  1. Fasteners for steel ledgers provided with part
  2. Minimum steel ledger thickness is 16 gauge, 54mm steel ledger
  3. Loads apply to ICF foam thickness of 3¼ or less.
  4. Concrete should have a minimum compressive rate of f'c = 2,500 psi (17.25 MPa)
  5. The bolts of BURMON-ICFSL must be no closer than 4 inches to the top of wall.

The following spacing tables are an alternative to the ICFWL spacing to replace the building code-prescribed anchor bolt spacing for vertical loads only. They provide the recommended spacing of the ICFWL Ledger Connectors based on the Factored Vertical Resistance of the connector, the load on the floor and the span of the joist. The Designer must determine the design load, the ledger design and the joist design. This table is useful if the Designer already has loads and spans, but not necessarily anchor bolt spacing.

  1. Values shown are maximum spacing distances (inches) based on two-span ledger and simple supported joists. It does not consider concentrated loads. The Engineer of Record can modify the spacing accordingly for other conditions.
  2. Joist and ledger are to be designed by others.
  3. Spacing tables address vertical load applications only. If the connection is designed to resist simultaneous lateral loads, spacing may decrease. Contact Burmon Building Products for additional information.
  4. The ICFWL must be installed no closer than 4" below the top of wall to achieve the connector spacing.
  5. The maximum distance between the end of the ledger and the first ICFWL is 12" as per the recommended splicing installation.
  6. Tables above assume Principal Loads only with Importance Factor = 1.00. For other cases adjust spacing accordingly.
