What frequency is reflected using 1cm thik timber slats?

Hi I was wondering if some knowledgeable acoustics person could answer a very straightforward question. If I have a completely dead room bass trapped to hell with low density fiberglass on all walls, and ceiling, and want to use timber slats with a thickness of 1cm over the 4 walls, what frequencies can I expect to be reflected back into the room? I am sure there is a threshold where frequencies below a certain point are absorbed into the treatment behind the slats. Can anyone help with this?
