About Arcadia Custom
Where Arcadia earns the reputation.
Real thermal steel
Steel sections with a polyamide thermal break. The slim profiles of classic steel windows with the thermal performance modern code requires.
Slim sightlines
Profiles as narrow as 1¼”. Glass area maximized, frame footprint minimized. The look that aluminum can’t replicate at scale.
Built for the opening
Every window is custom-fabricated to project dimensions. No catalog sizes, no compromises around standard openings.
Steel-look aluminum
Not every project needs true steel. Arcadia’s Thermal Aluminum collection gives us another path for projects that want clean modern lines, lower-maintenance aluminum, and strong performance.
