- Lumber Selection and Cutting: The picked wood is cut utilizing CNC machinery for accuracy and hand-finished by joiners.
- Glazing and Painting: Windows are glazed in a regulated factory environment to ensure a vacuum seal. They are usually spray-painted with micro-porous finishes that allow the wood to breathe while fending off water.
