The Highest Performing Insulated  Sheathing In The Market 

       The Single-Step Solution to Code Compliance With Better Performance and More Value  

panel pictureROK-ON™ Structural Insulated Sheathing is a high-performance wall insulation system that is revolutionizing the way structures are built. It is made by bonding our proprietary fiberglass reinforced ceramic cement sheathing (FRCC) to expanded polystyrene foam in a thin structural panel. It is attached directly to framing as the exterior sheathing and finished directly, without the additional layers needed to protect traditional sheathing like OSB or gypsum.  

The unique combination of physical properties of our fiberglass reinforced ceramic cement sheathing (FRCC) substantially increase performance and removes the risk of rot, mold or fire damage. 

FRCC benefits

 ROK-ON™ can be used in a multitude of new construction and retrofit insulation applications and is simply applied as the exterior sheathing to substantially improve energy efficiency while meeting new energy and fire codes all in a single step. Simply, ROK-ON™ has better performance, is installed quicker, at a lower cost than other code-compliant assemblies for the building envelope.

Most manufacturers' solutions add layers to their existing assembly to meet the codes, increasing the cost of materials, the time for installation, and the cost of labor.  All of these expenses are having to be absorbed into the supply chain with either lower margins or higher costs. ROK-ON™ was designed to reduce these costs with a system that is code compliant, is installed faster, at a price that is among the lowest in the market.

ROK-ON™ can help solve two of the most common requirements for an external building envelope - fire and moisture management.  ROK-ON™ Structural Insulated Sheathing is non-combustible and has both 1-hour and 2-hour rated assemblies (ASTM E119/UL263). It also will not rot, will not support mold or mildew and is water resistant, something most substrates cannot acheive on their own without added protection.  

Because the face of the panel can accept and hold fasteners, it can help eliminate expensive cladding attachment systems.  For a drainage plane, a simple application of our rainscreen battens can be attached to the panel, which can then accept fasteners for the cladding.  This can save considerable costs and time compared to traditional continuous insulated external wall assemblies.

The result is an building system that has incredible value!  Fewer steps means less labor and subs required for installation and faster completion. It provides significant savings for the building owner and contractor with better overall performance, faster completion, faster occupancy, and reduced costs!
