Adding insulation and a plywood ceiling to your bare ceiling is a typical home improvement project for the basement or attic. There are many factors to consider and physical strength is required to install the plywood sheets. If you have a helper the process will go much more smoothly than if you work alone. Without help it will take a weekend or more of your time.
Instructions
1. Measure the length and width of the ceiling and figure out how many boards will evenly fit on the ceiling space. It is important to cut the boards into even lengths and widths so they properly fit on the ceiling.
2. Put on a dust mask and rubber gloves over long sleeved shirt. Install a layer of insulation by pressing the unrolled sheets in between the ceiling joist boards. Cover the entire ceiling this way.
3. Draw a line on each plywood sheet with a pencil and drywall ruler every 16 inches across the width of the boards. This marks the location of your joists and tells you where to place your screws and drill.
4. Hold the plywood boards up to the ceiling joists (have a helper assist you in this step). Drive a 3-inch wood screw into the board and into the ceiling joist using the lines you marked as a guide. Place the screw right on the line each time. Drive in at least three screws, or as many as needed to securely hold the board in place. Continue this process until you have covered the entire ceiling with plywood.
