SOPRAROCK DD (dual density) is a rigid mineral fiber insulation for use in approved multi-ply membrane and flashing assemblies. SOPRAROCK DD is composed of basalt rock and slag, that when combined, results in insulation with an extremely high melting point. SOPRAROCK DD is water repellent yet vapor permeable and has a higher density top surface.

Installation

Prior to installation, ensure all SOPRAROCK DD panels have not been subject to moisture. Place SOPRAROCK DD in an offset or staggered pattern to ensure board joints are not overlapping in multilayer assemblies. Apply to approved substrate via mechanically fastening. Refer to the SOPREMA SBS Roofing Manual for additional application guidelines.
