ALUDEC 112 ducts are flexible, strong laminate ducts for various purposes. The ducts consist of several layers of aluminium and polyester, with a high tensile steel spiral helix enclosed between the layers. The duct can be attached to round and oval connection parts without any problems.
The fire resistance of the ALUDEC 112 ducts has been tested in several countries, according to current international standards. Because of the “sandwich construction”, the different layers of polyester and aluminium are overlapping each other completely. In case of fire, the system is able to function longer.
