Plate: The Plate is manufactured from 16 gauge sheet steel (1.367 mm [0.0538”] minimum base steel thickness) and is available in both hot-dip galvanized finish and stainless steel. The weight of hot-dip galvanized finish is not less than 460 g/m2/side (1.5 oz/ft.2/side), and satisfies the requirements of CSA A370 (which references ASTM A123), ACI 530.1/ASCE 6/TMS 602, Specification for Masonry Structures (which references ASTM A153, Class B) and the International Codes (which reference ASTM A153, Class B). The incorporation of holes through the mid-body of the Plate minimizes thermal conductivity through the tie system, and a single 25 mm Φ hole through its inboard end ensures mechanical engagement with the poured concrete core of the ICF.

On its outboard end, the length of the Plate is 18 mm (0.7”) longer than the specification length (L). The specification length is the total distance between the exterior face of the board insulation and the exterior face of the structural backing into which the Plate is embedded (for ICF construction, without additional insulating materials included, the specification length is the foam board insulation thickness). The Plate is available in specification lengths (L) of 0 (0”), 28 (1.1”), 41 (1.6”), 54 (2.1”), 67 (2.6”), 79 (3.1”), 92 (3.6”) and 105 (4.1”) mm. Intermediate sizes are also available. The overall length of Plate will also include for an embedment of not less that 50 mm into the concrete core of the ICF.

V-Tie™: The V-Tie™ is manufactured from 4.76 mm (0.19”) diameter wire and is available in both hot-dip galvanized finish and stainless steel. The weight of the hot-dip galvanized finish is not less than 460 g/m2 (1.5 oz/ft.2) and satisfies the requirements of CSA A370 (which references ASTM A123), ACI 530.1/ASCE 6/TMS 602 (which references ASTM A153, 458 g/m2) and the International Codes (which reference ASTM A153, Class B, 458 g/m2).

The V-Tie™ is available in a variety of standard lengths to accommodate different thicknesses of masonry veneer and design widths of air space. The design length of V-Tie™ should be selected so its legs are positioned along the centreline of the masonry veneer. Varying lengths of V-Tie™ can be appropriately selected by the mason on the jobsite to facilitate in-situ adjustment normal to the structural backing (where needed to accommodate construction tolerances). Standard lengths include 60 (2.4”), 80 (3.1”), 100 (3.9”), 120 (4.7”), 140 (5.5”), 160 (6.3”), 180 (7.1”), 200 (7.9”), 225 (8.9”) and 250 mm (9.8”). By selecting the appropriate length of wire V-Tie™, cavity widths of 15 mm (0.59”) to 200 mm (8”) can be accommodated. Specify the V-Tie™ size as the distance from the exterior face of the ICF insulation to the centreline of the masonry veneer.

Tie Spacer: The tie Spacer is a rigid plastic blocking. On site, it is hand-pressed into the vertical slot on the outboard end of the Plate. The inboard face of the Spacer bears against the exterior face of the ICF board insulation to ensure that the Plate is correctly positioned, and that the required depth of Plate engages the ICF unit. The reusable Spacer is subsequently removed from the Plate after the concrete has set, and before insertion of the V-Tie™ into the Plate.
