Louvres have been an important part of architecture since the Dark Ages. People used louvre systems in the construction of their homes, mostly to protect themselves from the sun. Aluminium louvre are shutters that have horizontal slats that can be put into different angles to shade from the sun. In the present day we mainly place aluminium louvres for decorative purposes and architectural beauty. Louvres we’re often made, and sometimes are still made from wood. Modern louvre systems are built with aluminium. Occasionally louvres are also made of glass or aluminum. Louvre systems are also used in front doors, closets and ceilings. The use of louvres inside the home is often shading, ventilation or just decoration.
