About ERNST MÜLLER GmbH
ERNST MÜLLER GmbH is a window manufacturing company in Windsbach (Middle Franconia) with around 75 employees, specialising in the manufacture of windows, entrance doors and sun protection for new builds and existing buildings.

Products are made in plastic and aluminium construction; for entrance doors, numerous designs and an online configurator for individual entrance areas are available. Reference projects include a major renovation in Erlangen, in which 505 windows in around 100 apartments were replaced with modern, energy-efficient window systems. The company has been in existence for over 60 years and supplies customers in the city and districts of Ansbach, Roth, Weißenburg-Gunzenhausen, Schwabach, Fürth and Erlangen.
