Review: Great insulator - I just completely covered my bedroom window with this in the winter since I only ever just sleep in there anyway. Kept my room much warmer than without it. I couldn't really use the cling film since there's no trim on my window.
Review: Thicker than Home Improvement store and a little less cost-wize - But if it matters to you I did not come in a roll like the pic, it was folded up and folded up _a lot_ so pretty creased

### ⭐⭐⭐⭐⭐ Great insulator
*by R***N on September 12, 2024*

I just completely covered my bedroom window with this in the winter since I only ever just sleep in there anyway. Kept my room much warmer than without it. I couldn't really use the cling film since there's no trim on my window.

### ⭐⭐⭐⭐⭐ Thicker than Home Improvement store and a little less cost-wize
*by G***N on November 18, 2023*

But if it matters to you I did not come in a roll like the pic, it was folded up and folded up _a lot_ so pretty creased

### ⭐⭐⭐⭐ Good insulation, but can be hard to install
*by E***E on December 31, 2025*

I used this to temporarily cover up an in-wall AC unit. I found it difficult to secure to the drywall using heavy-duty staples and nails, because the staples would cut right through the material entirely. It’s not very strong, rips easily. As far as insulating goes it does seem to be performing well - it definitely keeps heat in.
