Since the IFO (Institute for Surface Engineering) was established in 1995, our experts have been involved not only in choosing and making design recommendations for new facade surface finishes, but also in maintaining and caring for surface finishes already exposed to weathering. By having our experts assess and determine the condition of an existing facade, you can decide whether professional yet economical cleaning will suffice or whether you need to renovate. Our recommendations therefore often help to save considerably on costs and achieve the best possible result. Since the Gütegemeinschaft Metallfassadensanierung e.V. (GFS, the Quality Association for Metal Facade Renovations, see www.gfs-online.net) was founded, IFO Institut für Oberflächentechnik GmbH has been its independent testing institute. This means that if renovation work is necessary, our clients have access to a network of companies that specialise in renovating large buildings.
