Vonderhaus is a leading provider of high-performance fenestration systems to the North American market. Combining centuries-old attention to craftsmanship with a 21st-century focus on technological performance, we partner with leading architects and designers, delivering custom solutions for energy-efficient architecture. We believe the built environment should be designed and built with detailed intentionality. With roots in 18th century Lower Saxony, Germany, Vonderhaus is proud to continue in the tradition of bespoke craftsmanship; a family tradition that has endured generations.

The products at Vonderhaus have achieved an enthusiastic reputation due to their unique design, craftsmanship and our persistent efforts in keeping pace with technological advances in fenestration.

Vonderhaus is equally committed to the environment. Our critical selection of FSC certified materials for our windows and doors ensures that we continue to provide the quality and environmental stewardship synonymous with Vonderhaus. We employ water-based ecologically safe coatings for our wood systems and we are committed to sourcing our aluminum extrusions from manufacturers dedicated to employing sustainable practices such as using renewable energy in their production process.
