[GSBN] windscreen

[Bob Theis]

John Swearingen's comment about bending rainscreens brings up an  
interesting point I'd like clarified:  If the primary function of  
rainscreens is to break the force of the wind, then the "screen"  
needn't be shingled planks as we generally see, but any manner of  
screen with smallish openings set away from the wall behind, yes?

If that's the case, is there any guidance regarding  how small the  
openings should be?

  Yes, yes, it will depend on wind speed,  the thickness of the  
screen,  and variables I'd never imagine, but I'd be happy with an  
oversimplified  generality to guide evaluating screen material  
possibilities. If, for example, I want to make the screen a grill on  
which I grow vines, how dense would it have to be to work, absent the  
growies?

...and my team wants to know how to do the slam dunk home run John  
Straube mentions.
