Why is dry insulation still hazardous when previously wet ?
Posted: Wed Nov 19, 2008 7:13 pm
10 years ago we buyed a house that had suffered some waterdamage.
We renewed the roof, but didn't pay attention to some relative small spots on our ceiling where water obviously must have leaked through.
Now the communal health inspector orders us to replace all insulation that's infected with microbes.(our ceiling insulation consists of sawdust and shavings)
No test for presence of hazardous microbic excretions have been performed though.
The assumption is primarily based on some stains on the ceiling that have occured 10 years ago wich has been exposed to leakage for the duration of maybe one summer.
He sais if insulation has been exposed to moist for the duration of only one week, it already will have contracted all kind of harmful micro organisms. (I suppose he referes to moulds and their spores)
Might be true, but I honestly can't comprehend how microbes and their excretions can still be actively hazardous in a bone dry environment for over 9 years while beeing sandwiched inbetween tar paper layers.
Could anyone in here please explain how or why the previously described situation might still be hazardous to our respiratory organs ?
And in addition p'haps... how it is possible I'm still around to tell the tale?
