Fire Performance of Endospermum malaccense Cross Laminated Timber (CLT) Treated with Fire Retardant

Abstract

This study assessed the fire performance of cross-laminated timber (CLT) made from sesenduk (Endospermum malaccense) painted with a fire retardant. Teknoksafe 2407 (Tk-Exterior) and Teknoksafe 2457 (Tk Interior) fire retardants were prepared and applied to the sesenduk CLT. Fire properties such as surface spread of flame test, charring rate test, fire resistance test, and chemical property changes before and after fire testing were evaluated and compared to Control CLT. The results showed that using fire retardant effectively prevented the fire from spreading.
