This window air conditioner side insulation panel set is designed to help seal the gap between your air conditioning unit and the window frame. It includes two 17 in x 10 in EVA foam boards and one 39 in x 2 in EVA sealing strip, making it suitable for replacing a damaged original panel or serving as a substitute.
The panels work like a window seal to help block dust, pollen, insects, heat and airflow. The foam material also helps reduce noise and vibration, supporting a more comfortable indoor environment. For summer use, it helps keep hot air outside, and in winter it helps block cold air indoors, which may help reduce heating and cooling costs.
These air conditioner side insulating panels are suitable for most window units, including 5000-22000 BTU models. The simple installation design makes them practical for everyday home use when you want a cleaner, better-sealed window AC setup.
