To keep your home energy efficient it is important that all exterior walls are insulated. The same is true for ceilings, especially those on the top floor of your home. If you are renovating an existing home or building a new home insulation is an important step. Plastic backed insulation works best for ceilings.
What size insulation to get…
Ceiling beams are usually 24 inches apart. When you go to purchase your new insulation you will want to get R-19 plastic backed. Ask a sales associate for help if you aren’t sure what you are looking for. Each roll of insulation will be approximately 25 feet long. You will need to purchase several rolls.
What you will need:
- Several rolls of plastic backed insulation
- Tape measure
- Utility knife
- Straight edge
- 2 or 3 boxes of 3/4 inch staples
- Heavy duty stapler
Use a tape measure to find the length of the room you will be installing the insulation in. Measure the room as the beams run. You will only need to take this measurement one time. Write it down so you don’t forget it.
Unwrap and unroll the first roll of insulation. Remember the measurement you have for the length of the ceiling. Use the tape measure to measure the insulation according to that measurement.
Press the straight edge down onto the insulation firmly at the measured point and then run a utility knife along the straight edge to cut the insulation. You may need to run the utility knife along the straight edge a couple of times to get it to cut all the way through the plastic backing of the insulation.
Repeat step 3 until you have enough insulation cut to size to do the entire ceiling. Cutting the insulation before beginning installation saves time and makes the job go much more smoothly.
Fill a heavy duty stapler with 3/4 inch staples. Keep a box of staples in your work belt so that when you run out they are right there. You will use a lot of staples and don’t want to have to get off of the scaffolding several times to refill your stapler.
Set up your scaffolding. It’s a really good idea to have two set up. Have one on one end of the room and have another on the other side of the room. It’s best to have a friend or your spouse help you with the installation process. Have them on the other scaffold so that once you install the insulation on one side of the room they can finish the other side. That way the insulation is not left hanging and you don’t have to move your scaffolding back and forth for each piece.
Place several pieces of insulation up on your scaffold. Do this so you don’t have to get down each time you need a new piece. Unfold the flaps on each side of the insulation. Hold the first piece up to the ceiling and press it in-between the beams. Press the flaps to the beams and inset staples every two inches on each.
Repeat step 7 until the entire ceiling is insulated. Clean up any mess and get ready to install sheet rock!
