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 1.725 m by 2.3 m on the system we fabricate. 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 1.725 m by 2.3 m at up to 130 kg with the heavy-duty kit. 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 from 24 to 35 mm, with acoustic options (Rw 46 dB on the premium route, where specified), plus solar control, obscure and toughened or laminated safety glass. The hinge set carries heavier triple units. From the system's U-value table: Uw 1.4 W/m²K double-glazed (Ug 1.0), 1.2 triple-glazed (Ug 0.7), at the 1537.5 x 1480 mm test size. Confirmed at quote for your opening. The background is 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 130 kg on the heavy-duty kit 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.
