The Slotted Block Tie (Type II) assembly consists of a Slotted Block Plate (Type II), a V-Tie™, and an optional Insulation Support.

Slotted Block Plate (Type II): The Slotted Block Plate (Type II) component as shown in Figure 1, is manufactured from 16 gauge (1.61 mm [0.063"] thick) sheet metal conforming to ASTM Standard A570, and is available in hot dipped galvanized finish (conforming to CSA CAN-A370 and ASTM A153 requirement of 458g/m2/side [1.5 oz/ft2/side] of zinc coating) and stainless steel.

The length of the Slotted Block Plate (Type II) can vary to accommodate block width, insulation plus membrane thickness (I) of 0 mm (0") and up, and air space width (A) of 25 mm (1") and greater.

Two 30 mm (1.2") high by 5.25 mm (0.23") wide slots at the end of the Slotted Block Plate (Type II) allow for up to 60 mm (2.4") of construction adjustability and up to 25 mm (1") differential movement between the plate and the V-Tie™.

Shear keys and corrugated sections provide for adequate fixity within the concrete block wythe. The notch in the plate assures proper positioning within the concrete block backup wythe.

Thermal bridging reducing holes are incorporated within the insulation thickness portion of the Slotted Block Plate (Type II).

V-Tie™: The V-Tie™, as shown in Figure 2, is manufactured from 4.76 mm (0.19") diameter wire conforming to CSA Standard G30.3, and is available in hot dipped galvanized (conforming to CSA CAN3-A370-04 and ASTM A153 requirement of 458 g/m2/side [1.5 oz/ft2/side] of zinc coating) and stainless steel.

The legs of the V-Tie™ are mortared into place at the centerline of the brick veneer. V-Tie™ sizes of 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") lengths are available.

Insulation Support: The Insulation Support is manufactured from polyethylene and is optionally used to secure the sheet insulation in place.
