Integraspec manufactures an “independent panel” system, making it possible to set up inside and outside walls separately. Panels, shipped flat and assembled onsite, can mate with each other in any orientation. It also manufactures 90° and 45° corners that can be rotated to fit either left or right corners. Plastic inserts are molded into the foam to make the units stronger and provide an attachment for drywall screws. Cradles in the ties position horizontal rebar, which can be set in 6-inch increments vertically. President Michel Philippe says that with all the support built into the system, you can place as much as 10 vertical feet of concrete in one pass. It's also possible to integrally form columns in the walls.
