Zola - another European window maker marketing triple glazed units to the US. This is a aluminum clad wood frame, with a laminated wood sash. The laminates include a synthetic layer they call “Purenit™” which acts as a thermal break - the light layer in the photo above.
Company says they are in Colorado, manufactured in Europe - not sure where. They have several different frame lines, including a PVC line.
Not entirely sure, but I think I am looking at a wood (teak?) window with a brass clad sill.

Another EU window maker with triple glazed in an aluminum clad wood frame - insulation filled AL in this case.
European window with wood interior, and foam exterior clad in extruded fiberglass, going to lengths to make a low profile frame.
Best performing windows? Spruce Fir interior. Cork thermal break. Larch Exterior. Aluminum Cladding optional. German origin, passive house certified, sustainable materials.
Impressive. But how about a window that cost half as much, and did 90% of the energy performance. A window that anybody could have in their house.
Aluminum + bamboo composite window frame.
