Mxclimate One-Piece Full Surround Window AC Insulation Foam Side Panels for Air Conditioner Units, 39'' Width Indoor Window Seal Kit Cover, Winter and Summer

The side panel for air conditioners is a great investment for those who want to keep the hot air outside during the summer months. The foam panel is about 1/4 inch thick and is easy to install and store for future use. It does its job but the double-sided tape that comes with it is not the best quality and may not hold up well. It is recommended to use an Xacto knife for a neater look as the item arrives in a rolled shape which may affect its appearance. However, this product does the work it is intended to do and is worth the money.
