Help Solve family debate....???

Question

I asked this question a few days ago. I got a lot of people saying both...so I'm not sure which is right yet..

Someone in my family had installation put under his house. It's the type of installation that's pink fiber glass on one side and paper on the other. The people who did it put the paper side up, towards the floor and pink side down. So when you look under the house you can see the pink. Some family members say it's done right, and some say it's done wrong (upside down) WHICH IS THE RIGHT WAY!!!!! If you have any websites that can back it up post a link please, if not just tell me which way you think is right! THANK YOU!!!!

Answer 1

I am a contractor.  The insulation backing paper always faces out.  When looking under the house, you should see the backing, not the pink.  the pink should be resting against the wood of the house.
