Description

INSULATION

The Aluflex core is wrapped in 200 gram/m2 polyester fiber insulation which is held in place with an aluminium jacket. The aluminium jacket also gives it an extra vapour barrier.

JACKET

The Aluflex jacket is constructed with 2 layers clear polyester on the inside and an aluminium layer on the outside. The aluminium on the outside gives it its fire rating.

APPLICATION

The Aluflex flexible ducts are used in ventilation, air conditioning, and air handling systems where high mechanical strength, temperature and fire resistance is required.
