They seal the same way and open in opposite directions, and everything else follows from that. Which fits a house, a rental, a high floor.
They seal the same way — one sash pressed against a gasket on four sides — and they differ in which way the sash goes. Casement swings out: the biggest ventilation opening, the screen inside, and a sash you cannot clean from inside on a large unit. Tilt-and-turn swings in: cleanable from inside, a secure tilt position for air, key handles for rentals, and a screen that has to live outside. For a house with a view and a breeze, casement. For a rental, a high floor, or anyone who cleans their own windows, tilt-and-turn. For the three-way comparison including double-hungs and the Landmarks question, see casement vs double-hung vs tilt-and-turn.
| Feature | Casement | Tilt-and-Turn |
|---|---|---|
| Opens | Outward, side-hinged, crank or push | Inward: tilts at top, or swings fully in |
| Seal | Compression, four sides | Compression, four sides |
| Ventilation | Full opening; scoops a side breeze | Tilt for secure trickle air; turn for full |
| Cleaning from inside | Only on small units | Always |
| Screen | Interior, standard | Exterior; rebate or exterior-frame system |
| Security when ventilating | Open is open | Tilt position is secure; key handles and limiters |
| Rain while open | Sash sheds it outward | Rain can enter a tilted sash in a driving storm |
| Room-side clearance | None needed | Sash swings into the room; curtains and furniture must clear |
| Wind on an open sash | Outward sash catches it | Inward sash is sheltered |
| Hardware complexity / cost | Middle | Highest |
| Origin / systems | American standard; Pella, Marvin, Andersen; also European | European standard; Cortizo, Reynaers, Alutech, Aluplast |
| Where we install it most | Houses, upper floors, new builds | Rentals, new construction, European-style houses |
A casement opens out on side hinges. The advantages are all about the opening: the whole frame is clear, and angled into a breeze the sash scoops air in; rain on an open sash runs off outward; the screen sits inside where it is easy to fit and remove. The disadvantages follow from the same fact: a large sash cannot be reached from inside to clean, a window air conditioner cannot sit in it, and an open sash on a windy day is a sail.
A tilt-and-turn opens in, on hinges at both the side and the bottom. Turn the handle one way and the top tilts inward a few inches — secure, child-safe, rain-resistant in ordinary weather. Turn it further and the sash swings fully into the room, which is how it is cleaned from inside on any floor. The disadvantages: the sash needs clear space inside, curtains have to be hung to clear it, the screen has to be on the exterior, and a driving storm can put rain through a tilted sash. See screens for tilt-and-turn windows for the screen question, which is the one every owner asks second.
The tilt-and-turn’s key-locking handle is the reason it dominates rental work. Locked, the handle allows the tilt position only; with the key, the sash turns. Management holds the keys, tenants get air, and the opening-limiter requirement for a residential window is met by hardware rather than a guard screwed to the frame. 1192 Gravesend Neck Road and The Elston are built that way. A casement can be fitted with a limiter, but it has no equivalent of the secure tilt position.
On a house, the casement’s clear opening and scooped breeze are hard to beat, and the screen inside is simpler; Pella and Marvin casements on Coleridge Street and Amherst Drive are the type. On a house that wants European aluminum with big lites and a slim frame, the systems come with tilt-and-turn as the default and casement as an option; the Ocean Parkway house uses both. Upper floors and anything above a roof: tilt-and-turn, because it can be cleaned.
The same: both press one sash against a gasket on four sides. Both outperform a sliding or double-hung window on air leakage.
Tilt-and-turn; the sash swings into the room on any floor. A casement cleans from inside only if it opens wide enough to reach around, which a large one does not.
Tilt-and-turn, with key-locking handles and limiters: management controls the swing, tenants get the secure tilt for air.
Inside on a casement, which is simple. Outside on a tilt-and-turn, in the frame rebate or an exterior frame system; the flexible spring-steel screen fits offset uPVC frames only.
Tilt-and-turn, for the hardware. The frame material moves the price more than the operating type.
