In a bahay na bato, there are window shutters composed of louvre windows called the Persiana. These shutters are made of overlapping horizontal slats on window panels made of wood. The design objective of these louvre windows is that they let air come in to make the house cooler but deflect the sun’s rays, shielding the interior.
Later on, it evolved into what we now call the Venetian Blinds but these blinds used to be hinge window shutters and were a very popular element of the house in the Spanish-Filipino Era especially during hot summer days.
There are also free-standing persianas called biombos. The biombos was used to divide the dining room and the volada.
