Construction Requirement:

1.The consistency standards of the rock wool slab used 150kg per m3 above, and the intensity of pressure resistance of the slab of 150kg per m3 is equals to or more than 40KN per m2; and the intensity of pressure resistance of the slab of 180kg per m3 is equals to or more than 60KN per m2.

2.To achieve the best effect of heat preservation, double-layer rock wool slab need to lay in the break joint.

3.In the process of fixing the materials of heat preservation and waterproofing, or dealing with the gutter inlet, the special.

4.Fittings needed lo prevent water from contacting the rock wool slab directly.
