The Straight Block typically makes up between 80-85% of the ICF wall assembly on most residential and commercial jobs. This block has six strong, full-length injection, molded plastic ties made from Polypropylene (PP) regrind resin that are well marked with the words “Fox Blocks” located on both sides of the block. These ties secure the two pieces of modified Expanded Polystyrene (EPS) foam together that make up each block type. The blocks are stacked tightly together and inter-locked end to end to the desired wall length. Once a single layer or course of ICF blocks is installed, horizontal reinforcing steel bars are inter-locked securely together in the ties of the blocks, then another course of Straight Blocks are placed firmly on top as the wall is built. To improve construction wall strength during installation, each course of blocks should have their end-joint connections staggered in a running bond method from the course adjacent to it. This installation method is typical for all Fox Blocks ICF form types and sizes.
