Abstract

In this study, fire resistance test according to KS F 2257-8: 2015 was carried out to compare fire resistance for wall consisted of gypsum boards with two types of drywall with gypsum boards which is based to lightweight studs. As a result, it was found that the fire resistance of the wall constructed with 12.5 mm of general gypsum board was 16 minutes higher than that of the wall constructed 9.5 mm in accordance with integrity and was 9 minutes higher than that of the wall(9.5 mm) depending on insulation. If the wall with the gypsum board 12.5 mm is constructed, it can be confirmed that the fire resistance is improved by about 43%.
