In Terminator you can right click and then choose "Preferences" (Or settings? I have a german version).
When you add a new profile (left buttom "add") terminatior will add your current settings.
Give it a name and close the preferences window.
Now in ~/.config/terminator/config your new layout is added.
You can now start terminater with:
terminator -l yourLayout
If you want terminator allways to start with your layout, have a look at that file (~/.config/terminator/config). Should be easy to copy your settings to the [default] section.
