Abstract
The insulation performance of the insulation currently used in building structures is reflected only during design based on initial performance and the reduction in heat insulation performance due to the degradation of long-term durability is not reflected. This study reviewed the degradation of heat insulation performance due to the durability degradation of insulating materials through the accelerated durability test. The study findings showed that the foamed polystyrene insulation bead method did not show performance degradation due to aging in the standard environmental condition and laboratory accelerated test condition but the performance is degraded in the freeze-thaw test condition. On the other hand, in the case of the extrusion method, the degradation of the heat insulation performance was less in the freeze-thaw test condition, but the rapid performance degradation was caused by the release of the internal gas at the beginning of aging. In addition, the hard polyurethane foam insulation showed better initial insulation performance than other insulation materials, but the performance was found to be degraded somewhat under laboratory accelerated test conditions and freeze-thaw test conditions.
