The dangers of incorrect door closer specification

UNION, part of ASSA ABLOY Security Solutions, is warning specifiers and installers about the dangers of fitting incorrect door closers for non-insulated metal fire doors.

When looking into door closers you may find that most state that they are approved for metal fire doors. However, what people often don’t realise is that this approval only applies to insulated metal fire doors and they are not fit for non-insulated fire doors.

Non-insulated doors cannot protect against the passage of heat, therefore making the door closers dangerous as they are filled with mineral semi-synthetic mix oil that can ignite when hot enough.

Following Certifire’s revision of their certification to state the type of door, UNION is urging installers and property owners to check their closing devices are suitable.

In addition, UNION’s own door closers offer peace of mind as they are supplied with a glycol mix, which you can rest assured will not ignite due to its testing on non-insulated fire doors by two UKAS accredited fire testing facilities.

David Hindle, Door Closer Specialist at UNION, is advising professionals: “First of all, check all relevant Certifire documentation and make sure this has been updated for any recent amendments. Next, check whether the documentation includes details on the type of fire doors that the door closer has been tested on. Finally, where metal fire doors are covered, are there any restrictions on the type of fire door? By following these steps you can discover if you have any issues to resolve with your door closers.”
