1、工程概况
黄陵县医院家属楼老旧小区基础设施配套改造项目9、5、6、8#楼工程，工程地址位黄陵县医院家属楼老旧小区内，本工程高层楼体外墙采用玄武岩防火保温板（TEPS）为主要保温隔热材料，以粘、钉结合方式与墙身固定，抗裂砂浆复合耐碱玻纤网格布为保护增强层，涂料饰面的外墙保温系统。
2、材料性能及要求
2.1 保温材料
2.1.1 玄武岩防火保温板（TEPS）的性能除符合相关标准的规定外，还应符合表1的要求。
2.1.2玄武岩防火保温板（TEPS）的规格为 1200m数控卧式滚齿机m×600mm×4提拉下水5mm，平头式，阻燃型，其尺寸偏差应符合表2的要求。
2.2 粘接砂浆和抹面砂浆
粘接砂浆和抹面砂浆必须符合要求，并由出厂合格证及出厂检验报告。
