'foldcolumn' has both a global and a local value. When you create a new widow, the local value of the option is initialized to the global value. You can use :setlocal to set only the local value without affecting the global value, or :setglobal for the reverse.

You probably created you windows something like this:

:set foldcolumn=0
:new
:set foldcolumn=5
:wincmd p
:new

This will create the new window with foldcolumn of 5, because you used :set, which sets both the global and the local value.

If you use this instead, the new window will have foldcolumn of 0:

:set foldcolumn=0
:new
:setlocal foldcolumn=5
:wincmd p
:new

Also this:

:set foldcolumn=0
:new
:set foldcolumn=5
:setglobal foldcolumn=0
:wincmd p
:new

I'd actually suggest putting a :setglobal in your .vimrc for the preferred default setting, and always using :setlocal to set individual windows.
