I have been surfing the web looking for info

on what the R factor in the walls of a mobile home should be...and have come up with nothing.

My home is a 1973 single-wide and I am sure the stuff in the walls now is probably original.

I want to replace it, but not sure what R factor I should use. I don't want to use one then say, Oh, I should have used this...

I like to avoid situatons like that.

I live in Florida...

Can anyone help?
