Product description

CLIMAVER® is a glasswool based pre-insulated duct system for air-conditioning, ventilation and heating and cooling systems. CLIMAVER® offers superior acoustic comfort, thermal performance and high level of airtightness to keep your air fresh and making the system energy efficient.

CLIMAVER® Neto reduces noise levels generated by fans and air-conditioning units providing superior acoustic comfort to the building occupants.

CLIMAVER® is highy absorbent, including at low frequencies, where the problem of noise generated by the AHU or ventilation machine is greater

                         Typical example: Acoustic attenuation in dB for 5m of 400x200mm duct

Product Frequency (Hz)
125 250 500 1000 2000
Metal duct 2 2 7.5 7.5 3
CLIMAVER® Plus 8.5 8.5 8.5 38.5 30
CLIMAVER® Neto 18 43 52.5 62.54 68
  • Increases the level of acoustic comfort of your buildings
  • No need for additional acoustic insulation liners inside the ducts
  • No need for silencers or sound attenuators (depends on system design)
