SONOFLEX PRO thermal and acoustically insulated flexible duct

Duct

The duct consists of an inner perforated channel made of laminated aluminum, reinforced with a corrosion-resistant steel spiral. Between the inner channel and the glass wool insulation is a vapor-proof film that prevents moisture contained in the air from entering the insulation. The outer jacket is made of polyester-reinforced aluminum.

Wool

The glass mineral wool used in Sonoflex PRO cables produced with the innovative ECOSE® fiber bonding technology, does not contain the addition of harmful chemicals commonly used in other insulation products. The brown color of the wool is a natural shade created during its production. No artificial dyes or brightening agents are used in the production process.
