AL THERM
Flexible duct made of AL/PET/AL (aluminum/polyester/aluminum) and harmonic steel wire spiral. Thermal insulation layer in polyester fiber (25 mm / 16 kg/m³). Outer protection in aluminumized polyolefin film (flame retardant). The strength of the thermobonded polyester fiber prevents the dispersion of microfibers during airflow.
Insulation:
25 mm / 16 kg/m³ standard
50 mm / 16 kg/m³ on request
Thermal resistance at 20°C
R = 0.58 m² K/W (UNI EN 12664:2002)
