One of the main sources of energy loss in cold storage rooms is inadequate insulation. Choosing the right panel thickness and polyurethane density is key to minimizing heat transfer and reducing electricity consumption.

✅ Recommended Panel Thickness by Internal Temperature:

These values ensure optimal thermal insulation and system efficiency at various storage temperatures.

✅ Opt for High-Density Polyurethane

The insulation core of cold room panels is typically made from polyurethane (PUR). For maximum energy efficiency, the ideal density is 42 kg/m³. This density represents the peak point on the insulation performance curve, offering the highest thermal resistance (lowest heat conductivity).

⚠️ Important Note: Although many manufacturers list “42 density” in their offers, this is not something end users can verify without special testing. Therefore, it is critical to work with transparent and trustworthy manufacturers who can guarantee actual material performance.

✅ Seal All Connections

• Panel joints must be fully sealed to avoid thermal bridging and air leakage.

• Use PVC strip curtains or automatic rapid doors to reduce warm air exchange during door openings.
