I'd say they are wooden blinds because you can see them stacking at the bottom. Silhouettes roll up into the header when you raise them.

Very nice look! With silhouette shades, can you have them drawn from the bottom slightly with slats open or do slats close when you draw the shades up?

Silhouettes only draw up in the closed position. There are other brands out there that you can roll "backwards" about 1/3 up your window. An example would be Comfortex's Shangri-La's.

These look like 2 inch faux wood or wood horizontal blinds. The headrail and end brackets looks exposed on the horizontal blinds. Make sure to cover the headrail with a valance! Usually they come with the blinds, but we also offer them separately.
