Frost King V73/9H Indoor Shrink Window Kit provides an easy, budget-friendly way to seal windows and cut drafts in winter. Each clear film sheet is simple to install and can help save on heating bills, though it needs to be removed for summer and re-applied yearly. A practical pick for those seeking a temporary solution to improve comfort during colder months.
Reality Check
Frost King V73/9H Indoor Shrink Window Kit is a clear plastic film designed to improve window insulation during colder months. Sold as a 9-pack, each kit covers windows up to 42 by 62 inches. The kit helps reduce drafts and can lower heating costs by adding an extra barrier over old or leaky windows. It’s commonly chosen for its affordability and the straightforward installation process that doesn’t require special tools.
The reality is, this kit works best as a temporary, seasonal fix. Its main downside is that it must be removed every summer, since direct sunlight and regular window use can cause the tape to fail or the seal to weaken over time. There’s also no UV protection, and the window must be re-sealed each winter, which adds a bit of annual hassle. If you’re after a quick, inexpensive insulation boost and don’t mind the yearly routine, this kit is an efficient option.
Best For:
– Renters or homeowners looking for temporary, budget-friendly winter insulation
Not Recommended For:
– Anyone seeking a permanent or year-round window sealing solution
Key Features

- If you want to open your windows in the warmer months, you’ll need to take it off. Otherwise, sunlight and normal stress can also make the tape fail eventually. For a good seal, it’s probably best to re-apply them every year.
