About Williaam Cox.

Our Plastics products are found in hospitals (anti-bacterial), clean rooms (anti-static), boats (reinforced plastics) and ambulances, sign making, gazebos, walkways, polycarbonate windows (marques, tents & playhouses) etc., proving that not only are aesthetically pleasing but also include excellent technical and physical qualities with minimised maintenance.

The Coxdome brand is synonymous with rooflights and smoke ventilation and its origins can be traced back 50 years when Williaam Cox was founded. The Coxdome range of rooflights can be found on roofs all over Ireland. Schools, hospitals, libraries and universities and indeed anywhere there is a flat roof contain a Coxdome Rooflight. In recent years some notable projects have been Lidl Distribution Centre, Mullingar, Wheatfield Prison, Cork Institute of Technology, Primark HQ and all have contained either Coxdome Rooflights and/or Coxdome Smoke Ventilation Systems.
