Due to (black) water contamination, and ensuing environmental
conditions, my house developed an extensive problem of toxic mold
growth. We finally gutted the place - tore out all the flooring,
interior wall coverings, even the insulation - right down to the stud
walls, to give the mold nothing else to grow on. It goes without
saying that the house has had multiple professional applications of
fungicides and mildewcides, etc., to kill the stuff. We have done
everything possible, to kill the beast, and it seems to finally be
gone. Now I need to install insulation before moving on to restoring
walls, ceilings, etc. Money is a big consideration at this point, as I
ran out of insurance ALE's almost a year ago, and have been paying for
everything from my meagre savings. So, I am now very cost-conscious.
The up-front cost of sprayed on, expanding foams such as Icynene are
more than double that of fiberglass. However, the foam fills all gaps
and cracks, and it claims to be mold inhibiting. Considering the
battle I've had with mold, it might be worth the extra cost. Has
anybody had actual experience with:
1) the insulating effectiveness of foam compared to fiberglass
2) the soundproofing effectiveness of foam (I've been told that
increasing from 3 to 5 inches depth of foam between floors will greatly
dampen sound, transmission. That is a BIG plus, as I have a "music"
loving teenage boy whose band likes to practice at our house!)
3) whether foam really does inhibit the re-growth of mold
4) does today's foam insulation break down like the old stuff, or
remain its integrity?
Thanks very much!
