is aluminum foil a compound or element?
That won't happen unless installing the flooring involves compressing the fiberglass 'bat'sInsulation works on 'dead air space'Decrease that by a lot, and even adding more material, (flooring), you might decrease the R valueYou do realize that the floored space you create will be uninsulated right? That might have been what he was trying to tell you.
If the present insulation is even a little above the ceiling joists, you will lose R-ValueIf it is just a little over, you will lose a littleIf it is insulated between AND across the joists, you will lose a lotWhatever you use for flooring will be a poor insulatorIf your joists are 8 and you have 9 of insulation, you will lose more than 11% of your R-Value and gain little by the flooring itselfIf the present insulation is even with, or below the top of the joists, you will gain a minimal amount with the addition of the flooring, which has not compressed the current insulationThe other variable is how much of the attic are you flooringJust making a walkway or a storage pad will have less effect than trying to floor the entire spaceThe other issue is moistureMost attic insulation is open to the attic, with or without a barrier to the living space belowBy capping this, you risk trapping moisture within the insulation layer, especially if you are in a cold climate.
This Site Might Help YouRE: Does putting flooring in the attic over the insulation cause a loss of insulation value? Went to the home improvement store about putting a floor in the attic on top of the insulation and raftersHe said if you do that you lose the insulation value of the insulationThat does not seem right to me, being that you would have the ceiling sheetrock, then the insulation, then the floor.
