## Questions & Answers

**Q: Probably a dumb question, but desperate. Can this be used over finished interior garage wall to help keep radiant heat from transferring into home?**
A: The two things to ask yourself are:  1) Where is the heat coming from and 2) Is there an air gap between that heat source and the Radiant Barrier?  If you know question 1 and the answer to question 2 is YES, then Radiant Barrier will properly function in minimizing radiant heat transfer.  By applying the radiant barrier directly to your garage wall that is between your garage and the house, this will minimize heat transfer from the garage to the home, but NOT the other way around.

**Q: Is this suitable for emp protection?**
A: Based on all my research, I think it is.  That is what I have used it for.  But there is no way to be sure until an actual EMP attack and see if it worked for  Faraday cage.

**Q: How UV-resistant is the polyethylene scrim--will it withstand long-term direct sunlight in southern US?**
A: I would contact the manufacturer / vendor. I used this product as a heat barrier on the inside of an RV.

**Q: Can this be used for sauna insulation?**
A: Insulate with fiberglass and put this over the fiberglass as radiant barrier for the sauna. Foil on the sauna side.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Really cuts the heat, exceptional product, measure cut and install.
*by T***J on July 17, 2017*

Exceptional product, can't tear it, you have to cut it. 97% heat reflectivity! Installed this everywhere in our RV. Ceiling, walls, floor and it has cut the inside temperature down dramatically. One thin layer does the job. I am ecstatic that I took the chance and purchased this product. It is easy to install: measure, cut and install. Purchase this product if you want your RV to stay cooler, you won't be sorry.

### ⭐⭐⭐⭐⭐ https://lh3.googleusercontent.com/qDwLCsHhlrdkKiwCH_66l13cISYzuTc8qcBLHSkXalVEjw7MoUsyf2dFp7BhogHm9AeMl3MFFHD4MAnCQcAAaHwtxT3y5n
*by H***H on April 10, 2018*

I can make several comments. It is easy to install. You can cut panels and if too short, or a hole (uneven roof) you can just tape over with metallic insulation tape and you don't notice. It reflects light really well and it definitely insulates the attic in winter from drafts and cold. When lights are on, the room warms up.We have not had this on long enough to assess its radiant barrier insulation benefits; that likely can not happen until July here in the far northeast (we still are freezing in NY).What was important to us was insulation against the old attic insulation making it safe to manouver without exposure to that stuff; ease of insertion, and it really does provide insulation against the cold. We have had only 1 60 degree day and the insulation did not get overly warm. I hope to have an opportunity to update this once summer comes.

### ⭐⭐⭐⭐⭐ Great product, cheaper locally.
*by S***S on March 23, 2016*

This is really nice stuff. It's actually a lot cheaper at HD but it's not stocked and delivery is slower so I paid extra to get it quicker from Amazon.It's very tough and thick and does not tear but will cut easily.I would highly recommend getting a $20 pneumatic stapler from Harbor Freight to install. Of course you will need a compressor for this but it's worth it. I used around 2000 staples for a 1200 sq ft attic.After install this really made a difference in my attic heat. Well worth it.
