The use of rubber has the following advantages:
- reduces vibration, absorbs sounds that occur in the ventilation ducts
- avoid the appearance of condensation, freezing and freezing, because this can lead to the formation of cracks and destruction of air ducts
- the loss of thermal characteristics of the air is reduced
- saving from rusting of vent channels.
In addition to the sheet insulation, a rubber tape
was used to glue the joints.
