This portable air conditioner window sealing fabric is the essential accessory to optimize the performance of your cooling unit.

Made of high-quality waterproof polyester fabric, it is UV-resistant, withstands temperature variations, and will not degrade over time. It features a double nylon zipper with a sturdy, smooth-gliding alloy slider, as well as included cable ties to secure the drain hose and eliminate any gaps around the duct. Three sizes are available to fit all window perimeters: 3m model (220g, 7m adhesive hook and loop fastener) for perimeters ≤ 300cm, 4m model (280g, 9m hook and loop fastener) for perimeters ≤ 400cm, and 5m model (580g, 11m hook and loop fastener) for perimeters ≤ 500cm. It is lightweight, compact, and easy to store out of season. Installation requires no tools or drilling and is completed in 6 simple steps. Start by cleaning and drying the window frame, stick the provided adhesive hook and loop fastener all around the edge, attach the fabric to the adhesive strip, insert the drain tube into the zipper slot, close the zipper completely, and then tighten the tube with the fastening tie for maximum airtightness. Reusable every summer, this window cover is suitable for most sliding and casement windows in houses, apartments, and offices. Its careful construction with tight seams ensures high resistance to pulling, and you can easily cut the fabric to fit smaller windows, for refreshing and economical comfort all summer long.
