It fits all types of sliding devices (horizontal or vertical) and is compatible with portable air conditioners or air dryers. Prevent cooling air leakage: Made with special TU fabric for insulation and treated with a heat insulating bleaching process, our seal effectively blocks the loss of cold air while reflecting sunlight and heat outdoors. This helps cool the room quickly, save energy and reduce costs. Complete sealing: The seal ensures a tight and gap installation thanks to its material and extended fixed sticker. By preventing cold air from escaping and preventing flies from entering, it provides protection. Improved details: The climate seal has precise cutting and milling areas, allowing for adjustment without distortion. In addition, the texture treatment near the outlet prevents the tape from falling off after inserting the air hose, avoiding any gaps that may occur.
