A bit pricey but works well

Use this this to seal around the sashes where window air conditioners are installed. If you have used a window A/C you know the gap at the top edge of the lower, inside sash. It prevents intrusion of hot outdoor air. I used to buy it a local hardware store for about a buck a piece, but they didn't have enough stock this spring and sold out before I could get there. This is a bit pricey at 10 bucks per 4-pack, but they bailed me out and now I have spares for the future.
