Fire Doors & Accessories FAQs

How thick are your fire doors?

  • Our 30 minute fire doors (FD30) are 44mm thick
  • Our 60 minute fire doors (FD60) are 54mm thick

How much can be removed from each edge of a fire door?

The amount that can be removed from the edges of a fire door differs from one door to the next and depends on several factors, including the exact materials used during construction and guidelines from the fire rating certificate. Accurate trimming information can only be provided by the manufacturer on a case-by-case basis after the door has been completed.

Do your fire doors satisfy disability regulations?

All our fire doors satisfy the DDA regulations.

Are your fire doors made with softwood or hardwood?

FD30 fire doors are made of softwood. FD60 fire doors are made of hardwood.

Are your doors suitable for pocket or sliding door systems?

Our fire doors are not certified for use within pocket or sliding door systems and the glazing and panels we provide is fitted using raised beading.

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
  • 54mm = 75kg

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

Do you also supply and fit ironmongery on the doors you supply?

Although we can supply door hinges, door closers and door holders and some other fire rated door accessories we do not have the facility to fit these.

Can remote sounders be fitted to a fire door that requires monitoring?

The Exit Stopper can have remote sounders linked to it using a cable to connect the two. There is no distance restriction to this.

Is there an alternative to a key lock for securing a fire exit door that is used as an entrance?

An alternative to the key operated knob device is to have a code lock handle device. Therefore the tenants would have to enter the four to ten digit code into the handle each time they required access back into the building. The door could also be fitted with a door closer to ensure that it clicks shut.

Can I buy a replacement glass tube for my panic bolt?

If your panic bolt has been used in an emergency, you will need to purchase a replacement tube. Replacement glass tubes are available for Redlam and Ashworth Panic Bolts. Alternatively, Ceramtubesā„¢ can be used in place of glass in Redlam Panic Bolts. These ceramic tubes will not produce sharp edges when the tube is smashed.

Can I update existing fire doors that have no seals to conform to regulations?

Yes, you can use the surface mounted fire and smoke seal kits which are available for both single and double doors.

The single door kit can be fitted to either the door or the door frame.

The double door kit needs to be fitted to the doors rather than the door frame so the gap between the doors is covered.

Please note: Surface-mounted fire door seals must be used in conjunction with certified fire doors and fire door equipment. They cannot turn a standard door into a fire door.

Can fire door seals be fitted to the door instead of the frame?

Yes, fire door seals can be fitted to either the door or the frame

Double doors or door and a half fire doors will need to have fire door seals fitted to the door to ensure that the gap between each leaf is taken into consideration.

What are closing force ratings for fire door closers?

The closing force rating of fire door closers, also called "power size", relates to the maximum width and weight of fire doors that the door closer can reliably close and hold closed.

Can a fire door be fitted with self closing hinges?

Whilst it is possible to fit self closing hinges to a fire door, Safelincs does not recommend their use as they slam the door quickly.
