Select The Right Door Closer - 10 Tips

Posted at 24/11/2017 12:30:31 Category: Articles

It is important to choose the right door closer but there is a myriad of choices out there so actually pinpointing the right one for your situation can be extremely confusing! In the hope that we can help you to make a reasonably informed choice; we have put together a short guide on the key features that must be taken into consideration.

  1. Consider the door – is it an internal or an external door? Is it inward or outward opening?
    External doors are not fire doors, so you would not need an electromagnetic door closer for these.
    For inward and outward opening doors, some closers can be model specific and angle brackets can sometimes be required.
  1. What space is available? – check the width and height of the frame and door. 
  • Heavier doors will require a closer with a larger power size for optimal performance.
  • If it is an extremely narrow frame, you may need to consider a concealed door closer.
  1. The volume and/or frequency of traffic likely to use the door and the users themselves.   These are split into three groups as per the chart below:

Low usage 

 Up to 10,000 cycles per year.

Medium Usage      

 10,000 – 100,000 cycles per year

 High Usage          

100,000 – 500,000 cycles per year

You also need to consider the needs of the user; for example; the elderly and less abled people may need delayed close to allow them time to pass through the door.

NB.  Hospitals, schools or shopping centres would all be considered to be high volume usage    

  1.      The amount of closer force required - The larger and heavier the door the more force will be required. 

Size

Max door weight

Max door width

1

20 Kg

750mm

2

40 Kg

850mm

3

60 Kg

950mm

4

80 Kg

1100mm

5

100 Kg

1250mm

6

120 Kg

1400mm

 

Often the door closers have adjustable strengths to cater for the size/weight of various types of door.

NB.  In a particularly small room, you may require additional force to overcome air pressure. You may also require a higher power size and a closer with latching action for an external door in order to help reduce slamming.                 

  1.      Mounting Situations
  •        Surface mounted door closers are most commonly used and are available in a variety of types, including:

o   Slide-arm

o   Regular arm surface mounted

o   Parallel arm surface mounted

o   Transom mounted.

 

  •        Overhead and Jamb Concealed door closers are aesthetically pleasing.  They are installed and hidden from view inside the top rail of the door.

 

  •        Floor Springs are the most durable and long lasting option.  They are ideal when aesthetics and functionality are desirable and when dealing with heavy doors or areas with high to extreme traffic.

 

 

 

  1.      Fire Safety

Door closers are an important link in the control of fire and smoke:

  •        Door Closers which are marked CE show that the product is fit for purpose and meets all of the legal fire safety requirements.
  •        They must be fitted correctly and well maintained.
  •        They should not include a mechanical hold-open device. If hold open function is required, then you will need to consider an electromagnetic door closer which is to be connected to the building’s fire alarm system.
  •        All of the above factors can help to save lives in the event of a fire.

 

  1.      Delayed Action
  •        This option allows the door to remain open for a specified period of time. 
  •        The door should then close at an adjustable speed which allows safe passage for wheelchair users or personnel carrying bulky items.

 

  1.      Backcheck
  •        This feature prevents the door being suddenly thrown open either by people or the wind – this can prevent damage to the door, the frame, door hardware and property. 

 

  1.      Closing Speed and Latching Speed
  •        Having an adjustable closing speed determines how quickly the door closes after being opened - This feature allows a longer closing time to enable the disabled, the elderly or the young to pass by safely
  •        Door closers with an adjustable latching speed allow adjustment of the closing speed for the final few degrees of closing.  This is separate to the main closing speed adjustment.  They can be set to either speed up or slow down for these final few inches.

As you can see there are plenty of things to consider when you are choosing which type of door closer is appropriate for your particular and unique situation.  If in any doubt as to what you require, consult an experienced supplier for advice!
