Plantation shutters? I have those on my windows. I like them and they hold up well, plus you never have to do anything to them except dust. :) They also look nice with fabric treatments, if you choose.
Right.. and you don't have to cover the whole window.. just so far and let the light in with the rest. I don't know if I can do anything other than the verticals in the sliders tho. Will see what else they have.
