The process of creating metal windows and doors involves cutting strips from large coils of
steel, cor-ten, stainless, or brass, which are inspected for flaws and rejected if any are found.
The strips are then pushed through rolls that progressively shape the metal strip into its final
shape and work-harden the material, increasing its strength.
The two metal halves are combined firmly together with a fiberglass strengthened extrusion,
which is then coated with a high-density polyurethane resin, injected, and set under extreme
pressure. This forms the Thermally Broken element, which significantly reduces conductivity
and creates a slender and efficient line of steel and architectural bronze windows and doors.
