What is a Tilt Turn Window?

A tilt and turn window opens on two axes: tilting when ventilation is needed, and turning for purge ventilation or when fire egress is needed.

In the ’tilt’ position, the window tilts inwards into the room, remaining fixed at the base. This allows ventilation, whilst still maintaining a high level of security and shielding off the rain. Our heavy-duty window opening mechanisms provide security even when open.

Some Benefits of a Tilt and Turn Window

  • The outside of the glass is very easy to clean from inside
  • Being able to open the same window different ways is incredibly flexible and practical
  • It is possible to have a tilt before turn mechanism and a key lockable handle which allows the window to open in tilt position but avoids the risk of children accidentally opening and falling out of windows
  • Tilt and turn provides excellent fire escapes as the windows can open fully in the turn position. This is unlike top hung or friction hinge windows – so commonly seen in the US.
  • Security is excellent, even when open in the tilt position, and almost impenetrable when closed thanks to the multi-point locking system.
  • Tilt and turn also allow significant engineering space to fit multiple seals necessary to achieve the best possible airtightness rating. Beware of slim frames. They are unlikely to provide superior air and water tightness (but might be attractive in design).
  • Frames can be installed in a check reveal up to external building finishes – this maximises light
  • Design features such as flying mullions and robust mechanisms ensure large expanses of glass are very feasible. If it can be done in an open out conventional casement, it can be done in tilt and turn too.
