A Fieger In New Pies

Fieger Lamellenfenster GmbH and WindowMaster International A/S have agreed a new global strategic partnership.

Fieger is one of the world’s leading manufacturers of louvre window systems, while WindowMaster is a pioneering natural ventilation specialist.

The agreement will jointly expand both organisations’ operations, increasing both companies’ market share across Europe and North America. The partnership will combine Fieger’s expertise in advanced louvre window design and manufacturing with WindowMaster’s global reach, system integration know-how. Both companies already share a strong focus on energy-efficient building solutions. Together, they aim to provide architects, consultants, façade builders, and building owners with intelligent and scalable ventilation solutions that support healthy buildings.

Operationally, Fieger grants WindowMaster exclusive dealership rights for its louvre solutions in the Nordics, Baltics, United Kingdom and North America. Additionally, WindowMaster can also sell on a non-exclusive agreement in Germany, Switzerland and France, in tandem with Fieger GmbH’s continued promotion and sale of louvre windows in these countries.

Thomas Fieger, CEO, Fieger Lamellenfenster GmbH, says: “By combining our proven expertise in louvre window systems with WindowMaster’s strong international presence and system competence, we are well positioned to accelerate global growth and deliver integrated, high-quality solutions to our customers.”

Erik Boyter, the CEO of WindowMaster International A/S, adds: “Fieger’s louvre solutions are recognised for their quality and performance. By integrating them with our actuators and controls, we can offer our customers an attractive, future-ready solution. The exclusive dealership in key growth markets further strengthens our ability to serve projects globally with a consistent and reliable offering.”
