How is wiring installed in the SIPs?
Centered in the EPS core are 1-1/2″ dia. holes running at 14″ and 46″ above the floor and 48″ OC running vertically. These wires are accessible by cutting a hole in the OSB skin for your fixture box at standard locations. Standard wire fishing is then performed. It is important that the person installing the SIPS drills all the 2× plates in the panels so that the electrician can access the wire chases. Refer to SIP detail page for more information.
