防火隔离带是外墙外保温系统的一部分，一个完整的系统从里到外一般由墙体、基层、锚栓、胶粘剂、防火隔离带、玻纤网格布、饰面层七部分组成，在这个系统中，要求防火隔离带保温层必须厚度相同，做到全面积的粘贴，而锚栓必须压住底层的网格布。
Fire-proof isolation belt is a part of external wall insulation system. A complete system from inside to outside generally consists of seven parts: wall, base, anchor bolt, adhesive, fire-proof isolation belt, glass fiber mesh cloth and decorative layer. In this system, it is required that the thermal insulation layer of fire-proof isolation belt must be of the same thickness, so that it can be fully adhered. Anchor bolts must hold down the mesh cloth at the bottom.
