Installation of Wiring, Plumbing, Mechanicals and Ventilation
Wiring channels of a sufficient depth per code can be routed out of the panels using a router, rotozip, sawzall or other appropriate tool. Do not cut through panels or completely remove the foam and only remove as much foam and material as is necessary for wiring to maintain the energy efficiency of the panels. Drill studs per code requirements where needed. Use nail plates where needed. Place wire in chase.
Once inspections have been performed and rough wiring has been approved, backfill channels and penetrations with canned polyurethane foam (Great Stuff or equal) and once cured, remove any excess.
Plumbing, Mechanicals & Ventilation
Installation of Plumbing, Mechanicals and Ventilation in Exterior Walls and Removal of Insulation is Not Recommended Unless Utilization of Interior Partitions or Installation of a "Wet Wall" is Not Possible.
Best Practices - For maximum energy efficiency, RAY-CORE highly recommends that every effort be made to avoid the installation of plumbing and ventilation in the exterior RAY-CORE Insulated Panels. In most cases, interior partitions and alternative ventilation solutions can be utilized. Also a “wet wall” framed inside the paneled wally might be considered and utilized. If plumbing or mechanicals must be installed in the panels, take care to remove as little foam as possible, and be certain to backfill all chases and penetrations with canned polyurethane foam (Great Stuff or equal) and once cured, remove any excess.
