	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.	0.60
	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.	33
