Fibre Boards from Indian Timbers

In a brief introduction the importance of fibre boards as building materials is pointed out. The work done at the Forest Research Institute, Dehra Dun is described, which included investigation on insulation as well as hard boards (both by the Asplund defibrator process as well as by a mild cooking process). The raw materials studied included hard woods, soft woods, bamboos, tapioca stems, tree barks, etc.) The results of strength and other tests are represented in tables as well as in graphs from which the influence of various variables on the properties of the resulting boards can be seen. The results of the investigation show that satisfactory boards can be made from indigenous materials.
