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

由于各种原因，各种构件、材料和建筑系统都会随着建筑系统的变化而发生变化。然而，普通组分的变化很少被详细记录下来，在本研究中，我们掌握了隔热材料历史发展的轮廓。我们的研究包括两个主要调查，文献研究和对开发者、建造者和用户的听证。研究结果按三个轴、产品、建筑体系、时间尺度排列成矩阵。保温材料的历史发展摘要如下：纤维隔热材料：从玻璃棉或岩棉作为石棉的发展开始，并增加了对其建筑系统作为住宅产品的各种检查。今天，人们通过采用各种天然材料来关注环境的可持续发展。发泡隔热材料：从合成树脂开始，经阻燃检测适用于房屋建筑。在关注环境可持续性的今天，与纤维隔热材料一样，非氟氯化碳产品也有发展的趋势。根据建筑材料和产品的演变，我们掌握了建筑体系的历史发展，主要是在地板的建筑体系中，并将研究扩展到辅助隔热材料，如木材-水泥板，以及多材料隔热材料。最后，我们弄清了历史发展的总体面貌。各种隔热材料在历史发展上的重叠特征可以解释为直到20世纪70年代才发展出多样性，但最近由于对性能的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.
