I use this stuff as a ground cloth under my tent instead of an expensive footprint.

It's lighter, surprisingly durable, water resistant, and you can't beat the price.

On par with a Frost King 4pk on per unit price, except that, for me, it offered a $0.55 account credit on top. In for one pack.

It would do both.

It forms a protective barrier that helps block the transfer of heat or cold, keeping hot air out in the summer and warm air in during the winter.

The OP product people seem to hate the tape it comes with, impossible to peel off. Maybe splurge the $0.55 Roll Eyes (Sarcastic)

So I am looking at the videos on how to apply this, I am little confused. So once you apply this, you cover the entire window for good and no longer would be able to open and close it, is that correct?

The plastic appears to be in front of the window. I have a feeling a child will go and poke it or break ir by playing with it. It seems dangerous for youn ones. Buyer beware.
