Wooden Houses Jalousie Windows
Earthquake resistant wooden houses in tropical region often use jalousie windows (usually located above or beside the glass windows) as ventilation system for the cooling of rooms. Generally glass louvred jalousie windows are installed at the front walls near the verandah or at the living room where house owners receive their guests. The louvre windows brighten the indoor rooms because they allow not only the fresh air to enter the houses but also the sunlight. To filter the dust from the street from flying into the rooms, house owners usually install transparent curtain sheets or drapes behind the glass louvred windows. The curtain also improves the privacy of the house owner because people cannot easily see the interior of the house except at nights when the lamps are on. Hardwood jalousie windows can usually be seen in the walls of bedrooms. The combination of jalousie hardwood ventilation holes with glass louvred windows is the most common type of ventilation system in tropical houses. Because wooden houses use timber for the frames, walls and windows, they have to be specially treated. Wooden structures need to be covered with paints or varnished to protect them from water vapor that can cause them to rot.
