The aim of this study was to investigate the usage possibilities of sunflower stalks in the manufacturing of alternative insulation board, which are left as waste (agro-fiber wastes), in the fields and are useless except for firing like a lot of agricultural wastes in Turkey and in the world every year. The sunflower stalks were designed horizontally to produce the board, and its physical properties were compared to the honeycomb-shaped composite board filled with haft paper (Control board). Urea formaldehyde (UF) resin, Melamine Urea Formaldehyde (MUF) resin, and the D2 (PVA based) adhesives were employed for producing the composite boards. The physical properties [Chemical analysis, specific gravity, SEM, TGA, sound and heat insulations, ultrasonic pulse, LOT (limiting oxygen index), and combustion characteristics] of all the insulation boards were studied.
