In building ventilation and industrial exhaust systems, the thermal insulation and durability of ductwork directly impact system efficiency, and closed-cell perlite provides crucial support for improving duct performance.
The hollow structure of closed-cell perlite, encasing air within, results in low thermal conductivity. When incorporated into ductwork materials (such as duct insulation layers and composite duct substrates), it forms a highly efficient insulation layer. In summer, it reduces the transmission of high external temperatures into the duct, preventing cool air loss; in winter, it prevents the dissipation of warm air from within the duct, reducing energy consumption in air conditioning and heating systems and contributing to energy-efficient operation.
