초록
The heat transfer characteristics of wood-based flooring boards bonded with natural rubber or cork chips for reduction of floor impact sound were investigated. When the elastic body is bonded to the bottom of the flooring board, the thermal conductivity of the flooring board is reduced, and the decrease in thermal conductivity is greater in the cork having a lower thermal conductivity than natural rubber. In the floor heating environment, the surface temperature of the flooring board bonded with the elastic body is lower than that without the elastic body. Under the same floor heating conditions, the indoor air temperature of the test apparatus is different from the flooring board surface temperature. That is, the temperature difference of the indoor air is greatly reduced than at the flooring board surface. From the results, it is not necessary to recognize about the decrease of the heat transfer performance of the flooring board due to the adhesion of the elastomer.
Abstract
