On 11/29/2021, Avalon International Aluminum introduced the Eagle Tacitus Frame System to Riverbank Acoustical Laboratories for testing, which resulted in an industry-leading rating of STC 53. A detailed breakdown of the test results can be seen here.

STC stands for Sound Transmission Class, and is used to rate how well interior partitions attenuate sound; a rating of 53 is considered a high grade, and is suitable for commercial applications where sound attenuation is paramount – Conference rooms, sound-controlled environments, quiet spaces, and even recording studios.

The STC 53 rating that the Avalon Tacitus System achieved is one of the highest in the industry, and by far the highest for a standard 1-1/2″ face system with typical 4-7/8″ wall construction.
