Toprock® DD
Brand: RockwoolRockwool Toprock® DD is a high-density, uncoated stone wool insulation board for low-slope roof applications.
Toprock® DD is a suitable substrate board for all low-slope roof decks and is compatible as the substrate for mechanically attached membrane systems.
Toprock® DD is non-combustible and will not develop toxic smoke or promote flame spread, even when directly exposed to fire.
It can be used either as a base layer of thermal insulation in an assembly with Toprock® DD Plus or as the top layer of a hybrid roof assembly with polyisocyanurate or other roof insulations.
Toprock® DD has exclusive stone wool dual-density 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.
