Steel Doors in Chicago.

A lot of what gets ordered in Chicago is a specific reference: the steel-sash factory window from a Fulton Market loft, rebuilt into a greystone or two-flat that never had one.

In short

Chicago's converted lofts in the West Loop and Fulton Market set the black-steel-and-glass look everyone wants copied into a greystone or two-flat, but a steel frame without a true thermal break sweats and frosts on the interior face once a real zone 5A winter sets in. Crateworks specs that break, or swaps to aluminum for the same industrial sightline with no coating upkeep at all.

Built for Chicago’s climate

Exposed brick and big steel-sash factory windows are the whole point of a Fulton Market or West Loop loft conversion, and that industrial sightline has spread into greystone and two-flat remodels across the North Side that never had a factory window in their history. The cold is what a raw steel frame actually struggles with here: without a genuine thermal break, the frame conducts a zone 5A winter straight through, which shows up as condensation or frost on the interior face on the coldest days. Wind-driven moisture off Lake Michigan is also harder on an unfinished weld than a drier inland winter would be. A true thermal break and a proper powder coat handle both. Where the sightline matters more than the metal underneath, we spec aluminum instead: same black frame, no coating maintenance to manage.

Why it suits Chicago

As North America's largest rail interchange, Chicago pulls freight from either coast, Los Angeles and Long Beach to the west or New York and Norfolk to the east, whichever route is faster that season, so a custom mullion match to an original sash doesn't sit on a single slow corridor. Factory-direct sourcing is what puts the thermal break and the lake-weather coating on the same budget a showroom's stock frame would have cost.

Common questions

Not with the right thermal break. A steel frame without one conducts cold straight through and can frost or sweat on the interior face; we spec the break to prevent it, or swap to aluminum entirely.
We spec a true powder coat for exactly that reason. Wind-driven moisture off Lake Michigan is harder on an unfinished weld than a calmer inland winter, and the coating is what keeps rust from starting there.
That is most of what gets ordered in the West Loop and Fulton Market. Send the mullion pattern from the original sash and we build the replacement, or the interior divider, to match it.
It gives us more routing options. As the largest rail interchange in North America, freight can come from either coast depending on which route is running faster, rather than being locked to one path.
