Door closer interrupts fire door seal


Recommended Posts

Hello
I am working with a local authority who wish to install an over the door bracket, on the side of a fire door.
This will obviously impede the expansion strip. Is there any legal problems in doing this and how will it affect the fire/smoke resistance of the door? The bracket will cover 70mm of the length of the strip.
Thanks in advance

If the intumescent strip is in the fire door I would imagine it would do more than impede the expansion strip it would prevent that length operating and reduce the fire resistance of the door. If that door is required for the means of escape and there was a fire or audit, then the local authority could find themselves on the wrong side of the law. One solution could be to fit the intumescent strip in the frame and not the door.
