Slotted Stud Plate (Type 1) The Slotted Stud Plate (Type I) (Figure 1) 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/ft2/ side), and satisfies the requirements of CSA A370 (which references ASTM A123), ACI 530.1/ASCE 6/TMS 602 (which references ASTM A153, Class B), and the International Codes (which reference ASTM A153, Class B).

The Slotted Stud Plate (Type I) specification length, (S), refers to the actual width of the (steel) stud to which it is connected; the specification length, (IG), refers to the actual thickness of the insulation plus sheathing membrane plus sheathing; and the length, (P), refers to the length of projection of the Slotted Stud Plate (Type I) into the air space.

The overall length of the Slotted Stud Plate (Type I) is 18 mm (0.7”), (P), longer than the specification lengths (S + IG). Specification length can vary to accommodate: standard stud width, (S), of 102 mm (4”), 152 mm (6”) and 203 mm (8”); and thickness of insulation plus sheathing membrane plus sheathing, (IG), of 0 mm (0”) and greater. The Slotted Stud Plate (Type 1)
is available in standard lengths, (IG), 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 55 mm (2.2”) long x 5.8 mm (0.23”) wide slot at the end of the Slotted Stud Plate (Type I) facilitates 50 mm (2”) of construction adjustability and in-service differential movement between the Stud Plate and the V-Tie™.

Holes having 12ø or 19ø are punched through the body of the Slotted Stud Plate. When the plate is mounted, these holes are located within the cavity insulation, and minimize thermal conductivity through the tie system.

Four (4) 6.0 mm (0.24”) diameter screw holes within length, (S), of the Slotted Stud Plate (Type I) provide for plate fastening to the structural backing member. Maximum screw size is #12.

V-Tie™ The V-Tie™ (Figure 3) 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 hot-dip galvanized finish is not less than 460 g/m2 (1.5 oz/ft2) 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 specified thicknesses of masonry veneer and design widths of air space. The V-Tie™ specification length, (L), should be selected to provide for placement of the legs of the V-Tie™ along the centreline of the masonry veneer. Varying lengths of V-Tie™, appropriately selected by the masonry on the jobsite, facilitate in-situ adjustment normal to the structural backing (to accommodate construction tolerances) where the constructed width of air space differs from the design width of air space. Standard lengths of V-Tie™ include 60 mm (2.4”), 80 mm (3.1”), 100 mm (3.9”), 120 mm (4.7”), 140 mm (5.5”), 160 mm (6.3”), 180 mm (7.1”), 200 mm (7.9”), 225 mm (8.9”) and 250 mm (9.8”). For example, the 60 mm (2.4”) V-Tie™ is utilized in the Slotted Stud Tie (Type I) system consisting of 25 mm (1”) air space and 90 mm (3.5”) masonry veneer.

Insulation Support The Insulation Support (Figure 2) is manufactured from polyethylene. It is pressed by hand over the outboard end of the Slotted Stud Plate tightly against the cavity insulation to prevent the insulation from separating from the structural backing/air barrier/sheathing membrane. ­­The friction fit between the Insulation Support and the Slotted Stud Plate restrains the insulation during construction which is commonly installed in advance of the exterior masonry veneer. Subsequent installation of the V-Tie™ sandwiches the Insulation Support between the insulation and V-Tie™, thereby locking the Insulation Support in place and ensuring a reliable and permanent insulation support system.

The insulation support is a standard component of the system, but it is optional where the insulation is otherwise supported, and not required where no insulation is placed within the air space.
