Installing the full panels is as easy as just slipping them into the grid (see part 9) from below and dropping them into place. Be sure you wear clean gloves or have clean hands so you don't soil the white tiles.
The border panels will need to be cut to size. Usually, the larger, 24″x48″ flat panels require only a straight cut with a sharp knife or saw to fit between the grids and the wall molding.
For the tegular, 24″x24″ panels (tegular means two levels, or that the face of the tile is lower than the grid level), you will have to cut in a flange on the freshly-cut edge so it will fit the grid.
To do this, measure the size of the opening plus the flange. Place this panel in position in the grid. Rest the cut side without the bevel and flange on the wall molding. Draw a pencil line where the wall molding meets the border panel, making sure the opposite end of the panel is centered in the grid.
Remove the panel and lay it face up on a flat surface. Cut along the pencil line in such a manner that your utility knife (use a sharp one) only penetrates half the thickness of the panel. Finally, using your utility knife, laying it flat on the table, cut halfway through from the other side to meet up with your original cut. Now, install this tile in your grid.
Once your tiles are installed, that's it: your suspended ceiling is done. There are plenty of other features you can install, scenarios you might encounter, and maintenance tasks you'll have to undertake in regard to your suspended tile ceiling, though. Continue to the 11th and final part of this series to learn how to handle them.
