Tilt & turn vs casement windows
These two are close relatives — both swing on a side hinge — but they behave differently once installed, and the difference usually decides itself on where the window sits and which way it needs to open.
| Tilt & turn | Casement | |
|---|---|---|
| How it opens | Two positions from one handle: tilt in at the top for background ventilation, or turn fully inward like a door. | One position: cranks or pushes outward from a side hinge. |
| Ventilation control | The tilt position gives secure trickle ventilation — the opening is small and at the top. | Open or closed. Partial opening is possible but not secure. |
| Security while ventilating | The tilt position can be left open when the room is unattended. | An open casement is an open window. |
| Sealing and air tightness | Multi-point locking pulls the sash onto the seal at several points around the frame. | Also compresses onto a seal, usually at fewer points. |
| Cleaning | Turn the sash fully in and clean the outside face from inside the room. Useful above ground floor. | The outside face is reached from outside, or by reaching through the opening. |
| Insect screens | Screen sits on the outside, so it does not obstruct the inward-swinging sash. | Screen sits on the inside, between you and the glass. |
| Interior space | The sash swings into the room — keep the reveal clear of blinds, furniture and window seats. | Nothing intrudes into the room. |
| Exterior space | Nothing projects outside. Suits walkways, balconies and tight setbacks. | The sash projects outward — a consideration next to a path or a patio. |
| Egress | The full turn position gives a large clear opening. | Also gives a clear opening; check the clear dimension against the local egress requirement either way. |
| Large sizes | Heavy-duty hardware carries large, heavy sashes; the multi-point gear is designed for it. | Size is limited by what the hinge and operator will carry. |
| Familiarity | European convention. Some U.S. homeowners need the two-position handle explained once. | The U.S. default — no explanation needed. |
| Best fit | Bedrooms, upper floors, tight exterior clearances, passive-house-style air tightness, large openings. | Traditional elevations, rooms with blinds or window seats, kitchens over a sink, and where the crank is what people expect. |
How to decide
Ask what is on both sides of the window. If something projects into the room — a blind, a shutter, a seat, a worktop — the casement is the easier neighbour. If something is outside — a walkway, a balcony, a narrow setback — the tilt & turn is.
Above the ground floor, being able to turn the sash in and clean the outside from inside is worth more than it sounds, and it is the reason many multi-storey projects standardise on tilt & turn.
On performance the tilt & turn usually seals better because the multi-point gear pulls the sash tight at several points. Both are fine windows; this is a question about the room, not about quality.
Can a tilt & turn take an insect screen?
Yes. The screen mounts on the outside, so the sash still swings inward freely. Fixed, removable and retractable screens are all available.
Does a tilt & turn meet egress requirements?
In the full turn position it gives a large clear opening, but egress is a dimensional requirement — check the clear width and height for the specific unit against your local code, the same as you would for a casement.
Which is better for a bedroom?
Usually tilt & turn, because the tilt position ventilates overnight without leaving the window openable from outside.
