Removing title bar just from first page

Hey,

I got START page (first when you come into main adress of site). This START is item of MENU.
On that first site I would like to remove grey bar (which in generally shows name of that section – when you go to Kontakt on that bar will show KONTAKT).
Its not necessary on first page, thats why I want to remove it.

Someone knows how to do it? Ive tried many things and nothing.
