MULTIFIX is a dual-density, stone wool insulation board with a glass fiber coating for flat roofing applications

ROCKWOOL MULTIFIX™ is the first stone wool insulation product with a mineral-coated fiberglass facer that is compatible with multiple attachment methods including torched, hot-mopped, self-adhered, cold-adhered and liquid systems.

It can be used as an insulating coverboard over other insulations. In these cases, it improves performance by regulating the temperature of the thermal insulation. In fact, just one layer improves the performance of the entire assembly.

ROCKWOOL MULTIFIX™ has exclusive stone wool dualdensity properties that feature a higher-density top layer, providing strong point load resistance and effective load distribution to minimize puncture damage to the membrane – particularly during installation.
