We developed a hybrid SWP with organic and inorganic heat insulating materials as the core material and verified the performance of fire resistance and mechanics during the development process. By using both inorganic and organic materials together, it exhibits better fire resistance than organic materials alone. In particular, the specifications using fiber-reinforced plaster board plate, which was superior to the specifications using rockwool in terms of mechanics, also showed excellent fire resistance in the ISO 13784-1 test. *1 ㈱フジタ技術センター 主任研究員・博士(学術) (〒 243-0125 神奈川県厚木市小野 2025-1) *2 東京大学大学院工学系研究科建築学専攻 教授・博士(工学)

With exterior tiles, flaking can become a problem as tile ages. To evaluate safety implications caused by the flaking off of tiles, it is necessary to understand the mechanism that causes the flaking. The effects of forces such as temperature or solar radiation are largely unknown. Therefore, we conducted approximately one year of outdoor exposure tests to understand the behavior of the actual tiles due to temperature changes. As a result, we know that behavior of tiles is influenced by strain of tile restraint from concrete wall and this strain is caused by difference in concrete and tile temperatures.
