Mr Gocze,
I have a question on insulation.I have 9 inches of loose insulation in my attic with no vapor barrierand would like to add more [ such as the type that can be blown in]Do I need a vapor barrier and where ?
Thank you.

Hi Larry,
I would add another six inches minimum of cellulose insulation on top ofwhat is there.It is good to have a vapor barrier. The vapor barrier should be on the roomside of the ceiling.Since a vapor barrier is difficult to retrofit, a tight ceiling is the nextbest thing.The drywall should be sealed and any cracks should be caulked.A vapor barrier paint can be helpful to seal the ceiling also.
