Safe against Fire, ‘Age of Tall Wood Mass Timber’ Begins
The two-hour fire resistive performance of a wood frame construction (WFC) was proven for the first time in South Korea. The National Institute of Forest Science (NIFoS), formerly known as KFRI, tested five different main structural members of tall wood mass timber such as glued laminated timber columns and beams and Cross Laminated Timber (CLT) floor and wall materials in the fire certificate testing performed at the Korea Institute of Civil Engineering and Building Technology (KICT). The test materials satisfied the two-hour fire resistive performance.
According to the Building Act of Korea, 5 to 12-storey buildings must satisfy at least two-hour fire resistive performance for its major structural components, such as bearing walls and floors. The test proved that the materials successfully secured the two-hour fire resistive performance, which is the precondition for tall wood mass timber, for the first time in South Korea. As the wood framed structural components developed in this fire certificate test stably secured the fire resistive performance, it is expected to encourage the acquisition of the two-hour fire rated certificates for WFC and promote tall wood mass timber.
