Roxul TopRock Plus
Roxul TopRock Plus stone wool insulation boards can be used for a variety of commercial/industrial low slope, new construction and re-roofing applications, either as a base layer and/or as a coverboard over polyisocyanurate insulation.
These rigid boards are available in monodensity (1”) or dual density (2”-6”) for enhanced point load and puncture resistance. The top surface is impregnated with a bitumen layer that is compatible with a variety of cold- or hot- applied roof membrane applications. Non-impregnated boards are also available on request.
Water repellent yet vapor permeable, TopRock Plus is also noncombustible; a melting point of approximately 2150°F (1177°C) gives it excellent fire resistance properties.
Tremco/Roxul Toprock Plus exceeds the requirements of ASTM C726.
Stone wool is a combination of slag and basalt. The bitumen coating enables TopRock DDPlus to be used with torched and hot-applied membranes.
