Abstract
A collaborative Australian national project funded jointly by the Commonwealth Scientific and Industrial Research Organisation and the Forest & Wood Products Research and Development Corporation has been undertaken to develop a ‘proof of concept’ for a combined fire retardant/wood preservative treatment technology for P. radiata to satisfy the requirements of both the Australian Bushfire and Wood Preservation Standards. The focus of the work was on products that found use in exposed outdoor, above-ground applications. This paper reviews the literature currently available regarding the impregnation of wood with chemical systems that offer resistance to both fire and biodegradation and are also suitable for exterior applications. We have found that in general, researchers have chosen to utilise the dual functionality of boron compounds to achieve both fire retardancy and wood preservation. Often, such systems are applied in multi-step processes, which involve an impregnation step followed by a curing step. Because of the leaching problems associated with boron, a great deal of effort has gone into the development of systems which fix the boron into wood so that its preservation properties can be maintained throughout the useful life of the material.
