ROXUL® products are mineral wool fibre insulations made from basalt rock and steel slag. This combination results in a non-combustible product with a melting point of approximately 2150°F (1177°C), which gives it excellent fire resistance properties. ROXUL mineral wool is a water repellent yet vapour permeable material.  Please see the technical product data sheet for specific technical information.


TopRock® delivers advantages that are critical in today’s roofing environment. It is intended for commercial and industrial roof insulation applications and is suitable for both new building and re-roofing applications. TopRock is designed to provide the optimal combination of insulation value, fire resistance, dimensional stability and substrate resilience. Its high density and fibre orientation provide a barrier that reduces sound transmission through the roofing system. In addition, TopRock DD Plus and TopRock DD feature dimensional stability, point-load bearing characteristics, and resistance to fire and high temperature that eliminate the requirement of a cover board in the roofing assembly.


Dual-Density Technology

State-of-the-art technology enables Roxul to produce the unique TopRock DD Plus and TopRock DD dual density products . The main feature of these products is a higher density top layer. This higher density top layer is produced simultaneously with a lower density bottom layer and are combined in a high temperature oven to create a monolithic, rigid roof product.


TopRock® DD Plus is rigid dual-density mineral wool board insulation that is impregnated with a bitumen layer and is compatible with torch or mop applied membrane. 

TopRock® DD is a rigid dual-density mineral wool board insulation that is intended for use with mechanically fastened or ballasted traditional and single ply membranes.


TopRock® MD is a rigid mono-density mineral wool board insulation that is intended for use in tapered systems and fabrication.
