The windscreen is two poles with a sheet of something resistant to wind between them. It creates a vortex behind it which is much less destructive than the prevailing wind. The problem with a windscreen is it has to be set up in high winds as fast as possible.

This windscreen was supported by 2 balsa poles and was very effective. 4 5lb fishing lines anchored the balsa to 4 1/16" steel rods. It measured 3' x 7'. The material was painter's drop cloth so it wouldn't have survived much wind.

After proving a possible reduction in wind was possible, the windscreen was upgraded to something more durable. This image was of a balsa mockup. It was later upgraded to aluminum.

This heavier and more patriotic wind screen required an aluminum frame. The top piece was 3/4" aluminum angle rod and 7' long. The side pieces were 1/2" aluminum angle rod and 3' long. The side pieces had to be anchored down with tent posts.

Aluminum was much stiffer. The windscreen was fixed to it by spring clamps.

The polyester wind screen still required protection from chafing, in the form of rubber pieces.

The aluminum frame was transported as a single piece, strapped onto the trapezoid. The top piece may be reduced to 6' or split into 2 pieces.

Storing the windscreen required micro bungy cords. If you can't find micry bungy cords, they're made from a bunch of 1" rubber bands and a piece of 16 guage steel wire bent into a hook.

It was much warmer behind the windscreen.
