Performance Evaluation of Dry Double Floor-System Using Recycled Materials

Abstract

Typical wet floor systems applied in most Korean housing units require refurbishing as they have a shorter lifespan than buildings. Construction waste, yielded by such refurbishing, can cause social problems such as environmental issues. In order to reduce such problems, a dry double floor system had been developed with the use of recycled materials. In this study, we evaluated performances of a developed double floor system, such as impact sound and radiant heat. As a result, floor impact sound was around 40 dB for light-weight types and around 48 dB for heavy-weight types, respectively. Moreover, radiant heat generated from the double floor system increased by approximately 28% compared with one of the existing Korean wet-floor heater type systems. Eventually, other evaluations were performed for items including environmental harm as required by the Korean building code, and the results showed that the developed dry floor system met all applicable Korean standards.
