Hi Bernard_94,
To fully answer your question
Every 450mm high (6 Brick courses high)
Depending on cavity void width will determine how far apart your ties to be spaced.
For instance void is 50mm-75mm ties then 900mm apart (4 bricks long)
75mm-110mm every 750mm apart (3.25 bricks long)
And dont forget every 225mm high (3 bricks) at openings and keep between 150mm-225mm away from the opening jamb
Hope this helps BMG
