Installing an Acoustic Drop Ceiling project

The problem I had to solve was covering up the exposed insulation I put in this music/play room for sound proofing. With the painting complete I decided to install an acoustic ceiling.

My first step was to figure out how much material I need to complete the job. So I measured the room. It turns out to be a 12 x 15 foot space. I took these measurements to my local builders supply store and the attendant and I figured how much perimeter molding ( the L shaped metal piece that attaches to the wall ), main beams (these are the main support for the grids and tiles), cross tees (these pieces are 2' or 4' long and connect with the main beams to make the grid), and hanging wire and other hardware such as screws, etc.

Once I had the space somewhat cleared out and the materials inside the room it was time to get started on the acoustic ceiling installation.

This is the perimeter molding being installed in an inside corner of the room. I didn't have the luxury of a laser, so I measured down from the floor joists and checked my line with a level from time to time making sure the perimeter molding was the same height all the way around the room. Here I've overlapped the corner and used drywall screws to hold the molding in place. I'm down about three inches from the insulation and floor joists to allow room to maneuver the tiles when it comes time to install them.

The bubble in the level window looks good as I continue around the area...I want my first piece to line up with my last piece as I come around the room.

I had an underside of a stairwell to contend with so I had to figure out a way to continue the perimeter molding on a tricky angle such as this. I started by drawing a straight line from one end to the other and measured an exact length.

I decided to cut out the back of a piece of the molding leaving a few tabs to screw into and make a custom piece the will still carry some weight.
