Door Closers and Air Pressures:
Understanding air pressures and door controls can be a challenge on some doorways and we have summarised this to help influence and choose the right door control.
Factors that affect these can include:
- The room is air conditioned
- The room is small
- The room is a corridor to a lift shaft
- It is a fire stop wall
- A compartmentation fire stop
- The door has a drop seal
- The door has double or triple blade seals for smoke or sound prevention
- The door is an external door with a threshold
Ways to overcome these can include:
- Slow the door closer down to allow air to escape
- Open a window or air vent on the window
- Increase the power on the door closer unit
- Use a bigger size door closer
- Fit the door with a fire grill
- Fit the room with a air grill or fire grill damper.
We trust these are useful and if you require any further help do not hesitate to contact ourselves.
