Insulation Sleeve

Thermal Insulation Jacket

The insulation jacket consists of an aluminium laminate outer jacket and provided with a glass wool insulation layer.

The thermal insulation is suitable for preventing condensation and minimizing heat loss and loss of cold.

Ducting Insulation Sleeve









  • Insulation in air supply systems
  • Reducing of heat loss
  • Preventing/discharging of condensation



The insulation jacket has standard a barrier. The barrier simplifies the mounting, and the installer will not have unnecessary contact with the glass wool.
