Wood is nature's most versatile building material. It is renewable, sustainable, energy efficient to harvest and convert to usable components, easily workable, warm in use, and aesthetically pleasing. Wood has minimal environmental pollution and a range of excellent physical and mechanical properties. For centuries, wood has been used in construction both structurally and as a decorative material.
Due to its natural combustibility, timber burns if exposed to severe fire conditions. However, wood products can be used safely either by improving their fire performance or by choosing the end use conditions properly. Methods for improving the fire performance of wood products include chemical, biochemical and physical modification, as well as structural means. A wide range of wood based products can meet even very stringent requirements, thus extending the market use of wood as a building material.
