Cold storage operation cost mainly comes from refrigeration power consumption, cold leakage caused by poor wall insulation wastes massive energy. Many cold room builders fail to select high performance insulation panels. This article focuses on PU sandwich panel’s unique insulation advantages for cold storage construction.

PU sandwich panel core material owns thermal conductivity lower than 0.023W per meter kelvin, far better than EPS and rock wool core panels. The dense foaming structure inside polyurethane blocks cold air penetration effectively. Thickened PU panels can lock low temperature inside cold room steadily, avoiding frequent startup of refrigeration units to save daily electricity cost.

Ordinary flat joint panels leave gaps for cold air leakage. PU cold room panel adopts double tongue groove interlocking design, filling connection gaps completely when splicing. The PU edge sealed structure prevents cold bridge at panel joints, solving the common frosting problem on cold storage wall surfaces caused by cold leakage.

High quality PU sandwich panel reaches B1 fire resistance grade to fit food cold storage and pharmaceutical cold room. The panel surface metal layer blocks flame spread outward when fire happens. Unlike flammable ordinary foam panels, PU panels slow down burning speed to win more evacuation and fire fighting time for cold storage operators.

PU cold room panel supports customizable thickness from 50mm to 200mm. Medium temperature cold storage above zero Celsius can choose 100mm panels. Low temperature frozen warehouse below minus 18 Celsius needs 150mm to 200mm thick PU panels. Customized size and color can be offered to match cold room internal partition and external wall layout demands.
