Guest guest Posted July 27, 2002 Report Share Posted July 27, 2002 If walls are cooler than the room, common for basements, the relative humidity (RH) at the wall will be higher than that measured at the warmer middle of the room. So, mold may grow on the walls, if they are dusty. This is more of a problem in basements with some paneling covering the concrete, particularly if there are minor walls cracks through which water can enter the home and remain hidden. With any paneling or drywall, RH at the wall may be 80-90% at the concrete and the back of the wall cover, even with good concrete, though center room RH is far lower. Ceilings do not have this problem, generally being warmer than the mid room temperature, thus lower RH. Ceiling tiles generally only become a problem when water drips on them. If you remain unsure of ceiling tiles, remove them, clean off the dust, and spray lightly with dilute Clorox. Re-install after drying.

And we have addressed this with 4 humidifiers and 4 meters. These were purchased while we lived in an apartment for 6 months. We are keeping the humidity levels below 50% and trying to stay closer to 45%. But we have felt that we need to be extra careful and would like to used suspended ceiling tiles that are not made of a material that mold uses for food. We would like advice/recommendations for the replacement of suspended ceiling panels in the basement of our remediated moldy house. We had standard ceiling panels that contained cellulose before remediation. They were in place since the house was built 8 years ago. We did not find any evidence of mold on them. However, we threw them all away anyway, just to be safe. We really don't want to use anything that could be eaten by mold or harbor mold spores (or worse yet, contain recycled materials that had mold in them). We are looking for ideas if anyone has knowledge or experience with this issue.
