Fire Doors & Accessories FAQs
How do you calculate the weight of a fire door?
In order to calculate the weight of a fire door you will need to know the weight per square meter (kg/m2) of the doors core. This is determined using the thickness of the door as follows:
- 44mm = 55kg/m2
- 54mm = 75kg/m2
The calculation below can be used to determine the approximate weight of the fire door. Please note that the calculation does not take glass weight into account.
Width X height X thickness X kg/m2 of the door's core = Weight of fire door.
For example for a door that was 926x2040mm with a thickness of 44mm the following calculation would give an approximate weight:
0.926 X 2.040 X 0.44 X 55 = 45 KG
