Wind Rating

So what is the wind testing about? It is basically all about having a product that when fitted into an opening has a minimum wind loading resistance that has been tested and approved with a maximum size stipulated.


As of July 2013, to comply with the Construction Products Directive, all shutters which are manufactured for installation over doorways must be tested by a notified test body for their wind loading capability, as per BS EN 12424 and BS 12444.  For doors fitted on to an external facade they must reach a minimum of Wind Class 2 or 59mph winds.   During testing both sides of the curtain must be tested.

It is important that you make us aware that you are in a Windy or Exposed area, so we can help advise you on the right product for your application.  We carry an extensive range of Wind Rated Products
