Performance Contracting Inc. in Portland used ROK-ON™ Structural Insulated Sheathing (SIS) to prefabricate wall panels on an expansion for LAM Research in Portland Oregon.  The general contractor was Skanska Construction.  The final architectural finish was both full brick on the bottom, with metal siding on the top 1/2 of the building.  

ROK-ON™ was installed on steel framing, in sizes up to 10ft. wide and 22ft. high.  The wall assemblies required a one hour fire rating.  Tyvek® Commercial wrap was used as an additional air/water barrier due to the siding manufacturer's warranty requirements.

Performance Contracting prefabricated the wall assemblies in their off-site facility and trucked the finished panels to the job. With their proprietary design, they were able to install 10 panels per day, with the full enclosure being completed in an estimated 14 days, including some on-site construction.  

The pull-out strength of the ROK-ON™ allowed the metal siding to be attached directly to the panel, without having to secure it to the stud frame.  This reduced both the cost and construction time for the sub-contractor installing the siding.
