The T-Block (Short Leg) typically makes up 1-2% of the ICF wall assembly on most residential and commercial jobs. This block has eight strong, full-length, injection molded plastic ties made from Polypropylene (PP) regrind resin that are well marked with the words “Fox Blocks” located on all sides of the block. These ties secure the three 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 adjacent Straight Blocks. T-Blocks are typically used in walls where two walls intersect each other, an exterior wall to an interior wall. The T-Block is engineered/designed to minimize the amount of form bracing and eliminate blow-outs during the placement of the concrete.
