Draft Prevention: Features a sandwich structure with PU foam wrapped in nylon, providing insulation like an air layer. Fills gaps and significantly reduces drafts. Eliminates rattling noises in strong winds, as well as light, pollen, and insect intrusion. Energy Saving: An item that can improve the effectiveness of air conditioning in summer and heating in winter. Prevents the escape of cooled or heated air (by preventing leaks from window and door gaps), improving air conditioner efficiency and reducing power consumption. Soundproofing & Condensation Prevention: The cushioning and thickness provide a cross-section structure similar to double-pane glass, offering soundproofing. Applying it to the outside can prevent cat scratches. The surface is made of thin nylon with fine irregularities, providing good product slip. Also helps prevent condensation caused by temperature differences between the inside and outside of the room. Easy Cleaning After Application: Products with a fuzzy texture can be difficult to remove small insects from, and are troublesome to handle when wet because they don't dry easily. The cushioning material in this product is coated, preventing the entry of small insects and water, and is easy to wipe clean even when wet. Privacy: Opaque, blocking views from gaps and protecting room privacy. Includes a Japanese instruction manual. Product size: 30mm x 5m. Can prevent drafts from both the inside and outside.
