建筑材料的环保除了体现在控制化学危害方面,还关注建材的绝热性能,通俗来说,就是材料的保温性能。绝热(保温)性能可通过导热系数反映出来。导热系数是指在稳定传热条件下,1m厚的材料,两侧表面的温差为1度(K,°C),在1小时内,通过1平方米面积传递的热量。保温材料一般是指导热系数≤0.2的材料。
建筑保温绝热材料通常可按材质分有机绝热材料无机绝热材料金属绝热材料
建筑保温绝热材料按形态分多孔状绝热材料纤维状绝热材料粉末状绝热材料层状绝热材料
常见的建筑保温绝热材料产品规范有:
ASTM C533-13 Standard Specification for Calcium Silicate Block and Pipe Thermal Insulation
