一、外围护结构 法国围护结构的保温,在1960～1975年期间,曾采用过轻质混凝土、加气混凝土等材料。随着保温要求的不断提高,到1980年上述单一材料外墙已基本被淘汰。目前大量采用的是以阻燃型发泡聚苯乙烯、岩棉或玻璃棉等高效保温材料,同其他墙材复合而成的外墙。这类高效保温材料在法国的用量达0.4m~3/人·年。即全国每年约使用2000多万m~3。墙体的复合正在从内保温向外保温过渡。他们普遍认识到,外保温较内保温具有减少热桥、提高外墙内表面温度,从而提
First, the external protection structure Insulation of the French envelope structure, during the period from 1960 to 1975, had used lightweight concrete, aerated concrete and other materials. With the continuous improvement of insulation requirements, by 1980 the above-mentioned single material exterior wall has basically been eliminated. At present, a large number of highly-insulated materials, such as flame-retardant foamed polystyrene, rock wool or glass wool, and other wall materials are used as external walls. The use of such high-efficiency insulation materials in France amounts to 0.4m~3/person-year. That is, about 20 million m~3 are used each year in the country. The compounding of the wall is transitioning from the inner insulation to the outer insulation. They generally realized that the external insulation has a thermal bridge to reduce the thermal surface of the external wall and increase the internal surface temperature of the external wall.
