What to do when doors are flung open by wind?

Door is flung open by wind

Many buildings have doors that open to the outside (e.g. emergency exit doors, entrance doors of public buildings, etc). When these doors are knocked open by gusts of wind, heavy damage can occur.

Possible consequences of a door opening without control:

• The door is knocked open by a gust of wind or by storm and crashes into the façade or an object being in the range of the door (e.g. a car). The consequences: torn-out hinges, damaged overhead door closers, broken panes in case of glass doors, damaged façades etc.
• The opening door hits a passerby or is torn out of the hand of the person who is opening it. This can cause considerable injuries.

Back checks against doors that slam open

Installing a back check – with or without regulation. As soon as the opening speed of the door leaf exceeds a certain value, the back check goes into action and slows the opening motion of the door with a controlled speed. There is a fitting model for every application.
