Why the roof of the waterproof membrane and insulation rock wool board to do between the isolation layer?
3, in the insulation layer on whether to protect the isolation layer according to the construction of the insulation layer on the destruction of the role of the waterproof layer. Since the waterproofing membrane has been completed construction, indicating that the flatness has reached a higher demand, and the insulation layer of the grass-roots flatness requirements do not exceed the requirements of the web paving, so waterproof surface without leveling layer, but may need to do protection Isolation layer.
2, the insulation layer can be done on the waterproof above, according to the nature of insulation materials, insulation layer and waterproof layer can be set between the isolation layer or not set. If the waterproof layer on the laying of polystyrene foam board, do not need to do isolation layer; if the block of inorganic insulation materials, such as foam glass, waterproof layer should be set on the cement mortar protective layer; if the waterproof membrane to do Foam concrete or polyurethane block insulation, you can dry in the coil a linoleum for the protection of the isolation layer.
Roof on the waterproof membrane and the insulation between the rock wool board to do isolation reasons:
1, leveling layer is generally in order to make waterproof sheet paving when the formation is not empty drums, and sometimes leveling layer can also increase the bond strength of the substrate and the grassroots. But not all of the membrane paving must be done leveling layer, such as polyethylene polypropylene waterproofing membrane is a special mortar as a binder, not very uneven in the base can be directly on the construction.
The insulation layer of the grassroots level is generally not leveling layer, but do nothing bad, to reduce the block insulation material porosity, improve the insulation effect and the overall strength of the insulation layer is useful.
