This window sealing kit includes six rolls of 2" x 1/2" x 6.56 ft foam strips and twelve adhesive glue points. It is designed to seal gaps around window air conditioners, portable AC vent setups, sliding windows, door seams, wall cracks, and other indoor openings. The high-density resilient foam blocks unwanted air transfer, keeping cool air inside in summer and warm air retained in winter to cut energy use and enhance indoor comfort. The soft yet durable material rebounds quickly after compression, creating a tight seal that improves cooling performance while also offering windproofing and noise reduction. The flexible foam can be easily trimmed to fit any needed size with basic scissors, making installation straightforward without specialized tools, and works for a range of household and mobile gap sealing as well as cushioning applications.
