## Questions & Answers

**Q: How is everyone securing this to their rv windows? we don’t want to use spray adhesive as suggested by a few reviews. thanks.**
A: We used industrial strength Velcro. Lined the edges and bottom of each window just outside the window frame and cut the insulation to match. The industrial strength Velcro adhesive has continued to hold up even with 100+ degree days. This way we can remove it when we want. And it doesn’t look bad - nice and tidy over the windows.

**Q: What is the R Value of the 5mm?**
A: In the description... R-value up to 15.67 ( with one layer), up to 21.10 ( with two layers).

**Q: Good to keep the heat in?  Fig I could use it to cover my window**
A: It should work either way

**Q: Has anyone used this over crawl space vents to keep it warmer during winter?**
A: It would work well, cut 3/8" larger than both dimensions and press fit. I should caution you, unless you are having a problem with freezing pipes, you should never close the vents in the winter, moisture will collect on the underside of the house above the insulation causing mold. Air movement in the un-conditioned space under your house is critical.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 100/10 would recommend for blocking Heat flow from attic
*by A***R on July 29, 2025*

As an energy engineer, I wanted to make sure my home's building envelope was as closed as possible. This product worked really well for that!We stapled a layer on either side of our attic hatch cover and it stopped the flow of hot air from our uninsulated attic space completely.We also used it by stapling it to a piece of hardboard to block off the opening to our crawl space. Temps have been in the high 80s up to the 100s and we needed a quick fix. Worked really well.

### ⭐⭐⭐⭐⭐ VERY EFFECTIVE!!!!
*by A***A on June 10, 2024*

I bought this to insulate my windows & doors. Let me just say that this is a VERY GOOD QUALITY PRODUCT!! I decided to spend the extra money & go with the 5 mm thickness & I'm VERY HAPPY WITH IT!!! The temperature in my house has gone down at least 8°F since Installing the insulation. I am very happy with the overall value.I can say it is very heat resistant because I am also using it to insulate the exhaust from one of my inside Portable AC units & with it on there, you CAN NOT FEEL ANY HEAT COMING FROM THE EXHAUST HOSE.It is pretty easy to manuver to cut to size. It actually has pretty good sound insulation considering it's not the thickest available. I also did not have any issues with using adhesive on it. I really like the material it's made out of.I highly recommend that you spend a little money NOW to SAVE A LOT, LOT, LOT MORE MONEY 💰💰💰 down the road!!!!

### ⭐⭐⭐⭐⭐ Works great!
*by A***S on October 13, 2024*

We moved to Texas this summer and it was so hot that the a/c ran all day. We were paying $500/month to cool our 2-story home. I could tell the heat upstairs was coming through the windows so I started looking for a thin insulation I could Velcro over the windows to help. When I saw the video of another pleased customer who used it to insulate the roof of their metal roof workshop. The video showed them using a heat thermometer gun to measure the temperature and it was 20 degrees cooler on the roof the insulation was on compared to the other side without the insulation. I wanted to give it a try. It was more expensive than some of the other stuff but I didn’t want bubble wrap insulation. So I bought a 100 ft roll and put it on the windows upstairs in a few rooms. I also put thermometers in those rooms and they were 5 degrees cooler than the room I didn’t put it in and I noticed my a/c running less therefore my power bill dropped $100. It paid for itself in the first month. Now with winter coming we will see if it also help to keep the heat in.
