Frost King V73/4T Shrink Film Window KIT, 4-Pack, Clear, Transparent, 42"W x 62"T

It seemed thin, but I purchased an air conditioner, and air comes through the vents. I used this and all drafts are gone, keeping them behind the plastic. A great product indeed, east to install. This is an affordable and effective way to improve window insulation during the winter. The kit includes four clear sheets of shrink film, double-sided tape, and easy-to-follow instructions. It helps reduce drafts and increase warmth by sealing gaps around windows. The application process is simple, using a hairdryer to shrink the film tightly. However, it's a temporary solution, and the film may not be as durable as more permanent insulation options. Overall, it's a cost-effective and quick solution for improving window energy efficiency.

Works great to keep the cold out. Went up easily with one person. This was a concern but worked great. Easily trimmed off excess with scissors. Fits the entire slider doors perfectly. I am pleased and will buy again next year when needed

This works well fire what i use it for... keeping those dang Asian Lady beetles out. I was so focused on that and dry they're real purpose, dealing the windows to kill drafts. I spent less on oil because the heat stayed in. That's a real plus with the price of oil these days. Measure right, cut the sheets, and apply the tape. Easy peezy.

Used for the first time during an extreme cold snap in the winter of ‘25/26. Was a bit skeptical, but it did seem to work well. Could feel the air pressure trying to push in against the sealed film. Kept it up over the summer as well. Not the easiest to put up alone, but not too terrible. Just work slow and steady, otherwise you’ll end up with a stuck together tangle of double-sided tape and plastic film. The look is fine, not perfectly unnoticeable, but pretty inconspicuous. Seals well and keeps out the draft.

Works exactly as described, these tape inside is not as sticky as I wanted but all is funtional

Always my go to to keep the house warmer during the winter

The sheets are à good weight and the product is easy to use

They idea is good, but it has a major problem. The problem is the two-sides strip of tape needed to attach the plastic to the window. It is nearly impossible to peel off the back of the tape in order to attach the plastic. I tried for over an hour to separate the cover of of the adhesive so that I could attach the plastic and apply the heat from my hair blow dryer. It is easy to attach the sticky side of the tape to the window frame, especially once you clean the frame with alcohol. However, it is extremely difficult to peel the other side off. The manufacturer should have thought of a way to make that easy because otherwise it is a waste of time and money. I ended up securing the plastic to the window frame with duct tape.

Keeps cold wind out and helps you reduce on heating bills.

It is easy to apply and helps to reduce the draft and keep warmer the rooms. It saved me money in my hydro bill.

Easy to use, instructions were good, works great

Works well being 1” wide

It was very easy to install. In every other kit i bought, the supplied tape was a pain to use, but in this kit, it was very easy to peel the tape without wrecking it.
