These are two self-adhesive foam panels that seal the gap between a window air conditioner and the window frame. The urethane foam blocks outside air, noise and vibration better than the thin plastic wings that come in most AC boxes. They suit anyone with a window unit whose original side panels are cracked, missing or drafty. Compared with generic accordion panels, the foam is thicker and quieter but less rigid and not a universal fit, so measure your opening first.
