The special waterproof TU fabric undergoes thermal insulation treatment, efficiently reflecting sunlight for rapid cooling, delivering energy savings and cost efficiency • Adjustable Universal Size: Air conditioner window kit dimensions (width) 10 x 40-64 inches (length), with adjustable length range 40-64 inches.
