Neutras-4 low thermal conductivity wall ties

NEUTRAS-4 light duty wall ties have both low thermal conductivity and high structural performance levels. This means they can be excluded from the current U value calculations in EN ISO 6946 and provide a credible solution to new legislation requirements.  Suitable for buildings with a maximum height of 10m and cavity widths up to 175mm.  (Type 4 Wall Tie)

  • BBA Approved cavity wall ties (Agrément Certificate: 17/5462).
  • Application – A light duty wall tie used in box-form domestic dwellings that have inner and outer leaves of a similar thickness. They are suitable for buildings with a maximum height if 10m and for flat sites where the basic wind speed is up to 27m/s and altitude is not greater than 150m above sea level.
  • Design - Constant drip spiral feature to prevent moisture travelling across the cavity, it can be installed either way up.
  • Material - Manufactured from continuous basalt fibre and vinyl ester resin composite.
  • Durability - Service life of not less than 60 years.
  • Thermal performance - In situations where thermal losses through ties need to be taken into account, the products will adequately resist thermal transmittance through a wall cavity.
  • Compliance - Tested as Type B (sound) and as Type 4 (strength) to BS EN 845-1.
  • Specification – Available for specification on the NBS Source platform.
