Perforated aluminium screening is an attractive method of covering or protecting various aspects of buildings, or alternatively it may be used to decorate, filter, divide or obscure vision. Screens can be fabricated to fit a variety of needs, such creating ‘boxes’ to fit around rooftop plant. Lift winding gear, vents, air conditioning equipment etc. can also be effectively hidden from view. Covering a range of different components in perforated screening can create cool, colourful uniformity in place of a disordered mishmash of machinery. In addition, because it is effectively an open mesh, perforated screening is especially useful where air circulation is a priority.
