PfostenRiegelSysteme

PfostenRiegelSysteme, translated as mullion-transom systems, are a type of structural facade system used in modern architecture. These systems are characterized by their grid-like construction, where vertical elements (mullions, or Pfosten) are connected by horizontal elements (transoms, or Riegel). This framework typically supports infill panels, which can be made of glass, metal, wood, or other materials, to create a complete facade.

The primary advantage of PfostenRiegelSysteme lies in their flexibility and design versatility. They allow for large expanses of glazing, enabling architects to maximize natural light and create visually open structures. The modular nature of the system also facilitates relatively quick and efficient installation compared to traditional masonry or curtain wall construction. Furthermore, the precise engineering of these systems contributes to good thermal insulation and weatherproofing when properly designed and installed.

These systems are widely employed in commercial buildings, office complexes, shopping centers, and public institutions. Their ability to accommodate diverse panel types and achieve complex geometric forms makes them a popular choice for contemporary building envelopes. The structural integrity is derived from the interconnected network of mullions and transoms, which distribute loads effectively. The term itself originates from German, reflecting its common use and development within German-speaking regions and the broader European construction industry.
