BirchHaus Windows

European Performance. Built for New England.

BirchHaus Windows brings the performance and durability of European window technology to homes and buildings throughout New England. Designed for cold climates and modern architecture, our windows combine exceptional energy efficiency, clean design, and long-term durability.

Why European Tilt-Turn Windows?

Tilt-turn windows are the standard across much of Europe because they offer superior performance and versatility.

With a single handle, the window can either tilt inward from the top for ventilation or swing open fully for easy cleaning and maximum airflow.

Benefits include:

  • Exceptional air-tightness and insulation
  • Easy cleaning from inside the home
  • Secure ventilation position
  • Modern architectural appearance
  • Long-lasting multi-point hardware

These windows are ideal for energy-efficient homes, Passive House projects, and high-quality renovations.
