| Research Abstract |
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.
