flexible ducts: isulated
SONODEC 25 thermally and acoustically insulated duct
High quality, flexible ducts, which are used in low and medium pressure ventilation and air conditioning systems. The flexible design minimizes the number of fittings needed to make complex installations, which significantly reduces the cost of its implementation.
Outer shell made of one layer of aluminum, and two polyester layers. The inner channel consists of three aluminum layers and two polyester layers. The insulation layer is 25 mm thick glass wool. The inner channel additionally has a veil made of a vapor permeable foil.
The insert is ALUDEC CLASSIC type cable densely perforated along the entire length of the cable.
Ducts have Polish Hygienic Certificate HK / B / 0919/02/2009.
A product of the renowned Dutch company DEC International.
The duct is insulated both thermally and acoustically.
