Jalousie window for many Floridians, as the windows are unable to keep out human and insect home invaders. Modern manufacturers have improved their designs of jalousie windows to address these problems.

Palladian architecture Serlian, or Venetian window features largely in Palladio's work and is almost a trademark of his early career. It consists of a central light with semicircular arch over, carried on an impost consisting of a small entablature, under which, and enclosing two other lights, one on each side, are pilasters.
