1. Adjustable size: Choose between two sizes, about 300 cm and about 400 cm to adjust the length of our climate seal according to your needs. This seal fits all types of sliding windows (horizontal or vertical) and is compatible with portable air conditioners or air dryers. 2. Prevent air leakage: Made with special TU fabric and treated with a heatinsulating bleaching process, our seal effectively blocks the loss of cold air while reflecting sunlight and heat outside. It helps reduce energy waste and high costs as the room temperature cools down quickly. 3. Complete sealing: Our climate seal ensures a tight and gap installation thanks to its material and the extended fixed sticker. It not only prevents cold air from escaping, but also keeps flies and other pests away and provides excellent protection. 4. Improved details: With precise cutting and milling areas, our climate seal allows for easy adjustment without distortion. The texture treatment near the outlet ensures a seamless, gap seal.
