Step 5 Apply Weatherstrip

Apply self-adhesive weatherstrip along each side edge and the top edge, which will create an airtight seal between the baffle and the door trim. I have left the bottom edge with no weatherstrip. In my house, the bottom edge will "seal" against the carpet. If you are planning on mounting this in a doorway over hardwood floor, you may need to add weatherstrip to the very bottom or even rest the baffle on a rolled up towel on the floor.

The weatherstrip I used was the widest and thickest available at the hardware store - 1.25" wide by 7/16" thick.
