The inset form of the Pre-Finished SIP is a variation of the other SIP forms that is finished on both front and back faces with an edge frame structure designed to slide into the frame profile slots. Panels are fashioned for flush mount appearance, leaving frame profile faces free for access to tension plug bolts. Panels may have utilities routes and switch, socket, and other fixtures pre-installed with interior cladding usually designed to work with a complimentary snap-in cover strip. Inset panels are designed to be installed during the assembly of the structural framing and are locked in place by the framing. The are usually installed by vertical insertion before upper horizontal frame members are attached.
