Company Mizarstvo Košak d.o.o. is one of the few companies that has the knowledge, technology and references for the production of monumentally protected windows. When making such windows, it is necessary to coordinate with the Institute for Monument Protection and to take into account their requirements. Sometimes the external appearance is enough, but we often have to make a complete copy of the old window. The details of the windows vary according to the complexity of the object. Hardly ever is the same, so we are known for our flexibility.
