Attic today had three inches of blown-in insulation without a vapor barrier.

Then someone added six inches of fiberglass rolls with a foil faced barrier facing the unheated area.

Another six inches of rolled fiberglass was then laid over that with the kraft faced vapor barrier facing the foil faced barrier.

This is an investment property, an apartment building for students at a local university.

Is it really worth having all the insulation removed, a proper vapor barrier installed and then putting the insulation in correctly (with one of the layers having the vapor barrier removed)?
