Product introduction
Composite Wall Polystyrene PUR/PIR/PU Sandwich Panels are high-performance building materials consisting of an insulated polystyrene core sandwiched between two metal or structural facings, bonded with polyurethane (PUR), polyisocyanurate (PIR), or hybrid foam adhesives. These panels provide exceptional thermal insulation (thermal conductivity 0.022-0.028 W/mK), fire resistance (up to Class B1/A2), and structural stability while remaining lightweight. The composite construction ensures moisture resistance, soundproofing, and rapid installation for walls in industrial, commercial, and cold storage facilities. Customizable in thickness (50-200mm) and facing materials (galvanized steel, aluminum, etc.), they meet stringent energy efficiency and building safety standards.

Product advantages
☆PU Sandwich Panels Deliver Superior Thermal Insulation
PU sandwich panels achieve ultra-low thermal conductivity (0.022-0.028 W/mK), significantly cutting energy consumption in temperature-controlled buildings.
☆PU Sandwich Panels Provide Excellent Fire Protection
These panels meet strict Class B1/A2 fire ratings, offering critical safety for industrial facilities and storage units.
☆PU Sandwich Panels Combine Lightweight Design with Strength
Their composite construction maintains structural integrity while enabling faster installation than traditional materials.
☆PU Sandwich Panels Resist Moisture and Corrosion
The integrated waterproof core and protective facings withstand extreme weather and industrial environments.
Product application
PUR/PIR/PU Sandwich Panels are ideal for industrial warehouses, cold storage facilities, clean rooms, and commercial buildings. Their excellent thermal insulation (0.022-0.028 W/mK) and fire resistance (Class B1/A2) ensure energy efficiency and safety in pharmaceutical plants, food processing units, and temperature-controlled environments.
