Estimating and Panel Installation
Finishes, openings and other applications
InSoFast panels are designed for use with standard Romex® (NM sheathed wire), MC Flex, AC Flex, or rigid metal conduit.
InSoFast wiring chases are located 1¼” below the surface of the panel (National Electric Code – NEC Article 330-4d and 300-41a) and are designed to keep the wiring safely within the panel without the use of protective metal plates.
Electrical Raceways spacing varies according to the panels you are using. The CX 44 panels typically used along the sidewalls, the raceways are spaced horizontally every 24” o.c. and vertically every 22” o.c. as marked by a reference line on the face of the panels.
The chases for the end walls and the ceilings that use either the UX 2.0 or the EXi 2.5 panels their chases are spaced 16″ and 24″ on center. This offers the same protection as a wire running through the center of a 2×4 wall.
EX2.5 Closed-cell, injection-molded EPS foam body achieves R-10 insulation.
UX 2.0 Closed-cell, injection-molded EPS foam body achieves R-8.5 insulation
Cut out the foam with a snap-off blade knife or an electric hot knife as demostrated in the video. Continue to cut out to the nearest horizontal or vertical chase. The vertical chases are clearly marked on the front of the panels. The horizontal chases are located at the top of each panel.
Just press the outlet box against the foam of the InSoFast panel to create a mark. Cut out the foam approximately ¾” larger on all sides than the impression. While a tight-fitting electrical box would look nice, it is better to have extra room to seal around the outlet box with expanding foam.
To make things easier and give you extra room to work with the wiring, cut the opening up to the horizontal chase way.
Press the InSoFast panel in place over the existing outlet to indent the back of the panel. Cut about ½” to 1″ larger than the indentation. If there is conduit, repeat the process to accommodate the conduit. If you have problems seeing the indentation for the conduit, you can mist the conduit with spray paint. This will transfer to the back of the InSoFast panel highlighting the area to be removed. Cut out with router, hot knife or utility knife. Glue the panel into place and fill in gap around the electrical box with the expanding foam. Box extenders can be used with existing electrical boxes.
To transition from an InSoFast wall to a frame wall locate the horizontal or vertical raceways in the InSoFast panel. Locate the stud punch out over the open raceway in the InSoFast panel pull wire through. Follow standard code approved installation procedures. Fill any gap around all the electrical cuts or openings with the expanding foam.
Wiring methods shall be installed and supported in accordance with Table E3802.1.
|Where run parallel with the framing member or furring strip, the wiring shall be not less than 11/4 inches from the edge of a furring strip or a framing member such as a joist, rafter or stud or shall be physically protected. (InSoFast panels raceways satisfy the required protection of 1¼”)|
|Bored holes in framing members for wiring shall be located not less than 11/4 inches from the edge of the framing member or shall be protected with a minimum 0.0625-inch steel plate or sleeve, a listed steel plate or other physical protection.( Raceways that are running through InSoFast studs do not require steel plates because they meet the 1 ¼” depth requirement)|
|Where installed in grooves, to be covered by wallboard, siding, paneling, carpeting, or similar finish, wiring methods shall be protected by 0.0625-inch-thick steel plate, sleeve, or equivalent, a listed steel plate or by not less than 11/4-inch free space for the full length of the groove in which the cable or raceway is installed.(InSoFast panels are engineered with a groove that forms a raceway with the required protection or “free space” of 1 ¼” along the full length of the groove)|
|Securely fastened bushings or grommets shall be provided to protect wiring run through openings in metal framing members. (InSoFast panels have no metal or sharp edges)|
|The maximum number of 90-degree bends shall not exceed four between junction boxes.(This does not apply to NM or Romex® wiring)|
|Bushings shall be provided where entering a box, fitting or enclosure unless the box or fitting is designed to afford equivalent protection. (does not apply to NM or Romex® wiring)|
|Ends of raceways shall be reamed to remove rough edges. (Raceways of InSoFast panels have no metal or sharp edges )|
|Maximum allowable on center support spacing for the wiring method in feet. (The raceways of InSoFast panels provide continuous confinement and support for wiring)|
|Maximum support distance in inches from box or other terminations. (NM or Romex® wiring must be secured in place within 8” of boxes without cable clamps. Securing wiring with expanding foam adhesive (Great Stuff®) satisfies this requirement)|
