ROK-ON™ Structural Insulated Sheathing

Better – Faster – More Value

12th 3 01 

Tougher code mandates for energy, fire and moisture protection are changing the way buildings are constructed, increasing complexity and driving up costs.  Current solutions are typically comprised of dissimilar materials from many manufacturers which create complex multiple-layered assemblies, adding time to construct and significant cost. Installation takes multiple trips around the building and is difficult to prefabricate.  They often require expensive cladding attachment systems. 


 This is coming when there is a shortage of skilled construction labor which is putting pressure on costs and construction schedules.


The Solution - ROK-ON™   


ROK-ON™ is a single-step application of structural exterior sheathing and continuous insulation with the best product performance in the market.  Unlike traditional sheathing (OSB, gypsum etc), it is:

FRCC benefits

  • Non-combustible
  • Will not rot
  • Will not support mold or mildew.panel picture
  • Water resistant
  • Impact resistant
  • Bug-proof

 As such it does not require the many layers of protection needed from fire and moisture which are common with wood and gypsum based sheathing.

  • Installs using common tools and trades.  No special requirements
  • Contains no harmful ingredients.  Recyclable
  • Comes in 4x8 and 4x9 sheets with a common thickness of 2 ¾"
  • Standard panel is R-10.5.  Exceeds IECC code mandates
  • Fully tested and code compliant to 2017 IECC edition
  • 1-hour and 2-hour rated assemblies (ASTM E 119 / UL 263)
  • 20-year product warranty
  • $10 million per occurance product liability insurance in place
ROK-ON™ is attached directly to steel or wood framing using common tools and trades like any other sheathing but with superior performance.

 Why ROK-ON™?

 As a single-step solution, ROK-ON™ eliminates the multiple layers of traditional code compliant wall assemblies.  Most common solutions are comprised of many layers made of dissimilar materials.  This adds complexity and cost to construction. 


 Traditional Code Compliant Building Envelope

Common code compliant wall assemblies. Complicated systems.  Significant labor and time to construct.

  • Multiple trips around the building
  • Complex multiple-layered assemblies
  • Difficult to prefabricate
  • Requires expensive cladding attachment systems 
  • None of the layers alone can meet the fire and energy requirements


Same Stage with ROK-ON™

ROK-ON™ eliminates the complexity.  A single step solution for a code compliant building envelope. 

  • Installed in the same time as the first layer of traditional sheathing
  • Eliminates multiple trips around the building to install
  • Can accept direct applications of stucco or brick and stone veneers 
  • Can accept and hold fasteners for attachment of cladding
  • Perfect for prefabrication
  • Elimiates or reduces costs for scaffolding / heating and hoarding
  • SIGNIFICANTLY reduces labor costs and time to enclosure
  • Increased productivity 
  • Proven constructibilty and economics on significant projects with some of the largest contractors in North America


ROK-ON™ can accept direct applications of finishes like brick or stone veneers and stucco.  It can accept and hold fasteners for cladding attachment.  This adds tremendous architectural flexibility.
