Use the V6 windloading option
In order to work out the precise wind load for a specific item, we need the following details from sales:
Post Code
Distance to see will be worked out by V6 - please do not amend to what survey says!
Location - must know if exposed or not - on V6 for exposed use 'Open Country' , for sheltered - use 'Over 0.5km into Town'
Building height
Altitude - will be worked out by V6
(All wind loading information needs to be relevant to where the item will finally be fitted)
The attachment below is an example of how to calculate the wind load and requirement for a patio.
To work out Isle of Man / Jersey / Guernsey wind loading use post code PO38 2NF then
change distance to sea to 0 - 1KM & Open Country - PA will be PA1369
