<DIV>Asked this once before but didn't get any answers, so I'll try
again...</DIV>
<DIV>Had spray urethane insulation installed in the cathederal ceiling of a
small house being renovated (upstate NY). The rafters were only 2x6 and
the installers sprayed in 4", claiming that anything more wouldn't be of
benefit. So, there will be about 1.5" of space left between the urethane
and the ceiling. I'm wondering if it is worth filling that space with
insulation (fiberglas or rockwool) or is that possibly asking for moisture
problems? In fact the house is pretty tight and pretty easy to heat, but
I'm about to install the ceiling paneling and wonder if I might regret not
filling all the space with insulation later...</DIV>
<DIV>Thanks<BR></DIV></SPAN>
