Attic insulation advice


Here's my situation...I just bought my first home about a year ago in Southern Indiana. I went into it knowing it would be a fixer-upper, just not quite this much...but I blame the inspector for that, lol.

I just got up into my attic for the first time a month or two ago and found that I have....wait for it....ZERO insulation (inspector failed to mention that). The ceiling of the room below is drywall on 10" (I believe) center. The roof is corrugated steel over top of what looks like planks and tar/asphalt. The soffits have no insulation, neither does any of the attic. There's currently no vapor barrier between the attic and the drywall ceiling.

Any suggestions on the best way to insulate this attic?

If you have space to get a roll of insualtion, or batts, into the attic between joists, use faced(vapor barrier) 12" insulation. Face goes to the heated side. Otherwise blow in insulation, min 12". Do not cover soffit vents

You could also do a layer of 6" faced insulation, and another layer of unfaced perpendicular to the first. This does a good job of covering any gaps.

Sorry, I made a typo...instead of "The soffits have no insulation, neither does any of the attic." I should have said, "The soffits have no ventilation, neither does any of the attic."

Does this change your advice at all?

I would still insulate, but plan on getting your soffits ventilated, in addition to a ridge vent if that's practical. I don't know if the fact that it's corrugated steel makes a difference in that regard.

If zip starts 477... R-38 in attic. http://www.ornl.gov/cgi-bin/cgiwrap?...le/ins_fact.pl

Do you have any HVAC units or ducts in attic? May want an un-vented attic if local B.D. allows.... http://www.buildingscience.com/docum...r-all-climates

If you have to use f.g batt, don’t get pinked.
