Review: Foil could be better - Bought a different brand a year ago but this one recently. It’s not as good in quality as my first one but it works. I find the foiling to be thinner and therefore not smooth. Lots of wrinkles etc. it also has excess foiling on the end which is not needed and I have to tuck it under. Next time I’ll buy the other brand again.
Review: Good addition, minimal effort. - I am using this for a bathroom remodel. The original fiberglass wall insulation was insufficient on this cold, northwest corner of the house, but this will be a huge improvement. It is easy to work with and cut, and the minimal thickness adds a decent R-value AND radiant factor.

## Questions & Answers

**Q: Can this be glued up?   Thanks**
A: Yes. Before the insulation is glued be certain that the glued area is clean and dry. We used this insulation glued to the fiberglass top of a cargo van to reduce heat transfer. The inside of the cargo area stays some what cooler in the summer and slightly warmer in the winter keeping the cargo at better temperatures then outside.

**Q: Is it durable to attach/reattach to an RV to block the hot texas sun?**
A: I cut to fit my RV windows wrapped edges of this with gorilla tape super glued velcro on it and other side of velcro in my window groove all the way around so its sealed. Keeps heat out keeps heat in the winter windows don't freeze up. Time consuming yes but what else was I gonna do with my time

**Q: Is this product rodent resistant?**
A: No matter what anyone  says.....  nothing is rodent resist. 
Resistance is futile

**Q: May I use this on RV windows?**
A: This is best type of insulation for RV windows. It will reflect 97% of radiant heat, plus have a great resistance to conductive flow of heat. AD-5 reflective insulation will stop both Conductive and Radiant flow of heat, also good sound barrier.
