installing insulation?

Any vapor barrier always goes toward the living space, with the insulation toward the outside, to allow evaporation of any collected moisture. ( if it ever happens) The packaging always states this, and most times it is written on the product too. You should always check instructions when doing something yourself, to verify what you've been told is correct or not.

This is a major problem with those type stores, they have a bad habit of hiring untrained people and fail to train them.

Many of those people cannot make it "in the field" and are left to give advice to the even less experienced... a very bad situation, as you have found out.

I apologize to all the good employees, but if you are good employees, you also know about the people I am talking about.

the paper on insulation always goes towards the living space or the interior of the building. so yes you have to go back and flip the ones over that are paper up now. sorry that person in orange apron didn't know what they were talkin about.

Learn how to read the instructions printed on the face of the insulation before you start any project you should understand the process and know what you are supposed to be doing. If you want to take it out and reinstall it as it should be done, that's fine. Otherwise, call a qualified professional to do it right the first time.
