Why Tilt And Turn Windows? – 21/11/2016

The vast majority of windows used in Germany are tilt and turn, which is not the norm in the UK. This style accounts for a majority of windows made and sold in Germany now and with good reason. In the UK German Composite tilt and turn windows are catching on.

tilt and turn

The design of the tilt and turn mechanism allows both the most efficient ventilation (directing air upwards in the room) and still allows a means of fire escape with its turn mechanism. You also don’t need to prop the window open when in the tilt position, as the window mechanism allows a fixed tilt inward, and an anti-slam mechanism locks the window from slamming shut if the wind catches the window. Rain is also less likely to get into the building in the tilt position as the water is directed down the window into designed drainage channels.

Like so many things in Germany that work properly, tilt and turn windows are made differently. The driver for this is partly due to Germany energy conservation laws having a higher standard than the UK, but also due to the fact that the German consumer is always looking to the long term. For a product that will last a long time. Not just 5-10 years. By law, a product used in a home must be fit for purpose for a long time. Unlike the UK, where “fit for purpose” usually means that it’s operational when new, and only a short period (usually a year) after. Many manufacturers have bold claims: such as 50 year guarantees. But, when you read the small print, these are so conditional and often mean little practically.

Tilt and Turn: How do they work?

A tilt and turn window fundamentally opens on two axis: tilting when ventilation needed and turning mainly to provide a means of escape from a room in case of fire.

In the tilt position, the window tilts inwards into the room – remaining fixed at the base. This allows ventilation but keeping a good level of security and also shielding off rain. Our heavy duty window opening mechanisms provide security even when open.

Key Benefits

  • Outside glass is easy to clean from inside the building.
  • 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
  • Security is excellent even when open in the tilt position and almost impenetrable with the multi-point locking systems provided by the Wink Haus locking mechanisms.
  • Tilt and turn also allow significant engineering space to fit multiple seals necessary to achieve the airtightness required. Beware of slim frames. They are unlikely to provide superior air and water tightness (but might be attractive in design).
  • Frames can be installed to be covered by plaster reveals thus maximising light
  • Design features such as Georgian bars, flying mullions and robust mechanisms ensure large expanses of glass are all possible. If it can be done in an open out conventional casement, it can be done in tilt and turn too.
  • Tilt and turn also provide 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 UK.

It is worth taking a look German windows. With some offering life expectancy of 85 years, this is a very sensible, modern alternative to outward opening casements.
