As many of you know, Digital Media is planning to build an audio booth in the room where our old lobby used to be. To access the audio booth, we would like to cut a doorway in the wall that separates digital media from the former lobby (where the tv is mounted). Direct entry to the booth from DM is ideal because it will minimize the noise that enters the booth from the rest of the space. In trying to get started on this, we have found that the wall is definitely not drywall. Does anyone know what that wall is made of? This information will help us immensely in planning our great renovation : )
Thanks!
