Cold Store Sandwich Panels（冷库夹芯板 / 冷藏夹芯板） are specialized sandwich panels designed for cold storage or refrigeration buildings. Their primary role is to maintain thermal insulation, moisture control, and structural integrity under temperature differentials.

Key Requirements

• Extremely low thermal conductivity: to minimize heat leaks.

• Good vapor barrier and tight joints to prevent condensation, frost, and moisture ingress.

• Panels must withstand repeated thermal cycling (seasonal temperature changes).

• Joint sealing with gaskets or specialized seals to ensure airtightness.

Structure & Materials

• Often use high-performance cores like PIR or high-density PU.

• Facing layers often include corrosion-resistant metal (e.g. coated steel, aluminum) to resist humidity and cold.

• Panel joints often are tongue-and-groove or interlocking systems with gaskets to ensure tightness.

Usage Scenario
Cold storage rooms, freezer rooms, refrigerated warehouses, food processing industries, pharmaceutical cold rooms, etc. These panels are critical to energy efficiency and maintaining required low-temperature environments.
