Industrial Strength Insulated Concrete Forms (ICF)

The 45 Degree Angle Block typically makes up 1-5% of the ICF wall assembly on most residential & commercial jobs. This block has five (5) strong full length injection molded plastic ties made from Polypropylene (PP)regrind resin that are well marked with the word "Fox Blocks" located on both sides of the block. The 7/32" thick x 1-1/2" wide corner bracket was engineered to add more strength/support to the block by reinforcing the corner once the wall is built to eliminate blow-outs during the concrete pour. The bracket has a marketed exterior fastening surface that is very large on both sides of the block to secure exterior veneer finishes. The ties secure the two pieces of 1.5 pcf density modified Expanded Polystyrene (EPS) foam together that makes up each block type. The blocks are stacked tightly together at the corner locations and inter-locked end to end to the Straight Blocks 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 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.
