Acoustic slat wall panel Installation Preparation - Before you start installing the slatted wall, you need to calculate the number of panels you will need. The wall on which you plan to install the slats should be a flat, smooth, dry, and dust-free surface. PLEASE NOTE - Clean the wall and check its level before installation. The housings of the sockets and contacts should be removed and the lighting holes drilled.By using black screws for the black backing option or silver or grey screws for the grey backing option, the panels can be screwed directly into the wall through the sound absorbing felt. We recommend using at least 9 screws per panel, spaced 200mm apart in width and 800mm down the length of the panel. If installing on a ceiling, make sure to screw them into the ceiling joists. For example, if entering drywall, make sure you use the correct fixtures.
