The roof-top of deteriorated building is necessary to improve that performance of waterproof and heat insulation is lowered. However, the existing method is difficult to supply due to complicated process and high cost. Therefore, practical condition and demand for occupant considered, it is necessary to develop inexpensive and easy method, such as a floating floor method using thermal insulation. This study is experiments on foundational experiment was conducted on the bending strength. A polyurethane board for experiment forms a square and it has various size that 25cm, 33cm, 50cm, and 100cm. Meanwhile, the uniform load of 200kg/m² which general working load is applied to the bending strength.
