KCL 48

KCL 48® is a glass wool-based insulation duct liner for air-conditioning, ventilation and heating and cooling systems. KCL 48® offers superior acoustic comfort, thermal performance, and high level of airtightness to keep your air fresh and making the system energy efficient. 

KCL 48® reduces noise levels generated by fans and air-conditioning units providing superior acoustic comfort to the building occupants. 

KCL 48® is highly absorbent, including at low frequencies, where the problem of noise generated by the AHU or ventilation machine is greater.
