Coolseal is designed for use with portable air conditioners where the exhaust hose is discharged through an awning window. This type of window is hinged at the top and when opened forms a triangular gap down each side of the sash. Coolseal is designed to cover these side gaps which significantly reduces hot air from the outside entering your room. The window's bottom opening is filled by the portable air conditioner's window kit.
