Many researches on the typology of 'Maru'(Wooden deck) in Korean traditional houses have mainly focused on the high-class houses in the central region of Korea. They were mainly concerned on defining Maru's typology by social status of the owner, based on the researches regarding its physical and spatial properties. Maru in the high-class traditional houses has been served as an essential architectural feature showing the social status of owners as well as adapting in the region of humid and hot summer. This research investigated the typology of Maru's placement in traditional single houses of four Kan in Chonnam province, which shows many differences in its placement according to the regions. Research results show that the typology of Maru's placement and openness is different with the location of houses within the region. This difference affects on the circulation of movement, which eventually affects on the pattern of space use. The difference is also very likely to be affected by the natural environment of geography and climate of the region.

Experimental results show that the maximum temperature of the floorboard surface is 1/2 level compared to the hot water temperature of 80℃, which is circulated by hot water heating. And the part above 10mm above the surface of the floorboard was low as 1/3 level. Therefore, in order to improve the heating efficiency of the room where the flooring is applied to the hot water heating, the thermal conductivity of the flooring material should be improved as well.

As a result to check basic physical characteristics of plyood and fabric board, both of them satisfied the criteria of KS F 3126 but hardened fabric board only showed changes in the absorption width expansion rate. This may imply that continuous expansion and swelling can occur if hardened fabric board is exposed to moisture for longtime, and it should be considered when selecting a product and mainteaning it.

As a result of abrasion resistance test of decoration wood-based flooring board laminated with PVC on plywood, compared to the flooring board laminated with general HPL surface decoration materials, it was available to secure far higher abrasion resistance. It seems to contribute to secure initial durability and maintenance of decoration wood-based flooring board as an important means, and it might be available for saving repair and maintenance costs due to flooring board issues.
