Ventilation Louvres on doors are a necessary accessory to provide aeration in many settings or venues. However, chemicals and associated chemical fumes can attack or affect standard aluminium or steel louvres in industrial environment such as chemical manufacturing plants, desalination plants and laboratories. 

Allplastics Engineering recently fabricated a range of customised door louvres in chemical resistant grey PVC sheets which were cut, machined, grooved and glued to provide protection from aggressive fumes and sprays in an industrial application where acids and alkalis were in high concentration.
