APPROVALS & CODE COMPLIANCE Use of CELBLOX® is approved under IRR Report to ensure compliance with both local and national building codes. These approvals are consistently updated and revised so please make certain you are referencing the most current version of the report on your permit submittal. CELBLOX® is also approved as a Wisconsin Building Product (approval 200710) and has Florida Product approval (4985). A copy of this report can be obtained by contacting the CELBLOX® home office at PRODUCT SPECIFICATIONS CELBLOX® ICFs are used as a permanent formwork for structural concrete in below-grade and above-grade walls. CELBLOX® ICFs form a solid monolithic concrete wall of uniform thickness which can be designed for use in a great variety of construction projects. Each CELBLOX® Insulating Concrete Form (ICF) consists of two 16”x48” expanded polystyrene (EPS) panels with variable core width hinged connectors from 4” to 12” and has 5.33 s/f or surface area. Embedded webs every 8” on center provide the furring strips needed for unlimited interior and exterior finishes. Each block weights about 6 pounds, making them easy to stage on the jobsite. The CELBLOX® ICF system is shipped with hinged connectors folded flat to minimize freight costs and save space. On the job, the forms can be quickly popped open and are ready to stack. 90º and 45º blocks are available to speed construction and provide an exterior corner nailing strip. In accordance with the International Building Code 2006, plain and reinforced walls constructed in accordance with Chapter 19 do not require a vapor retardant. CELBLOX® recommends that you check the local code requirements in your area to ensure compliance. CELBLOX® ICFs can be used to construct fire rated wall assemblies with the following ratings based on concrete core thickness: CONCRETE THICKNESS (inches) FIRE RESISTANCE RATING 4” & 6” 2 8”, 10”, & 12” 4
Lift the window buck into place. Ensure the buck is level, adjusting if necessary, prior to fastening it into place. Place kickers to keep the bucks plumb. Once the bucks are in place, continue building until the top of the buck is reached. All bucks must be supported properly before filling walls with concrete. LINTELS REINFORCEMENT Always check local building codes or engineering specifications for correct lintel reinforcement. Horizontal rebar above opening typically will extend beyond the opening 40 times the bar diameter or as specified by local codes or engineering requirements. For example, #4 rebar would extend 20” beyond the opening. 45 diagonal rebar is installed as shown to divert load from lintel to sides of opening. Lintel reinforcement will vary depending on opening size. Charts for lintel widths up to 16’3” are included in the back of the installation manual. These charts are also available in PCA 100-2007, Prescriptive Design of Exterior Concrete Walls for One- and Two-Family Dwellings, a publication available online from the Portland Cement Association () or the National Association of Home Builders ().
Apply a chalk line 1” above this lowest elevation line Make vertical cuts on either side of the or truss unit location Cut either from the top of the course down, or Cut directly through the form to suit the height of the panel being installed Do not extend the cut below the chalk line in order to provide intermediate support of the hanger brackets Insert each of the 2 insert plates so that large hold perforations sit INSIDE the form cavity by Either sliding them downward from the top of the form or Inserting them horizontally through the form cuts NOTE: Exact placement of insert plates is not crucial if all cuts are made at 90º to EPS face to ensure the bracket faces will always be in plane and in line with the face of the joist or truss frame the concrete has been placed and cured enough for hanging a floor or truss member, chalk a second line at either the top or bottom elevation of the joist to be installed with a laser or transit level Fit the framing member stamped bearing bracket at the bottom end of the joist or truss Slide the joist or truss member and stamped bearing bracket down between form insert plates ready for anchorage at the desired height Once positioned so that the joist is in line with the final chalk line, fasten through both the plate and bracket perforations in an offset triangle fashion to ensure solid anchorage of the stamped bearing bracket into position WALL TO ROOF CONNECTION This shows a steel frame roofing attachment to an ICF wall. This same method would be used for a wood framed roof also. CELBLOX® PRE-POUR CHECKLIST SQUARE, PLUMB, AND LEVEL Are walls and corners, square and level? Are walls plumb everywhere? Is the top of the wall level? Are window and door bucks level, plumb, and square? Are all diagonally braced to maintain square during the pour? Is each buck securely connected to the block? PLANNING Does the layout the plans everywhere?
electrical Electrical wiring runs in both interior and exterior CELBLOX® walls can be cut with a hot knife, router, or electric chain saw to remove EPS at the specified location. Angle the channel so it has a lip on the bottom to hold the cable in place or spot glue with EPS compatible foam. Check local codes to determine wire depth requirements from the wall surface, including drywall. Horizontal runs are easier to cut at the intersection of the panels as the webs are purposely recessed ¼” from the top and bottom of the panels. Electrical box locations can be cut by removing the EPS with a hot knife or router. Boxes can then be screwed to webs using glue or screws or installed in concrete using glue or concrete anchors. . PLUMBING Plumbing channels are made in CELBLOX® walls the same as electrical runs. Pipes up to 2 ½” can be recessed in the wall. Larger pipe may require furring out. To protect pipe from being accidentally pierced by a nail or screw, install a nail plate over the pipe. CABINETS & FIXTURES To surface mount heavy items, such as cabinets, mount 5/8” or thicker plywood or OSB slightly smaller than outline of the cabinet and attach it in numerous places to the webs before mounting the cabinet. The plywood or OSB should be installed prior to drywall installation. The plywood provides a continuous fastening point for the cabinets and serves as the thermal barrier in lieu of gypsum. If cabinets are very heavy, CELBLOX® recommends that they be attached directly to the concrete. Prior to drywall installation, remove EPS and nail 2”x4” lumber (with the 4” dimension flat against the wall) to the concrete making a solid surface to attach the cabinets to later. The Grappler is available from Wind-Lock. It is a 4”x8” mesh that is pushed into the ICF wall prior to drywall installation and becomes a locking washer with 175 pounds per screw of holding power after drywall is in place. It can secure lightweight fixtures such as thermostats, smoke detectors, and towel bars. Screws can be easily backed out with no major holes to repair.
