A wind guard absolutely will improve your burner efficiency. Ideally you want to shield the burner and as much of the kettle as your liquid-line reaches.
I used a cut-down 30 gallon steel drum with the end cut out of it.
It rests on some brackets that I welded onto my burner stand. I also cut a small opening in it for drain valve access.
