In view of the contemporary world's demand to create new recycling methods that allow the use of waste materials in industrial processes, whether biodegradable or not, it is planned to develop a thermo-insulating cover panel for hot areas with bagasse fibres from sugar cane. These fibers will be used due to their condition of natural raw material, thus contributing to the reduction of the environmental impact produced by an inadequate disposal of the waste (bagasse) of the cane. The opportunity to reuse this vegetable fiber product enables innovation in the area of biodegradable raw materials, contributing to the substitution of polluting products and petroleum derivatives. To this end, work has been done on the production of nine (9) panels of 30 X 30 cm, with different thicknesses and dosages where the main raw material has been the bagasse fibers of sugarcane from Palmira - Valle del Cauca. The binder used to melt the panels is Portland cement type I (white and grey), and sugar cane molasses. To give the appropriate shape and dimensions to the panels, for-laying slats were used in wood, also of different thicknesses, in addition to the manufacturing processes mentioned above, thermal transmittance tests (u) will be carried out to know their compartment in the face of heat and how suitable and functional these panels can reach.
