Product Introduction

Our low price soundproof wall PU sandwich panels are designed to tackle two common problems in cold rooms and clean rooms: excessive noise from compressors and fans, and high costs of traditional acoustic insulation materials. By combining a high‑density polyurethane (PU) core with rigid steel facings, these panels effectively reduce noise transmission while maintaining excellent thermal insulation. They prevent condensation, energy loss, and cross contamination in temperature,sensitive environments.

Applications include food cold storage, pharmaceutical cold chain warehouses, electronic cleanrooms, laboratories, operating theaters, and any industrial facility that requires both noise control and temperature stability.
