Communication

Mark any special cuts on blocks that will be repeated as the wall is stacked with a permanent marker.

Cutting Strategies

Agree on a standard system for identifying and communicating the size and spacing of cuts.

One is the “Spaces and Bars Method”. This method helps to keep a consistent distance between webs. See the graphic and explanation below to see how the Spaces and Bars Method works.

  1. Designated by 3 sets of numbers (e.g. 2-4-2)
  2. The first number is the number of vertical bars of foam only before coming to a web.
  3. The second number is the number of webs, ignoring the foam in between.
  4. The third number is the amount of foam after the last web counted.
An example of a 2-4-2 cut. 2 bars of foam, 4 webs, another 2 bars of foam

Cutting Notes

BuildBlock ICFs all have numbered cut lines every 1 inches. Using this built in tape measure makes it incredibly easy to measure and cut without needing additional tools.

  1. Remember any cut pieces with at least one web can be integrated into the wall in another area.
  2. An easy location to use this material is close to window or door openings where strapping will be required anyway.
  3. Mark the distance to the center line of an opening, size of rough opening, and distance from the edge of a corner to ensure correct size, and placement of openings and penetrations.
