Durable PIR Sandwich Panels for Reliable Cold Storage Applications

Its long-term value is mainly reflected in three aspects: better fire safety reduces insurance and risk costs; lower long-term thermal conductivity brings significant energy-saving benefits; higher dimensional stability reduces maintenance needs, making the comprehensive cost throughout the life cycle more advantageous.

A dedicated eccentric hook lock or tongue and groove insertion system is adopted, combined with low-temperature elastic sealant. This design can maintain tight interlock when the sheet shrinks due to temperature differences, achieving dual physical and chemical sealing and effectively preventing cold bridges and cold leakage.
