Heat treatment is one of the environment-friendly ways to treat timber that will lead to the improvement of timber natural quality and equip the timber with new properties by modifying the timber. It is an eco-friendly and alternative treatment method that will modify the properties of timber by using high temperature instead of using chemical preservatives. This paper presents the overview of heat treatment effects on physical, chemical and mechanical properties in the case of heat treated timbers research. It is learned that at temperature over 150 °C, the physical, mechanical and chemical properties of the wood gradually get altered permanently. The research would be essential for the purpose of finding a better alternative to treat the timber to replace the chemical treatment, Copper Chromium Arsenic (CCA) which is not environment friendly. Research had shown that heat treatment on softwood as internal purpose especially in furniture application, hence there is a need to expand this treatment as an alternative method on hardwood timbers to be used in construction industry.
