A two-storey brick building on Gravesend Neck Road, retail on the ground floor and apartments above, being remodeled top to bottom. The upper-floor windows were replaced with new Cortizo aluminum tilt-and-turn units, black, in the existing masonry openings — a window replacement in the plainest sense: the old units out, new frames in, the perimeter sealed and insulated, the interior returns finished by the remodel. Same building, same openings, different windows.
The owner wanted two different things from the same window. On the street, the building sits in a row of brick fronts with double-hung windows, and a run of full-view European sashes would have looked like a different building. So the three front units carry a horizontal bar at the height a double-hung meeting rail would sit, and from the sidewalk they read as the double-hungs their neighbours have — a retro look on a brand-new window. At the back, where nobody is looking from the street, the units are full-view single lites with nothing in the glass.
Both are the same Cortizo tilt-and-turn sash. The bar on the front units is a design element, not a second sash: the whole unit still tilts in at the top for ventilation and swings in fully for cleaning, as the open-sash photograph shows. There is no lower sash to lift, no balance to fail, and no reason to ever put a ladder against the front of the building to clean the glass.
Rental units above a shop, with management that wanted to control how far the windows open. Every sash was fitted with a key-locking handle and a child-lock limiter. Locked, the handle allows the tilt position only — the top of the sash leans in a few inches for air and nothing else moves. With the key, the sash turns and swings open fully. Management holds the keys, tenants get ventilation, and the opening-limiter requirement for a residential window is met by the hardware rather than by a guard screwed into the frame. The same hardware is available on any tilt-and-turn we install; here it was specified across the whole floor.
A double-hung replacement window would have matched the street with less thought. It would also have brought back the things the owner was replacing: two sashes, two balances, weatherstripping that wears at the meeting rail, and a window that has to be cleaned from outside. A Cortizo tilt-and-turn is a single sash compressed against gaskets on all four sides when closed, in a thermally broken frame that will not need attention for decades. On a building being remodeled to hold its value, that is the arithmetic. See our guide to when windows need replacing for the tests, and screens for tilt-and-turn windows for the one question every owner asks next.
