    Toprock® DD

    ROCKWOOL Toprock® DD is a high-density, uncoated stone wool insulation board for low-slope roof applications. The product is compatible as the substrate for mechanically-attached (or fastened) roofing systems.

    Non-combustible in nature, Toprock® DD will not develop toxic smoke or promote flame spread even when directly exposed to fire. Also offering improved sound absorbency and dimensional stability, Toprock® DD is designed to maintain performance for the long-term as part of your building envelope.

    Toprock® DD has exclusive stone wool dual-density properties that feature a higher-density top layer that provides strong point load resistance and effective load distribution to minimize puncture damage to the membrane. This is particularly important during installation and maintenance where occasional foot traffic impacts the boards, as well as during severe weather.

    This roofing product can be used either as a base layer of thermal insulation in an assembly with Toprock® DD Plus, as the top layer (coverboard) of a hybrid roof assembly with polyisocyanurate or other roof insulations, or as part of a full-height stone wool solution. ROCKWOOL also offers tapered to zero panels and fabricated accessories such as flute fillers and cant strips.
