A visual barrier windscreen includes a first series of monofilament threads formed in pillar stitches extending in a warp direction and a second series of monofilament threads formed in zigzag stitches extending in a first weft direction relative to the pillar stitches and binding adjacent pillar stitches. A third series of monofilament threads may be formed in zig-zag stitches extending in a second weft direction, opposite to the first weft direction, and also binding adjacent pillar stitches. A pattern of hexagonal wind-passage holes may be formed by cooperation of the pillar stitches and zig-zag stitches. At least a 75-80% visual block may be attained with the cooperation of the pillar stitches and zig-zag stitches.

A fence panel configured to occupy an opening between adjacent pickets of a fence, the fence panel comprising a primary panel, a suspension panel extending substantially horizontally from an upper portion of the primary panel and above a rail of the fence, a vertical portion extending downwardly from the suspension panel behind the rail, a horizontal tab configured to wrap about the rail, at least one flange extending from the primary panel and at least one vertical tab extending from the at least one flange and configured to wrap about a picket.

Disclosed is a fence system. The fence system, comprising: a first post; a second post, wherein each of the first post and the second post comprises a first set of ribs and a second set of ribs; a lower rail, wherein a first end of the lower rail is adapted to terminate at a face of the first set of ribs of the first post and a second end of the lower rail is adapted to terminate at a face of the first set of ribs of the second post; and an upper rail, wherein the lower rail and the upper rail are positioned to receive one or more infill boards, such that the one or more infill boards are adapted to terminate at a face of the second set of ribs of the first post and at a face of the second set of ribs of the second post.

A visual barrier windscreen comprising a first series of monofilament threads, a second series of monofilament threads, and a third series of monofilament threads. The first series of threads may be formed in pillar stitches, the second series of threads may be formed in zig-zag stitches, and the third series of threads may be formed in zig-zag stitches. A pattern of wind-passage holes may be formed by a cooperation of the first series, the second series, and the third series of threads. At least a 75% visual block may be attained with the cooperation of the first series, the second series and the third series of threads. The cooperation of the first series, the second series, and the third series of threads may achieve an air flow permeability that may be greater than 755 cfm/ft.sup.2.

A security barrier which includes a sheet metal shutter formed with a plurality of apertures covered by formations which allow air passage but restrict see-through visibility.
