Exterior-use timber in multi-storey buildings requires durable fire-retardancy and biological resistance due to its exposure to environmental conditions involving direct water contact. Limited research has been demonstrated regarding whether a single treatment can achieve both biological resistance and fire-retardancy in wood. A previous study demonstrated that the use of ammonium dihydrogen phosphate (ADP)/urea, followed by heat treatment, can significantly enhance fire-retardant properties, even after the water-leaching test by following the EN 84 standard (Lin et al. 2023). This study further examines the material’s biological and dimensional stability after the same type of modification.
