Product application:

1. External wall insulation rock wool is application to thin plaster insulation system for exterior wall,mainly used with the typical structure as shown in the following diagram.

2. It is applicable to exterior wall insulation system made of non-grade-A insulating materials. External wall insulation rock wool can effectively prevent flame spread incase of fire and thus provide precious time for escape.

3. External wall insulation rock wool can be also used in the exterior wall insulation system for non-transparent curtain wall.

4. Exterior wall of the existing building can also be modified to from fire barrier of exterior wall,which can improve thermal insulation performance of the building and achieve energy saving effect.
