance
  Closed-cell foam prevents water absorption and mold growth, ensuring longevity.

• ✅ Fast & Easy Installation
  Prefabricated interlocking system reduces construction time and labor costs.

• ✅ Attractive Finishes
  Various surface textures, colors, and profiles are available to meet architectural aesthetics.

Applications

PU sandwich panels are widely used in:

• Industrial Buildings

• Cold Storage & Refrigeration Facilities

• Commercial Buildings

• Modular & Prefabricated Homes

• Warehouse Enclosures

• Cleanrooms, Container Houses, and Transport Vehicles
