Each MagWall panel is designed with factory pre-cut electrical chases running vertically in the EPS foam at 16 inches on centre. This allows for installations at intervals similar to conventional construction situations.

The Panel installation (framing) crew will review the electrical service locations as drawn on the building drawings and will pre-drill the upper or lower plates corresponding with the particular chase(s) to be used.

The electrical outlet or switch is drawn on the MagWall at the location of or near one of the chases and at the desired height. The box is then cut out using a router, small blade skill saw or jigsaw and the foam is removed with a small foam cutting hot knife or utility knife. This leaves a cavity intersecting with the wire chase and the wiring is then pulled thru the chase and out through the box/switch cavity.

The electrician can then wire the fixture and place it back in the cavity, pinning it with screws or nails. He then fills all voids around the fixture box with PUR expanding foam.

When the PUR has expanded and set the excess is removed flush with a razor knife. The fixture box is now wired, set and secure ready for finishing. Reno boxes with face mounting plates can also be used and fastened with short screws.

In the case of plumbing vents and line chases required in the MagWall the installation crew and plumber endeavour to place these at a panel connection joint or else create an intermediate joint where the plumbing chase is required by cutting the panel in that location. The same detail as posts for point loads should be followed.

The foam at the joint location is cut back the appropriate depth on one or both panels and panels are pushed together with the exterior sheathing touching and connected edge to edge as usual and the interior foam has been relieved to allow room for the required plumbing. PUR Foam, EPS or batt insulation can be pre packed into the chase if desired but generally is not necessary.

Note: electrical can be run from the joist cavity to the outlet location below and above. This reduces the amount of wire required and speeds installation of wiring. It also splits the wiring zones into the floor above and below reducing zone loads on each floor section.
