Abstract

The requirements for exterior finishing materials have been substantially established recently. After a fire at an apartment building in Uijeongbu City, fire safety requirements for exterior finishing materials used in the buildings that have six and more stories or are taller than 22 meters were specified in 2015, and three and more stories or are taller than 9 meters were specified in 2019. However, the buildings built before that may not accomplish the safety requirements and thus have fire safety problem. This study suggests a method for partially reinforcing the Exterior Insulation Finishing System (EIFS) of buildings to enhance the fire safety. EIFS specimens whose walls on the pilotis were reinforced with a mineral insulation material, were tested in accordance with BS 8414-1. The result showed that fire spread was delayed more than 9 min when compared with an EIFS specimen without reinforcement.
