AIR CONDITIONER SIDE INSULATING PANELS let you keep your big, heavy window unit in place all year long! Sponge-foam insulation installs easily over existing side panels of air conditioner unit. Keeps cold air out in winter, hot air and bugs out in summer. Also reduces air conditioner noise and aids efficiency. Set of two 18" x 8-3/4" panels, each with self-stick side rails.
I had a little bit of difficulty cutting the panels to fit my air conditioner, but I'm glad I bought them. They are helpful in keeping the stink bugs from getting into my house.

We have them on all of our air conditioners and they have helped cut our electric bill. They also blocked out the dirt that also sneeks in. I love them!!
