Technical Data Sheet
Simpson Strong-Tie Stainless Steel Type 4 Wire Wall Tie 50-75mm (1 Unit) (WTS4-200)
Type 4 Wire Wall Tie 50-75mm are suited for box-shaped homes up to 10 metres in height with leaves of comparable thickness, including cavity walls. Use on flat urban areas where the fundamental wind speed does not exceed 25 metres per second and the altitude does not exceed 150 metres above sea level.
Recommended Positioning and Density for walls in which both leaves are 90mm or thicker, masonry ties need to be placed at not less than 2.5 per square metre (900mm horizontal x 450mm vertical centres). Stainless Steel Type 4 Wire Wall Tie 50-75mm should be evenly distributed throughout the wall area, with the exception of around openings and should be staggered where possible.
Insulation Board
Where insulation board is installed within the cavity and restrained by ties with insulation retaining discs, it may be necessary to reduce the horizontal spacing of the ties to 600mm. At vertical edges of an opening, unreturned or unbonded edges, and vertical expansion joints - additional ties should be used at a rate of one per 300mm (height) and located not more than 225mm from the edge.
Length of Tie and Embedment
Stainless Steel Type 4 Wire Wall Tie 50-75mm should be of the correct length to ensure they are fully embedded in the masonry. The tie should have a minimum embedment of 50mm in each leaf, but also allow for site tolerances relating to the cavity width and centring of the tie. The recommended tie lengths will therefore achieve an embedment of between 62.5mm and 75mm. For the most suitable tie length, see the “Recommended Masonry to Masonry Tie Length” table.
Sound Resistance
As stated within the Approved Document E 2003 - Resistance to the Passage of Sound - wall ties used in external and separating cavity walls have to have a minimum value of dynamic stiffness to reduce the transmission of airborne noise.
