I need your advice in deciding whether or not to keep exisitng insulation
my house was built in 1999, I have a basement with Gaurdian Insulation GLF11 R-11 Perforated fiberglass Rolls 48"X78" on the walls, But no stud frames
Now I am planning to finish the basement, Should I put the stud frame and fill any empty space with another kind of insulation OR remove existing insulation and put stud frames and go for R-13 insulation between the studs?
I am kind of confused, I am reading lot of articles from building science consoritum and could not decide on anything
I live in North NJ, I am yet to get the permit.
Appreciate your help in advicing
