PROBLEM TO BE SOLVED: To serve for preventing environmental pollution by improving thermal insulation performance, flame resistant performance or sound absorbing performance of a building by forming a thermal insulation material under the floor or in the ceiling 3 of a building 1 by a special means by using a foaming plastic material, particularly, an industrial waste material. SOLUTION: The thermal insulation material 6 having the height of 200 to 300 mm is formed in clearance 4 under the floor or in the ceiling 3 by blowing a crushed material crushed in the size of 10 to 30 mm of foaming polystyrene or a mixture of this crushed material and a crushed material 5 crushed in the size of 10 to 30 mm of a flame resistant polyurethane waste material under the floor or in the ceiling 3 of the building 1 by a blowing machine; and is constituted by improving the thermal insulation performance, the flame resistant performance and the sound absorbing performance of the building 1.
