The 90 Degree Corner Block typically makes up 10-15% of the ICF wall assembly on most residential & commercial jobs. This block has six (6) 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 corner block also has one (1) patent pending corner bracket designed like no other in the ICF Industry. This 7/32" thick x 1-1/2" wide corner bracket was engineered to add more strength/support to the block because it connects the inner/outer 1.5 pcf density modified Expanded Polystyrene (EPS) foam panels together and is designed with a round through hole in the outer panel for the installation of a 3/4" PVC or metal pipe to reinforce the corner once the wall is built to eliminate blow-outs during the concrete pour.
