Because of it’s extremely high barrel ceilings, 28′ high at the apex, the vct floors and hard gypsum surfaces throughout the space, the main study areas of the building had a terrible echo problem, one of the worst cases we have ever run across. The solution was to furr out the upper sections of the exterior and interior walls with 2 x 4 wood framing, unfaced fiberglass insulation and 1″ Tectum panels which were pre-painted in a soft teal green with some panels a darker green for accent. We succeeded in obtaining a Noise Reduction Coefficient rating of .85 which is very high. The NRC rating of a standard 5/8″ painted gypsum wall is .05. The City of San Antonio was extremely happy with the results.
