Balanced Door
Features
- Balanced doors are designed to overcome the effects of external wind and internal stack pressures.
- The location of the pivot points distributes door weight more evenly, placing less stress on frame and hardware. (increasing longevity of the door system)
- Only two-thirds of a balanced door protrudes onto exterior sidewalk space.
- Large or heavy doors design is allowed .
- Floor cutouts are not necessary for closer/checking mechanism.

What is a Balanced Door?
A balanced door is a kind of swing door mostly used as an exterior entrance door in a public or commercial building. It is different from all kinds of hinge doors as its unique hardware and mechanical design allow itself to bear and efficiently operate a tall and heavy door leaf. The pedestrians can open it easily without much pulling or pushing force, and the door leaf can make a full close by itself.
The reason making it a “balanced” door is that the exterior wind pressure is distributed by its unique swing path, the location of the door swing fulcrum point makes the door open with ease by leverage and the pivot spring force overcomes the interior stack pressure to fully close the door.
Where to use a balanced door?
*High Traffic Entrance
*High-rise buildings affected by wind tunnel effect
*Where the entrance door needs to be heavy and tall
*Where the door needs to resist the frequent gale
