Set the spec and the $/sf is the median of windows that match all of it together (from — windows on signed orders, 97% reconciled). The filters intersect — they don't work in isolation. Type codes (W-1…) are project-local and ignored; size & spec drive the price.
Cost for a window of this spec × its size

Drop in an Eko Okna quote PDF (signed or not). Every window, door and set is scored on its full option sheet — profile, reinforcement, size, glazing, operation, colour, couplings — by a model trained on every signed window since 2021 (retrained nightly, prices at today's level). "History says" = what we'd historically sign for that exact spec; each number carries the nearest signed orders as proof. Within ±10% = in line (model holdout error ~8%). 🚪 Doors are scored against their own signed-door history. ⚠️ Specs we've rarely bought (new glass packages, aluminum systems) read as low-confidence — check the comps.
