Supplies and Materials

Here are the supplies and materials you will need for this project:

1. Measuring tape
2. Straightedge or ruler
3. Pencil or marker
4. Protective gloves
5. (2) sheets of 1/2-inch thick foam board insulation
6. (1) roll of aluminum foil tape
7. Box cutter or utility knife
8. Safety goggles

Step-by-Step Guide

Follow these steps to make your own attic ventilation baffles:

1. Measure the distance between the top plate of the exterior wall and the roof sheathing at the location where the ventilation baffle will be installed. This measurement will be the length of the ventilation baffle.
2. For the width, measure the distance from the soffit vent to the roof vent or ridge
3. Cut two pieces of foam board insulation to the measured length and width with a box cutter or utility knife.
4. Next, determine the height of the ventilation baffle by measuring the distance between the bottom of the roof sheathing and the top plate of the exterior wall.
5. Mark the height of the ventilation baffle on one of the foam boards.
6. Using a straightedge or ruler and a box cutter, score the foam board along the marked line. You may need to go over it a few times to create a clean cut. Be sure to wear protective gloves and safety goggles.
7. Repeat step 6 for the other foam board, ensuring that the cuts align perfectly with the first board.
8. Once both foam boards are cut to size, place them parallel to each other with the scored sides facing each other.
9. Using aluminum foil tape, seal the two foam boards together on both sides and on the bottom edge. Ensure that there are no gaps or holes.
10. Once fully sealed, insert the ventilation baffle into the space between the roof sheathing and top plate of the exterior wall. Be sure that it is a snug fit and secure with additional aluminum foil tape if needed.
