Gluing to the wall: The felt panels are directly glued onto the wall. This is the most affordable installation option. If 18-mm felt panels are used, a Chameleon whiteboard can be installed at the same depth as the rest of the wall. It is not possible to combine glued 9-mm felt panels with Chameleon whiteboards.
Chameleon magnetic mounting system: the felt panel is equipped with a 0.4-mm steel rear panel. Magnet strips are installed onto the wall, and these allow the panel to click in place. This gives the 9mm felt panel the exact same depth as a Chameleon whiteboard panel.
