Blow in cellulose insulation?

[the_poochies]

I had it blown in between the walls of my 112 year-old victorian house. The contractor drilled a 2" hole in my interior walls between the studs, blew in the cellulose and then patched the hole back up.

The work wasn't cheap....IIRC, it was $1000 for 2 rooms.

I noticed a slight savings in my insanely expensive heating bill, but what I noticed the most was that I no longer heard noise from the busy street outside my bedroom or living room.
