How to Use Foam Board on a Ceiling

Foam board is a type of insulation that is used to help conserve energy in a house. You can install it anywhere and it is generally found in between the studs in the wall. Foam board is a good insulator and, depending on the thickness, it can have a high R-value. You can also install it in a ceiling for added insulation anywhere in the house. Installing foam board in a ceiling is similar to installing it anywhere else; any homeowner can accomplish this task.

Instructions

    • 1

      Measure the ceiling of the room where the installation will take place to determine the total square footage. Multiply the width by the length to get the square footage.

    • 2

      Lay the first sheet of foam board running perpendicular along the ceiling. Insert wood screws through the board and into the studs in the ceiling. Move down to the next stud and insert another screw. Continue all the way around the entire foam board to secure it to the studs.

    • 3

      Place a 1x3 furring strip vertically about two feet long directly in the center of the board and screw it into the studs to further secure the board in place. Add two more furring strips in the same manner on either side of the center one and equally spaced. Line up the second piece and install it in the same manner. Continue down the first row until reaching the end.

      Cut the end piece to size with a utility knife to fit in place. Mark where the cut will need to be made and line up a T-square along the line. Follow the T-square with a utility knife and score the piece. Snap it and cut the other side to break it in two and install it in the same manner.

      Install the second row just like the previous one was installed and continue with the rest of the rows in the same manner. Inspect the area to make sure no screws are sticking up.
