Sorry 24x29 is the measurement, a little off. Thanks for the recommendation on blowing in some more, I may blow in fiberglass just to keep it all the same.
So I have a *edit (24x29) attached 3 car garage (11 foot celing), 1 shared wall with the house. It is a new construction house with r8 garage doors, I did the attic with r30 batts and drilled and filled the walls with celulous. I have a nest thermostat installed and set at 50 degrees Fahrenheit...
