DEVELOPMENT OF HEAT INSULATING MATERIALS FOR BUILDINGS IN JAPAN -Research on development of modern building components-

由于各种原因，随着建筑系统的变化，各种构件、材料和建筑系统也在发生变化。然而，普通成分的变化很少被详细记录。在本研究中，我们掌握了隔热材料的历史发展概况。我们的研究包括两个主要的调查，文献研究和听取开发商，建设者和用户。结果按3轴、产品、建筑系统、时间尺度排列成矩阵。摘要：纤维隔热材料：以石棉为例，从开发玻璃棉或岩棉开始，对其作为住宅产品的建筑体系进行了各种考察。如今，它通过采用各种天然材料来关注环境的可持续性。泡沫隔热材料：以合成树脂为起点，经阻燃性检验，应用于住宅建筑。如今，它与纤维隔热材料一样，注重环境的可持续性，趋向于开发无氟氯化碳产品。我们根据建筑材料和产品在特定建筑元素上的演变来把握建筑体系的历史发展，主要是地板建筑体系。同时，对木水泥板等辅助绝热材料以及复合绝热材料进行了研究。最后，明确了历史发展的全貌。各种绝热材料历史发展的重叠特征可以解释为，直到20世纪70年代，绝热材料发展多样化，但近年来由于对性能要求的提高或对环境可持续性的考虑而减少。

Many kinds of components, materials and building systems are changing according to the alteration of building systems due to various reasons. However, the changes of ordinary components are rarely recorded in detail.In this study, we grasped the outline of historical development of heat insulating materials. Our study consist two main investigations, document research and hearing to developer, builder, and user. The results has arranged in matrix by 3 axis, product, building system, and time scale.Abstract of historical development in Heat-Insulating materials as below:Fiber Heat-Insulating materials:Started from development of Glass wool or Rock wool as instance of asbestos, and add various examinations on its building system as product for residential house. Today, it is focused on environmental sustainability by adopt various nature materials.Foamed Heat-Insulating materials:Started from Synthetic-Resin, and adopt to house building by examination on flame-retardant. Today, it is focused on environmental sustainability, same as Fiber Heat-Insulating materials, tends to develop of non-CFC products.We grasped historical development of building system based on evolution of building material and product on particular architectural element, mainly in building system of the floor.And also, our investigation was spread on auxiliary Heat-Insulating Material, as Wood-Cement Board, and also on multiple-material Heat-Insulating Materials. Finally, we make clear the totally aspect of historical development. The overlapped feature on historical development of various Heat-Insulating Materials can be explain that had developed diversity till 1970s, however, it was reduced in lately by rise of demands on performance, or regards for environmental sustainability.
