K-13"fc" effectively provides the acoustic control necessary to manage the noise level and reverberation created by the massive volume of the atrium and the various activities occurring within it. At the same time, K-13"fc" gives the atrium ceiling an appealing texture which enhances the overall visual effect of the building's design.

To match the decor and fit within the Egyptian theme of the resort, a special color of K-13"fc" (Desert Beige) was specifically matched for this project. The Desert Beige K-13"fc" was spray applied to the cantilevered concrete balconies which make up the ceiling of the atrium.

A one inch thick application of K-13"fc" provides an NRC of .90 for the middle seven balconies, where acoustics were determined to be the most critical. The upper and lower balconies were treated with a half inch thick application of K-13"fc" to provide an NRC of .65. In addition to the Luxor's atrium, 30,000 square feet of K-13 Black was applied to the ceiling of the Luxor's arena which is on a level below the atrium.
