Acoustics
Acoustical options available. |

|---|---|
|
Sound Absorption (NRC)
A measure for rating the overall sound absorption of a material when used in an enclosed architectural space where sound is reflected at many angles of incidence. A ceiling system with an NRC < 0.50 is low performance, an NRC > 0.70 is high performance. |
0.80 |
|
Sound Blocking (CAC)
A measure for rating the performance of a ceiling system as a barrier to airborne sound transmission through a common plenum between adjacent closed spaces. A ceiling system with a CAC < 25 is considered low performance, whereas one with CAC of 35 or higher is high performance. |
35 |

Articulation Class (AC)
Product has AC (Articulation Class) 170 or greater. |

Light Reflectance
A high light reflective ceiling – LR 0.83 or greater, per ASTM E1477-98 as referred to in ASTM E1264-98 – makes lighting systems, especially indirect lighting, more effective while further reducing energy costs and consumption. LR values apply to White panels only. |
