在我国目前能源工业尚不够发达,能源供应偏紧的形势下,房屋保温节能自然成了节约热能的重要方面之一。尤其在我国三北严寒地区,每年采暖平均时间超过四个月,必须耗费大量的燃料供房屋取暖。而从我国现存房屋建筑结构上看,绝大部分还是采用的普通砖墙和浮石混凝土墙板建筑材料。这些建筑材料的导热系数大、保温隔热性能差、热工性能不稳定, In the current situation where China’s energy industry is still underdeveloped and energy supply is tight, building insulation and energy conservation are naturally one of the important aspects of energy conservation. Especially in the cold regions of China’s three northern regions, the average annual heating time exceeds four months, and a large amount of fuel must be used for heating the houses. From the perspective of the structure of existing buildings in China, the vast majority of ordinary brick walls and pumice concrete wallboard construction materials are still used. These building materials have large thermal conductivity, poor thermal insulation properties, and unstable thermal performance.
