• Type 3: 8.55mm²
• Type 2: 9.62mm²
• Type 1: 15.90mm²

Extra Long Ties - S/W/425 maximum

Calculation of tie length = cavity width + 125mm

Example:

Cavity width	Tie Length
200mm	325mm
250mm	375mm
300mm	425mm

Giving a standard embedment of 62.5mm. Longer ties available if greater embedment required.

The density of the ties depends on the width of the cavity.

The Irish building regulations require that the density for cavities over 150mm be calculated by a suitably qualified person with knowledge of the specific site.

Extra ties required around all openings at 225mm vertical and placed 150mm from the edge.

Cross-sectional area of the tie is 15.90mm 2
