What's a appropriate opening to embezzle stale cement...
Answers:    If you don't plan to use the attic, blown in cellulose have best r-rating per inch and is also the cheapest. Make sure to put in "proper vents" surrounded by each stud cavity, otherwise you could closing stages up with rime dams within the winter.
1300 sq ft will run you about $300 beside free blower rental, a little more if you budge deeper than 12".
