Thank you, thank you Buffalobill.

That's just what I needed, That low density, slow drying, foam.... The
regular foam would blow my drywall off...

Now all I need is to find out if I do put it in MY walls... would it
sink all the way down to the unit downstairs? Typically would there be a
stud? / barrier? in the exterior walls? to catch the foam and keep it in
my walls at my level....

Thanks again BB....

We already answered that. No it won't, and there are firestops in your
walls.

I hought some old 100yr construction did not have fire stops, is that
so.
