I have perused a couple of threads, but they seem to be in the reverse
(rolled insulation is already in the attic).
I have a house in northern Michigan built in 1979. It has blown
insulation in the attic. About a year after we moved in, we discovered
that one of the bathrooms was venting directly into the attic. I have
that situation rectified now, and the damage to the wood repaired.
However, I was told that the insulation may have become sodden too.
What I would like to do is go to Home Despot or similar store and buy
some rolled insulation and roll it on top of the blown stuff. Is this
Also, When we moved in there was about 2 inch of styrafoam on the
basement walls. I was told by the building inspector I had to tear
that down. I did. But I have been told since by a few people he was
full of it and that it is also hurting my heating. The house is hot
water heat and the boiler is down there. It never seems too cold, but
still. (I have all the hot water pipes down there insulated). Should I
put the stuff back up?
