Rockwool TopRock DD Plus
Rigid insulation board with a bitumen layer
Rockwool TopRock DD Plus is a rigid stone wool insulation board; a bitumen upper layer provides added rigidity, durability and strength while making TopRock DD Plus compatible with torch- or mop-applied membranes. It is intended for commercial/ industrial new building and reroofing applications.
Water repellent yet vapor permeable, TopRock DD Plus is also non-combustible; a melting point of approximately 2150°F (1177°C) gives it excellent fire resistance properties.
Composition:
Stone wool is a combination of slag and basalt. The bitumen coating enables TopRock DDPlus to be used with torched and hot-applied membranes.
