Had the attic over the second story blown with fiberglass
but it is still 10-12 degrees hotter in the room than the bottom floor.
The walls are well insulated with cellulose so it would appear that the
attic insulation is not working. It is very light -- blows around the
I open the area.
Is there some way to test the insulating value (R factor)?
Any suggestions would be appreciated.
Fundamental law of science, heat rises.
The insulation is probably just fine. You have an air circulation
problem for one thing. But a few degrees of temperature difference
between upstairs and downstairs is to be expected, unless you are
*really* turning over some air volume.
Where is your return duct located for the air handler?
Hint: ceiling fans are cheap, and are great at turning air over,
especially in upstairs situations.
You can't 'idiot proof' anything....every time you try, they just make
