 What is sick building syndrome? 

Sick building syndrome occurs when people suffer from the health disorder due to the contamination of the room air.  Room air contamination caused mainly by the particle matter, and chemical substance.  Particle matters include bed bugs, fungus, bacteria (biological agent), cigarette smoke, house dust, etc.  Chemical substance means volatile organic compound (VOC), which is the cause of the sick house and is attracted a lot of attention right now.  The best known VOC is formaldehyde which is used as an adhesive preservative for building materials, interior decorations, furniture.  VOC is also widely used in daily commodities, such as insecticide, aromatics. These toxic chemical substances cause us health disorder.  Especially, influences to those with allergic diseases, children, patients and elderly are feared. 

Do not use building materials for other purposes.
