    Note to Installers

    Sound Silencer™ is a thermal-molded acoustical sound panel. Although tough to see, one side of the sound suppressor panel will have injection and mold release marks these are circular marks that range in size and indent depth. These marks denote the back side of the cleanable acoustical sound panel so panels should be installed with these marks facing the wall or ceiling for best possible aesthetical outcome.
