## Questions & Answers

**Q: If I want to use it to wrap heat/air duct pipes up in the attic, should the aluminum side be on the inside or outside?**
A: Should be on outside.  The shiny surface has two functions:  If heating season, the shiny surface has less heat radiation into the attic than any other surface color.  When cooling, that shiny surface reflects -reduces the absorption - of heat radiation.

**Q: Want to insulate the kitchen fan exhaust pipe; is this an appropriate product for that use?  If not, what should I use?**
A: This would work using aluminum foil tape for the seams.

**Q: How many sheets?**
A: This is a roll of insulation 12 inches wide -- 15 foot long and 2 inches thick, there may be sheets of material in the 2 inches but I never counted them -- it is just 2 inches total thickness

**Q: Can this be used to wrap an aluminum dryer vent tube to prevent condensation on the outside of the tube during the winter?**
A: I used it to insult my bathroom fan duct running through the attic. I had a problem with condensation dripping down into the bathroom. This fixed the problem.
