Vertical louvres can also be used as screens to hide unappealing plant and machinery on rooftops.

This installation on the roof of an ASDA store near Hull, provides an attractive surround to air conditioning plant, which would otherwise be visible from neighbouring properties.

84R panels are used in a colour matching the existing machinery, to provide a camouflage effect. The support is by SL-4 stringers which make visual contact through the system difficult at normal viewing angles.
