The different types of roof insulation materials and products can be classified in various ways, ... more The different types of roof insulation materials and products can be classified in various ways, for instance, by their structure (e.g. fibres, granules, or cellular), by their form (e.g. panels, sprays, blankets), or, most commonly, by their physical nature (e.g. vegetal, mineral, or synthetic insulation materials). Different materials are used in different areas due to different nature resources and different social development level. This paper chooses northeast China regions and Brussels (one typical European city) as two typical cases to analyze the use of roof insulation materials and technologies during postwar period. Timeline of roof insulation materials in Northeast China Timeline of roof insulation materials in Brussels The use of building materials in Northeastern China tends to use local material, which is cheaper in construction and transport charges. As the timelines show, Chinese dwellings tended to choose more nature materials before 1970s, then modern insulation materials have been gradually promoted after Chinese economic reform. Modern roof insulation material technology has been greatly developed since postwar in Europe, and the modern technology was exported to Asian countries including China. The use of different insulation materials in Brussels in postwar construction can be assessed using examples of newly erected houses in Brussels published in the architectural press between 1945 and 1970. Of the approximately 160 examples for which construction materials were described, the main insulation materials mentioned include glass fibre panels and blankets, wood fibre-cement panels, rock wool, expanded polystyrene, cork, lightweight concrete; double glazing Thermopane and Polyverbel; insulating glass Thermolux; prefabricated boards and sandwich plates Glasal, Linex, etc. About 12% of the houses incorporated both primary and secondary insulation.
