Yes! Save your old acoustic tiles! In many cases, Brutal tiles will be installed where there are already existing acoustic tiles. In some cases, the acoustic tiles can be placed diagonally above the Brutal tiles or sitting directly on our tiles. This also avoids discarding a large volume of mineral tiles. Any tile that has less than 1.4” protruding above the grid plane will allow this. This includes Bilbao, Brasilia, Blox. All of the other designs would have to be only pointing downwards to work, or the ones pointing upwards would not have the mineral tiles above. This should still give some acoustic properties. Installation is tricky as the access is necessary though the next opening to hold the acoustic panel up while the Brutal tile is placed. The other tile options that point upwards require a minimum of 2 1/4” clearance above the grid plane, so extra clearance must be created, or they sit on the diagonally placed mineral tiles if 5/8” thick or greater.
