During the cold weather months windows become a prime spot for energy loss. Duck Brand Rolled Window Kits create an added barrier between the outdoor air and the inside of your home helping block drafts and air leaks that lead to high heating costs. Our window kit film comes in an easy-to-use roll of shrink film which means no measuring needed — simply cut the extra film off once applied. Plus the kit uses crystal clear shrink film for good visibility and is easy to install and remove. For best results use on clean and dry surfaces such as painted or finished wood aluminum or vinyl.
