Jalousie window while keeping out water was deemed unsatisfactory by the study's authors. Jalousie windows also have several other drawbacks. Traditional style jalousie windows offer poor overall resistance to water penetration and drafts and are difficult to positively secure, as their slats are easily and silently removed. In addition to the inability to keep out water, they do not provide a secure barrier to keep air conditioned air inside. Also, the metal parts which make up the windows moving mechanism are prone to corrosion in humid environments, leading to damage such as broken or missing cranks. Jalousie windows are objects of scorn
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. In the library at Venice, Sansovino varied the design by substituting columns for the two inner pilasters. To describe its origin as being either Palladian or Venetian is not accurate; the motif was first used by Donato Bramante and later mentioned by Sebastiano Serlio (1475–1554) in his seven-volume architectural book
