LINEAR EXPANSION OF SIDING MATERIALS CAUSED BY DIFFERENCE OF WALL COMPOSITION IN EXTERNAL INSULATION BUILDING

Abstract

In recent years, external insulation building is chiefly constructured to the cold district. But it is easy to be deteriorated variously about siding materials. One of the main causes is thought that temperature change of siding materials by being exposed to the sun. State of dry and wet of siding materials changes by the season and weather is also the main cause. This research clarified that relation between wall composition and expansion and shrinkage of the siding materials in external insulation building.
