Wind and Cyclone Ratings

To ensure that your building is designed appropriately to withstand the weather conditions of your exact block of land, the design of every building must be developed specifically for your site and reviewed by an independent engineer.

To make this assessment, the following information must be considered and should be included on any quote you receive:

  • Wind Region
  • Importance Level
  • Terrain Category
  • Topography
  • Shielding
  • Site Wind Speed
  • Do not accept quotes from shed suppliers who refer to 'w' values, i.e. W41 as these codes are obsolete.
  • Quotes from shed suppliers that show wind speeds N2 or C2 or similar, are nominations applicable for houses and some small class 10a sheds. Ask the shed seller for a quote with the site wind speed expressed in metres per second.
