What is NRC?
NRC stands for Noise Reduction Coefficient. This is the measurement of the amount of noise absorbed by a ceiling material. Recent changes in the building and standards guidelines means that planning for sound absorption is more important than ever. It is a myth that you can both absorb AND block noise using acoustic ceiling tiles. There is not enough mass in ceiling tiles to do both, plus the addition of things such as lights and vents make the task even more difficult.
Why is NRC important... read more

They also reduce the likelihood of the fire spreading throughout the entire building and damaging a much mor... read more

The two important properties to keep in mind when choosing acoustical ceiling panels are Noise Reduction Coefficient (NRC) and Ceiling Attenuation Class (CAC).
NRC refers to a surface’s ability to reduce noise by absorbing sound or the percentage of sound energy not reflected by the panel, which ranges from 0 to 1.0. The thickness and density of a product are two factors in calculating a Noise Reduction Coefficient. An acoustic ceiling product with a .95 NRC rating means that 95% of sound in the room is absorbed, wh... read more
The Skilled Labor Shortage
Looking back, 2017 will be the year that construction returned to the national spotlight, as infrastructure spending, pre-recession levels of construction activity and the skilled labor shortage dominated headlines.
