The origins of IFN can be traced back to the building and construction locksmith’s shop, Klinger, founded in 1931. The IFN group (Internationales Fensternetzwerk or International Window Network), which is 100% under family ownership, unites the expertise, the power of innovation, and the flexibility of several companies.
Interlinking strong companies from the window, doors, façades and sun protection sectors into one future-proof group, “building façades”, ensures our sustainable growth.
Today, the IFN Group is represented by the Internorm, TOPIC, GIG, HSF, Schlotterer, Kastrup, Skaala, Skanva and Neuffer brands in over 33 countries.
