*Note to all Installers
Sound Silencer™ PEPP is a thermal molded product and although tough to see one side of the 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 panel so panels should be installed with these marks facing the wall or ceiling for best possible aesthetical outcome.
