Add on the Easy Up track and clip system, which installs surface mount ceiling tiles or planks directly to joists or an existing ceiling, maximizing ceiling height in a room. Tracks and clips are both needed for a complete installation. If your existing ceiling is drywall or plaster, a second option would be to use adhesive to apply tiles directly to your existing ceiling. A package of ceiling tiles covers 40 square feet with 40 pieces per carton. A box of tracks contains 20 tracks and covers about 100 square feet, and a box of clips contains 135 clips and covers approximately 100 square feet.
