Foam insulation — venting before covering?
in a previses question i asked about timing of batts installions
in flash and batt
respondes were very helpful
but still have concerns manf. web sites say wait 24 hours
depending on condition and amounts of foam
i hade read an artical in JLC a while back about problems with foam
were it was stated if you can smell it its still off gasing
most jobs where were going to install batts after foam contracter has finished
seem to have oders well past 2 or 3 days
as so ive read in manf. spec. that if existing attic is being sprayed
all existing insultion has to be removed as not to trap fumes
are these things a problem of foam or the installon????
