Is fire retardent OSB typical in duplex dwellings? I find lots of FRT sheathing (plywood) in older duplex(s). I am pretty sure the blackness I found todayis mold/mildew although I want to be sure it is not charcoaling. Thanks everyone and long live NACHI

I tell clients to check the attic in colder winter weather and call me if there is excess condensation/frost on the sheathing.....then we can work on the causes. |

There are attic moulds that are green or white when active and leave a black stain like in your pics after they die. Active molds of any colour can be wiped off with a finger, so that's a good test. Be careful scaring people when there's just a bit of old stain on the OSB. Call for improvements to ventilation if the soffits are blocked, weatherstrip seal on the hatch, stuff like that.

What makes you think it's "fire-retardant" (resistant) OSB, as opposed to standard OSB?
