ARXX Edge insulating concrete forms (ICFs) are assemble-on-site blocks used to build walls and foundations with a concrete core of 4” to 24” or more. The result is in an energy-efficient building envelope that facilitates maximum design flexibility. The unique snap in connectors allow the blocks to be assembled on-site, taking up less space for staging and provides savings on shipping costs. ARXX Edge ICFs are particularly well-suited for commercial projects, especially with tall or very thick walls, or for projects in remote locations. ARXX manufactures a full line of standard, corner, brick ledge, taper top and 45 degree forms in varying nominal concrete core sizes of 4”, 5”, 6”, 8” and 10” and using ARXX Edge Splice Connectors can be assembled to achieve concrete core sizes up to 24”. Standard ARXX Edge forms are 16” high by 48” long.
