Our trim is being done, and we've been told that the widest windowsill we can have is 2 5/8". Where we still have older windows in another part of the house, they are 2 3/4".
Our contractor said that newer Andersen windows are meant to be picture framed, which for some reason makes it impossible to have wider sills.
Does this sound right? I don't know enough to assess this myself.
My preference would be to have slightly more than the 2 3/4", so getting less than that is a bummer.
