발코니 확장(擴張) 허용(許容)에 따른 외부창호(外部窓戶) 성능(性能) 개선(改善)에 대한 연구(硏究)

The revised legislation is introduced that the extension of the balcony area for the apartment houses is allowed. In the past the tenants had to install them illegally by themselves when they wanted to extend their balcony. We have reviewed the standard of the balcony's windows to be set up for them because the contractors can construct the exterior windows. At present, the detailed capacity standard for them is not established Of course some items of them are classified within five capacities among the KS standards. But the standard of the extensional balcony windows are not defined. Therefore this study is aimed at setting up the criteria of the noise, insulation and leak for the window system in expanding the balcony area and adopting it into window's works.
