The heat loss during the heating of buildings constitutes about 40% of the greenhouse gas emission that causes global warming. Thus, in order to decrease the energy for heating buildings, various kinds of insulation systems and materials have been used. In this study, by using corn stalks, a polyurethane insulation material was produced. The unit weight, ultrasonic pulse velocity and thermal conductivity coefficients of the produced material were determined. The thermal conductivity coefficient of this composite material was found to be 0.042. The insulation values obtained were in an acceptable range, i.e. they satisfy the Turkish Standard TS 805 EN 60155. Thus, with the zero-waste objective, this study presents an alternative construction material containing a certain type of waste material, also avoiding the environmental problems it causes.
