Fabrication record
What aluminium tilt & turn windows can actually be built to
These are the limits the factory works to, taken from the fabrication data for the system we make this product in. Where a premium route in the same family reaches a better figure, it is shown in the second column and quoted where the project calls for it. Either way this is the envelope, not a quotation: the achievable figures for your opening are confirmed against your drawings and a survey.
| Limit | Standard route | Premium route, where specified |
|---|---|---|
| Frame sightline | 58mm | |
| Panels per run | 1 to 4 | |
| Leaf width | 350 to 1725mm | |
| Height | 400 to 2300mm | up to 2400mm |
| Maximum leaf weight | 130kg | 160kg |
| Glazing unit | 24 to 35mm | 24 to 40mm |
| Glazing options | Double | Double or triple |
| U-value from | 1.2 W/m²KThermal transmittance, triple glazing with Ug 0.7 | 0.71 W/m²K |
| Security | PAS24 |
Configurations available
- Tilt-before-turn, tilt-only, turn-only
- central or off-set (260mm) handle
Tested performance
Two mock-ups were tested at different sizes with different results, so both are shown.
| Tested size | Air permeability | Watertightness | Wind resistance |
|---|---|---|---|
| 1100 x 2300mm | Class 4 (600 Pa) | Class 8A (450 Pa) | Class 2 (1200 Pa) |
| 1500 x 1600mm | Class 4 (600 Pa) | CE1200 (1200 Pa) | CE2400 (2400 Pa) |
Each row is a separate tested mock-up. A class is achieved at a size, so these are not a guarantee for every configuration. The classes that apply to your opening are confirmed at quote.
Any security rating above is the tested performance of the system, held by the system manufacturer. VitrineAlu fabricates to the tested configuration and the test evidence belongs to the system it was tested on. Evidence for the configuration you specify is sent at quote.

How we specify
The right product route is chosen per project
Exact specification (U-value, sizes, weights, security class, finish) is confirmed per project at quote, selected to suit the trade brief.
It means you lead with the outcome: light, security, clean sightlines, usable openings, buildable details and a specification that suits the drawings.
More on how routes are specified: security and PAS 24 routes and energy efficiency and U-values.
Common questions
How does a tilt and turn window actually work?
A tilt and turn window gives two opening modes from one handle. Turn the handle and the sash swings fully inward like a door for cleaning. Turn it back and the top tilts in for secure background air. One frame, two functions, with sashes up to 1.3 m by 2.4 m where specified. See our tilt and turn range, and confirm the sash size for your opening at quote.
Can I leave a tilt and turn window open for ventilation safely?
Yes. The tilt position holds the sash inward at the top for background airflow while it stays mechanically locked on every side. Air permeability meets the highest tested class, with watertightness and wind resistance confirmed per project, so driving rain stays out. Harder to force than a propped sash. Check locking against our security guidance.
Do tilt and turn windows help with cleaning and escape?
Yes. Full turn mode swings the sash into the room, so you clean both glass faces from indoors with no ladder, which suits upper floors and flats. Sashes run up to 1.3 m by 2.4 m at up to 160 kg where specified. Check the clear opening against egress at quote.
What glazing goes in aluminium tilt and turn windows?
Aluminium tilt and turn sashes take double or triple glazing, with acoustic options up to 40 mm reaching Rw 46 dB, plus solar control, obscure and toughened or laminated safety glass. The hinge set carries heavier triple units. Whole-window U-values run from 0.71 W/m²K on the high-insulation route where specified. Confirm the whole-unit Uw for your specification at quote, with the background at energy efficiency.
Where do tilt and turn windows suit best?
Tilt and turn windows suit upper floors, flats, stairwells and openings where an outward sash would foul a walkway, balcony or neighbour. The inward action means no external projection and cleaning from inside, with sashes to 160 kg where specified and a tested security route specified per project. New build or retrofit. Browse the full tilt and turn range, then confirm the sash weight and route at quote.
