What is the sound absorption (NRC or αw) of your ceilings?
The sound absorption of the ceiling can be expressed in both NRC (ASTM - C423) and αw (ISO 11654). The higher the value, the better the sound absorption. For both NRC and αw, the value can vary between 0.70 and 0.95, depending on the ceiling type, climate system and the acoustic package. Inteco has had the sound absorption of dozens of variants at Peutz examined. We advise you to contact our sales department so that we can provide you with a project-specific answer.
