Continue to work up the rafter bay until you reach the roof peak. Overlap each baffle with the next. If the baffles extend below the soffit vents, you can seal them. Spray foam is the best choice. Foam blocking may also be required. You can use this to fill in larger spaces. Caulk any seams between the overlapping baffles. Insulation can be added to your baffles.
Baffles can be used to stop the flow of gas, fluid, or air. They are often used in conjunction attic vents. Attic Air claims that baffles allow for proper airflow and prevent insulation from clogging vents. They can be made from rigid waterproof foam, plastic, or cardboard and are available in different lengths. They are installed between the rafters of your attic ceiling.
