Flexible duct made with AL/PET/AL wall (aluminum/polyester/aluminum) and harmonic steel wire spiral. Thermal insulating polyester fiber coating (25mm/16kg/m3 thickness). External protection in aluminized polyolefin film (fireproof). The resistance of the thermo-bonded polyester fiber prevents the dispersion of microfibers during air passage.
Insulation:
- 25mm / 16kg/m3 – standard
- 50mm / 16kg/m3 – on request
Thermal resistance at 20°C
- R = 0.58 m2 K/W (UNI EN 12664:2002)
