Abstract: Durable insulation materials, having combined properties of low thermal conductivity along with low water absorption/high water repellency are suitable for many applications such as insulation to buildings walls and air conditioning pipes and as insulation materials for durable electrical goods such as refrigerators and the insulation of metallic conducting wire. The current invention is a new and novel insulation material based resins and naturally occurring fibers found in plants such as Calotropis procera, a species of flowering plant in the Apocynaceae or dogbane family. The current invention proving to have similar or comparable thermal conductivity than commercially available building insulating material such as rockwool.
