When you specify KÖNNEN GlasHaus windows and doors, you can expect a superior product in the European tilt & turn construction style, but with the ease of local manufacturing. Located just south of Denver in Sedalia, Colorado, our 30,000 square foot production facility features state-of-the-art machinery and software from Europe. After importing product from Germany for years, we can now provide shorter lead times, better pricing and higher levels of service to our North American clients.

Building upon techniques perfected by craftsmen of the past, KÖNNEN credits innovative technology as the key to its efficient production. Skilled factory technicians ensure that no detail is missed through hand-crafted care and quality control. A primary feature of our construction style is in our assembly – KÖNNEN utilizes dowel joinery, which features six dowels at each frame and sash connection.
