Development of Dry Double Floor System and New Materials Used in Apartment Buildings

Abstract:

To the flooring system of apartment buildings, resilient materials are used for reducing floor impact sound. Mainly used resilient materials are EPS or EVA. We developed cellulose resilient material and sound absorber recycled waste papers which are eco-friendly materials and evaluated performances of above materials. In addition, we developed dry double floor system which can replace the general flooring system construction in Korea. Floor impact insulation performance of developed flooring system was compared with the existing one and analyzed. Floor impact insulation performance of dry double flooring system was lower than wet type flooring system. Cellulose absorbers showed NRC 0.37, 0.53 of insulation performance, and in case of applying floor resilient material, it showed a somewhat reduced performance comparing to the existing flooring system.
